Getting pregnant is not an easy task, but understanding the essential physiology of the process is the best place to start. In this chapter I will describe the arduous journey that sperm must make through the female genitals to reach the egg, as well as the simultaneous adventure of the egg during which it matures to become genetically ready for fertilization, erupts from the ovary, and gets grabbed by the fallopian tube, fertilized, and then hustled along into the womb at exactly the right moment to implant. Failure of the sperm or egg to make an important connection anywhere along this complicated itinerary will prevent pregnancy from occurring. The vagina is an elastic canal, about four to five inches long. At the end of this canal, in the deepest recess of the vagina, is a structure called the cervix, which is the entrance to the womb, or uterus.
A vasectomy is a permanent form of birth control for males. He ejaculated near my vagina and we Cum against my cervix wearing thin clothing. The withdrawal method is not a reliable source of birth control. It used to be thought that unless sperm resided for a certain period of time outside the male reproductive tract and in the specific fluids of the female reproductive tract, they would not be capable of fertilization, even though in ayainst other respect they looked normal. These outer walls safeguarding the inner confines of the egg represent an impressive barrier to sperm penetration, and a sperm cannot dig its way Teen torture these membranes without the aid of chemicals released from its warhead, the acrosome.

All of us here at SexInfo believe in the importance of spreading knowledge about the ways a female can become pregnant so that men and women can either prevent an unwanted pregnancy or prepare to start a family. We will explore the ways in which a female can become pregnant and the likelihood of pregnancy associated with certain sexual behaviors.
This article is written from the female perspective. If you are intending to prevent pregnancy, we strongly suggest the use of one barrier method of birth control e. We were only kissing. There is no risk of becoming pregnant from kissing alone. We were doing really deep kissing. I performed oral sex and he ejaculated in my mouth. We slept in the same bed but did not do anything sexual.
There is zero chance of pregnancy when two individuals do not engage in sexual activity of any kind. Simply lying beside a male without sexual interaction will not cause you to become pregnant.
We slept in the same bed and he got an erection , nothing else. He ejaculated but we were both wearing thick clothing. If you and your partner were both wearing thick pants and underwear then no, you cannot get pregnant if your partner ejaculates in his pants. He ejaculated while we were in a hot tub or swimming pool.
This is one of the most pervasive myths about becoming pregnant! If his penis never entered your vagina, the chances of getting pregnant are very low and virtually non-existent.
Additionally, the chlorine will kill the sperm regardless of the temperature of the pool. He ejaculated a long way from the vaginal opening. If your partner happens to ejaculate near your vulva external genitalia , there is a slim chance that you could become pregnant. When exposed to air, sperm dry and die relatively quickly. We had anal sex and he did not ejaculate. The anus is part of the digestive system and since the digestive system and the reproductive system are not connected, sperm that gets into the anus cannot reach an egg cell in the fallopian tubes.
He ejaculated near my vagina and we were wearing thin clothing. As mentioned above, sperm can only swim through fluid. If your underwear is thin enough and there is enough semen or vaginal lubrication present, sperm may be able to find their way into your vagina. If your male partner ejaculated on your underwear, there is a small chance you could become pregnant. He ejaculated near my vaginal opening, but not in it. If ejaculation does not occur directly into the vagina, the chances of pregnancy are much lower than if the ejaculate is released inside the vagina.
Nevertheless, there is still a small possibility that pregnancy can occur. When your partner withdraws, it is important to make sure the condom does not slip off of his penis and is properly removed away from the vulva. We had penile-vaginal sex but I'm using a hormonal birth control method correctly. Using these methods incorrectly increases the chances of pregnancy. For more information about how to use each method correctly or how effective each method is, click the links above. If you have other questions about how to use your birth control or how effective it is, contact your healthcare provider.
We had sex but I was using a non-hormonal birth control method correctly. Barrier methods include condoms, diaphragms , cervical caps , and contraceptive sponges. For reliability of condoms, see the paragraph "We had penile-vaginal sex with a condom. Spermicidal cream or jelly is applied onto the diaphragm before insertion to immobilize and kill sperm before they enter the uterus.
It is a silicone cup that fits over the cervix. Suction allows the cup to seal over the cervix, preventing sperm from getting into the uterus. Cervical caps should be used with spermicidal cream or jelly. Spermicide is absorbed in the sponge and continually released.
It is inserted into the uterus by a healthcare professional. The presence of the copper IUD in the uterus acts as a spermicide. A vasectomy is a permanent form of birth control for males. It is a surgical procedure in which the vas deferens are cut, tied, or blocked so that sperm cannot leave the scrotum. This prevents sperm from becoming a part of a male's semen. Here you can see where the incisions to the vas deferens are made. Female sterilization is meant to be a permanent and irreversible form of contraception.
There are two methods: tubal ligation and insertion of tubal implants. Both procedure work by preventing movement of an egg to the uterus and by preventing movement of sperm through the fallopian tubes. We had anal sex while he was wearing a condom and he ejaculated inside me. As mentioned before, the anus is part of the digestive system and since the digestive system and the reproductive system are not connected, sperm that gets into the anus cannot reach an egg cell in the fallopian tubes.
We had sex but I was on my period. It is very possible to get pregnant after having sex while on your period. Women are most fertile approximately one to two weeks after menstruating. Most women do not ovulate while on their period, but eggs can live up to two days while sperm can live for in a woman's body. It is possible for the sperm to find the egg soon after menstruation.
He penetrated me without a condom, but only for a few seconds. Chances of pregnancy are significantly reduced when semen is not deposited directly into the vaginal canal. However, any time the penis comes in contact with the vagina, there is a possibility of pregnancy. Pre-cum lubricates the male's urethra and neutralizes any acidity left from residual urine. Usually pre-cum does not contain sperm, but it may be present if the male has not urinated since his last ejaculation.
We had anal sex without a condom and he ejaculated inside me. Sperm that gets into the anus cannot reach an egg cell in the fallopian tubes. We had penile-vaginal sex with no condom and he ejaculated inside me. You are at the highest risk of becoming pregnant when your partner ejaculates into your vaginal canal and no form of contraception is used.
In order to maximize your protection from pregnancy, it is wise to use a barrier method in conjunction with a hormonal method of contraception, as mentioned before.
We had penile-vaginal sex and the condom broke and he ejaculated inside me. This puts you at a high risk of pregnancy due to the likelihood that semen entered the vagina when the condom broke. It is important to check the quality of the condom and read the directions on the package before putting it one in order to be properly protected. A new condom must be used correctly every time you have sex to prevent pregnancy.
To maximize efficiency, a new condom should be put on before any genital contact and it should be kept on until you are done having sex. Here are some tips for making sure the condom is not damaged before use and is applied properly: 6. We had penile-vaginal sex using the withdrawal method.
The withdrawal method is not a reliable source of birth control. Although you are at a lower risk of pregnancy when your partner withdraws before ejaculation, there is still the potential of pregnancy from pre-cum.
Additionally, the withdrawal method requires a lot of discipline because many males prefer ejaculating inside their partners vagina. It is also possible for him to not pull out in time, resulting in partial ejaculation inside the vagina. We had unprotected sex for the first time. One of the most common myths about getting pregnant is that you cannot get pregnant after having sex for the very first time. The fact is, anytime contraception is not used during intercourse, there is a risk of becoming pregnant.
We hope that this article was able to clarify some of the myths surrounding pregnancy and alleviate any anxieties you may be experiencing. If you have any questions, please Ask the Sexperts.

Can We Get Pregnant If For Her. A woman becomes pregnant when a sperm cell fertilizes the egg cell.
The union of a sperm with an egg is known as conception. To become pregnant , semen must be ejaculated out of a male's penis and into the woman's vagina , up into the cervical opening the os , through the uterus and up into one of two fallopian tubes. If the woman is ovulating, a fertile egg has been released from one of her ovaries into the fallopian tube.
Most women are fertile for about one to two weeks during their menstrual cycle. It is important to note that if ejaculation did not occur, pregnancy is impossible.

How to Get Pregnant - Ch. 1: Natural Pregnancy - The Infertility Center of St. Louis
Getting pregnant is not an easy task, but understanding the essential physiology of the process is the best place to start. In this chapter I will describe the arduous journey that sperm must make through the female genitals to reach the egg, as well as the simultaneous adventure of the egg during which it matures to become genetically ready for fertilization, erupts from the ovary, and gets grabbed by the fallopian tube, fertilized, and then hustled along into the womb at exactly the right moment to implant.
Failure of the sperm or egg to make an important connection anywhere along this complicated itinerary will prevent pregnancy from occurring. The vagina is an elastic canal, about four to five inches long. At the end of this canal, in the deepest recess of the vagina, is a structure called the cervix, which is the entrance to the womb, or uterus. The uterus is a hard, muscular, pear-shaped structure with a narrow, triangular cavity inside, so small that it would barely hold a teaspoonful of fluid.
Yet this is where the fertilized egg must implant itself and grow during the next nine months into a full-size baby. When the baby is ready to be born, the muscles of the uterus contract during labor to squeeze the baby out into the world.
Far back in the corners of the uterus, on each side, are microscopic canals through which the sperm must squeeze in order to reach the fallopian tube, where it may encounter an unfertilized egg. Once the egg has been fertilized, it will pass through the canal in the opposite direction to reach the uterus. These microscopic canals leading from the uterus into the fallopian tubes are only about one-seventieth of an inch in diameter the size of a pinpoint.
The fallopian tubes are four inches long and hang freely in the abdomen. They widen at the ends into large, flowerlike openings called fimbriae. They lie outside of the uterus and fallopian tubes. When an egg is extruded every month from the surface of one of the ovaries ovulation , it is released freely into the abdominal cavity rather than directly into the tube. The fimbria then comes to life like an octopus tentacle and actively grasps the egg, pulling it into the fallopian tube.
The tube swallows the egg, nourishes it before and during fertilization for three days, and then transports it into the uterus. While the male produces billions of sperm every week, the female matures only one of her existing eggs for ovulation each month. Generally, the most fertile eggs are released earlier in life, and of her limited supply of four hundred thousand, about one thousand eggs will die inexorably every month.
Thus with advancing years, though a woman may still be able to get pregnant, she is much less fertile than she was in her youth.
The journey of the egg, or ovum, through the fallopian tube and finally into the uterus after fertilization is extraordinarily hazardous. There are, on the surface of the fimbria, microscopic hairs called cilia, which constantly beat in the direction of the uterus at a fantastically rapid speed and create a kind of conveyor-belt effect for moving the egg into the tube and toward the uterus. The cilia work this magic by digging into the sticky gel, called the cumulus oophorus, that surrounds the egg, and they transport this whole sticky, gooey mass.
The egg itself is invisible to the naked eye, but the gel that envelops it is easily visible. If this sticky substance were not present, and the egg were placed bare upon the surface of the fimbria, the beating of the cilia would never move the egg along.
The cilia are only able to dig in and transport the egg with this sticky, gooey material encasing it. The process of grasping the egg and moving it into the interior of the tube requires only about fifteen to twenty seconds. Once the egg is safely within the tube, it is transported quickly toward the narrower region of the tube, the ampullary-isthmic junction, located two-thirds of the way toward the uterus.
While the egg is held in this location by the tight resistance of the narrow region of the tube, the much tinier sperm nonetheless must struggle through this area of resistance to arrive from the opposite direction.
Once it is fertilized, the egg must be nourished for several days in the ampulla of the tube before it can be allowed to pass into the uterus. If it is transferred into the uterus too soon, it will not be ready to implant, and it will die.
If the transfer of the egg into the uterus is delayed too long, a tubal, or ectopic, pregnancy will occur the fertilized egg will implant in the tube rather than the womb. Once the egg has been allowed to develop in the tube for three or more days, the isthmus suddenly opens up and the early embryo passes quickly into the uterus.
Because the journey of the egg from the ovary to the site of fertilization, its nourishment in the tube, and the precise synchrony of the continuation of its journey into the womb are so intricate, problems with this egg and embryo transport process are frequently responsible for female infertility.
If the egg is not penetrated by sperm soon after ovulation, it becomes overripe and dies. After the egg is released from the ovary, it is only capable of fertilization for about twelve, or possibly at most twenty-four, hours.
The likelihood of intercourse taking place during such a specific interval in any month is rather slight. So nature must provide some mechanism for providing a continuous flow of healthy sperm to the site of fertilization. That way, if intercourse is perhaps one or two days off schedule, some sperm can still arrive at the site of fertilization at the right time.
For this reason, complicated barriers to sperm transport are necessary. The success of IVF demonstrates that if eggs can be recovered at precisely the right time, they can be fertilized in the laboratory with only a small number of sperm. Then the complicated barrier mechanisms provided by nature to allow a slow, continuing flow of a small number of sperm at any moment is not necessary and the large numbers of sperm normally required for fertilization through intercourse are not needed.
Most of the spermatozoa in the ejaculate are contained in the very first portion of fluid that squirts out of the penis and enters the vagina. The remaining squirts usually contain very little sperm. Within just a few minutes after ejaculation, sperm begin to invade a very thick fluid called cervical mucus that is pouring out of the cervix. The sperm must be able to invade the cervix via the cervical mucus by virtue of their own swimming ability. Nothing about the sexual act will help those sperm get into the cervix.
They simply have to swim into the mucus on their own, and this requires a great deal of coordinated, cooperative activity on their part. Ejaculation is a challenging moment for the sperm, as the vagina presents a very harsh, acidic environment, which would normally immobilize them quickly. The alkalinity of the semen the fluid that contains the sperm , as well as the alkalinity of the cervical mucus, allows the sperm to survive in this difficult vaginal milieu.
Any acidity at all quickly kills sperm. Yet even the semen is a potentially dangerous milieu for the sperm; any sperm that remain in the semen for more than two hours are likely to deteriorate. In order to survive long enough to get to the egg and fertilize it, the sperm must gain rapid access to the cervical mucus. Any sperm that have not penetrated the cervical mucus within a half hour after orgasm will not be able to do so later on, because by then they will have lost their ability to swim into the more friendly environment of the cervix.
Spermatozoa can be seen invading the cervical mucus within seconds after ejaculation, but most will not make it. Of some million sperm deposited into the vagina near the cervix in a typical ejaculation, only , ever get into the womb. Thus, over Once the sperm enter the canal of the cervix, they are capable of fertilizing the egg for as long as forty-eight to seventy-two hours, though they may actually live for up to six days. Remember, since the egg is only fertilizable for about twelve hours after ovulation, it is important to have a continuing flow of sperm across the tube so that whenever the egg appears, there will be sperm available.
In this sense, the canal of the cervix can be looked upon as a receptacle through which platoons of spermatozoa migrate and in which some are detained in order to ensure a continuous supply of smaller numbers, over a prolonged period of time, to the deeper recesses of the female where fertilization takes place. Of course, these delaying mechanisms can do more harm than good in infertile couples if events do not allow the invasion of sperm to be mounted successfully.
To understand how this invasion of sperm gets launched effectively, we must first understand the remarkable liquid that covers the opening of the womb-the cervical mucus. The cervical mucus presents a very effective barrier to bacteria and thus protects the womb against infection.
It is a selective filter, which favors normally active sperm and excludes other objects including poor-quality sperm from access. Cervical mucus resembles a thick, clear liquid that can be poured from one container into another. However, in a technical sense, it is not a liquid. As it is being poured, it can actually be cut with scissors; therefore, although it seems to behave as a thick liquid, it also has the characteristics of a very pliable, transparent plastic.
Cervical mucus is absent or very scanty during most of the monthly cycle, gradually becoming more abundant around the middle of the cycle, under the influence of increasing estrogen levels,when ovulation is about to occur.
Just prior to ovulation it becomes almost optically clear, although it is translucent at other times. At the moment when fertilization is possible, near the time of ovulation, the mucus can be stretched out into a very thin strand; at other times in the cycle it is more sticky, and if stretched it will break.
All of these changes in the cervical mucus, which occur around the time prior to ovulation, are designed to help sperm gain access to the uterus. The more liquidlike character, the greater transparency, and the greater stretchability called Spinnbarkheit are all characteristics that favor the successful invasion of an army of sperm.
When the mucus is sticky and thick, not as abundant, and translucent rather than transparent, it is difficult if not impossible for any sperm to gain access.
Microscopically, the cervical mucus consists of a dense mesh that, during most of the monthly cycle, represents a solid barrier to invasion. Just prior to ovulation, under the effect of the female hormone estrogen, mucus production rises tenfold, and the water content of the mucus increases.
The otherwise impenetrable mesh opens up and allows a successful invasion of sperm. When semen first reaches the cervical mucus after ejaculation, a clear barrier line can be seen separating the two different fluids. Soon, however, phalanges of sperm begin to penetrate the mucus, forming branching structures that invade it. Sperm at first seem to bounce against the cervical mucus without any evidence that they will ever be able to gain access. Their movements while in the ejaculate are haphazard and not specifically aimed toward the mucus.
However, within a matter of minutes, one or two spermatozoa begin to make an indentation in the line separating the cervical mucus from the ejaculate. Once one sperm has been able to initiate the penetration of the mucus, other sperm then quickly follow at that same point of entry.
Sperm then continue to invade the cervical mucus at that point much like a single-file line of army ants. Only one or two spermatozoa at a time can pass through this entrance. The sperm swim in a straightforward direction along parallel rows of the invisible microscopic molecular structure of the mucus. Once this invasion of the cervical mucus has been established, sperm can reach the fallopian tubes in about thirty minutes.
Pregnancy would not be likely if all the sperm got into the fallopian tubes at one time, because they would soon pass on into the abdominal cavity, and not be available to fertilize the egg except during a very brief, lucky interval.
If they were not lucky enough to pass through the fallopian tube at exactly the moment of ovulation or within twelve hours of ovulation , they would be long gone by the time the egg arrived. Thus, nature had to invent some mechanism for allowing a continuous entry to the site of fertilization by a smaller number of sperm.
To accomplish this, the cervix and the cervical mucus act as a reservoir from which spermatozoa are slowly released into the uterus and up to the fallopian tubes over a period of several days. During the course of their odyssey toward the site of fertilization, the sperm undergo capacitation, a process that was not fully understood before the advent of IVF. It used to be thought that unless sperm resided for a certain period of time outside the male reproductive tract and in the specific fluids of the female reproductive tract, they would not be capable of fertilization, even though in every other respect they looked normal.
It was thought that this process of capacitation could occur only in the fluids of the female reproductive tract while the sperm migrated toward the egg. However, in vitro fertilization has demonstrated that capacitation of sperm once considered one of the greatest problems in successfully achieving test-tube babies can occur in relatively simple, nonspecific fluids available in any laboratory.
Thus, sperm seem to have a natural tendency toward developing capacitation for fertilization on their own and simply require a period of several hours outside the semen. In nature this happens when they leave the semen and enter the cervical mucus. In the IVF laboratory it happens when sperm are separated from the semen by virtually any washing technique. Before egg and sperm can ever meet up in the fallopian tube, the egg must be matured and extruded from the ovary in a process called ovulation.
Since many women who seem unable to have children owe their problems to a disturbance in ovulation, and since part of the IVF procedure involves stimulating the ovaries to prepare many eggs for fertilization, we should understand how the repeatable, monthly series of changes leading to ovulation occurs naturally in the ovary.
