Completion Of Meiosis And Union Of The Male And Female Genes
Once the first sperm has successfully invaded the zona pellucida of the egg, a remarkable event takes place. The membrane that surrounds the egg within the zona fuses with the membrane of the sperm, and the sperm and the egg become one. The egg literally swallows the sperm as these two microscopic entities initiate the development of a new human being.
Also, at this moment the outer zona pellucida becomes transformed into a rigid barrier so impenetrable that other sperm, despite all the chemicals in their acrosomes, cannot possibly enter. Many sperm can be seen attempting to enter the egg in competition with the one that made it first, but their efforts are in vain. Once the egg has been successfully penetrated by a single sperm it shuts its walls so tightly that none of the followers can get through. This protects the fertilized egg from the entrance of extra chromosomes , which would cause a genetically impossible fetus, and a miscarriage.
Penetration of the egg membrane by the sperm head also sets in motion the second meiotic division of the egg with the release of the second polar body. It is this second meiotic division that reduces the number of the eggs chromosomes to half so that sperm and egg genes can unite.
Legs Up For Pregnancy: Does It Work
A few weeks ago I came across a large randomized study in which 479 women were randomly assigned to either 15 minutes of keeping their legs up after insemination or to immediately move on. The results showed that the cumulative pregnancy rate was comparable between the two groups.
As a matter of fact, the group that immediately continued to move had a slightly higher number of pregnancies . However, a clear tendency of legs up NOT helping with fertilization, or maybe even a slight worsening of the chances, was present.
To conclude, gravity will not work against you and there is no reason for you to fight it.
For similar reasons, positions taken during intercourse dont matter either.
As much as we would want some myths to hold true, there are no sexual positions more conducive to getting pregnant than others.
There are no sexual positions more conducive to getting pregnant than others.
In terms of positions either during or after sex, there is not much you can do to make a pregnancy more likely to happen. However, there are a few things you can avoid doing, as they do harm the chances of conception.
Basically, anything that negatively interferes with egg quality or sperm motility once in your body should be avoided.
Saliva can negatively interfere with sperm motility, so those wishing to get pregnant should better avoid oral sex prior to intercourse .
Can You Get Pregnant While On Your Period
The short answer is yes. It’s not likely, but it’s possible, especially if you have irregular cycles, short cycles, or simply misinterpret some mid-cycle spotting as your period.
“For example, let’s say your period is typically five days and you have sex on day five, and then you happen to ovulate early, like on day nine of your cycle,” said Dr. Mary Jane Minkin, an OB-GYN and clinical professor of obstetrics at Yale University in New Haven, Connecticut. “The chance of having good sperm hanging around for those four or five days is not good, but it’s possible.”

What To Do After Sex When Ttc Peeing Laying Down And Other Tips
When we were young, we were taught that getting pregnant was an easy task. All you had to do was have unprotected sex, and suddenly you would become pregnant!
But when you begin trying to conceive , you realize that conceiving a baby is much harder than you thought when you were young. Unfortunately, getting pregnant isnt always as simple as getting down with your partner there are many moving parts to think about! For example, as you probably already know, you need to time sex with your fertile window in order to get pregnant.
Youve probably done a lot of research about what to do before and during sex to help your pregnancy chances. You may also be wondering what to do after youve finished doing the deed. Maybe you heard an old wives tale that holding your legs up after sex will help you get pregnant, or youre wondering if peeing after sex will kill your partners sperm.
Sadly, we arent taught much about how fertility works in school and your questions may have gone unanswered for months or even years. If youre wondering what to do after sex when TTC, look no further: read on to discover which tips work according to science and which pieces of wisdom may be more fiction than fact.
How Often Should You Have Sex To Get Pregnant
There is no magic number of how many times you have to have sex to get pregnant. When you’re trying to conceive, when you have sex is more important than the number of times you have sex. But that’s not to say that you can’t maximize your chances of getting pregnant by having sex more than once during your fertile window.
You may think that cutting down on sex to “save” spermor only having sex during ovulationwill make getting pregnant easier. But abstaining too much can throw off conception odds.
Indeed, while holding off on sex can increase sperm count, it can also decrease sperm motility. What’s more, “it’s easy to miss the fertile period if sex is limited only to when you think you’re ovulating, because many people believe they’re ovulating when they actually aren’t,” says Samuel Wood, M.D., medical director at The Reproductive Sciences Center in La Jolla, California.
There is the risk creating stress by forcing yourself to sticking to a schedule. The best bet is to have as much sex as you feel comfortable having and using your ovulation calendar to help guide when the optimal times may be.

Being On The Pill For Too Long Will Delay Pregnancy
This is a myth. If youve spent years of your life trying not to get pregnant, its only natural to wonder if it will take a while to get things back on track.
In good news, it wont. For some women, fertility returns as soon as they stop using the pill, but for others, it may take a month or so to resume ovulation as long as there are no other issues going on, of course.
Is It Normal For Uterus To Tip Backwards During Pregnancy
Youll also be reassured to know that having a uterus that tips backwards is not a problem during pregnancy either. It will reposition on its own around the 10 th to 12 th weeks in order to allow your baby to develop healthily.
What causes the uterus to be stuck in a backwards position?
These include: Endometriosis. Endometrial scar tissue or adhesions can cause the uterus to stick in a backwards position, almost like gluing it in place. Fibroids. Uterine fibroids can cause the uterus to become stuck, misshapen, or to tilt backwards. Pelvic inflammatory disease .

What Were The Results Of The Study
The couples received an average of 2.4 cycles of insemination in the lying down group, and 2.5 cycles in the immediate mobilisation group. The researchers found that lying down for 15 minutes after insemination increased the proportion of couples who achieved an ongoing pregnancy compared with immediate mobilisation . This represented an increase of 50% in the chances of an ongoing pregnancy .
Lying down after insemination reduced the time it took to achieve an ongoing pregnancy. The women in the lying down group also had a higher rate of live births, with 27% having a live birth compared with 17% in the immediate mobilisation group.
Ten of the pregnancies did not occur through artificial insemination, nine occurred naturally between treatment cycles and one woman became pregnant after she began receiving IVF during the study. When the researchers excluded these pregnancies from their analysis, it did not affect the results.
Saliva Is The Most Fertility
This is a myth. Youd think that all bodily fluids would just get along but no, not so. Saliva is a sperm killer. In fact, the truth is that most lubricants and massage oils are fertility-unfriendly so best to go without when youre trying to make a baby, or choose a fertility-friendly lubricant like canola oil or one containing hydroxyethylcellulose.

How Long Does It Take To Get Pregnant After Sex
Conception results from sperm fertilizing the egg in the reproductive tract, which could happen up to six days after having sex depending on where in your cycle you were at the time. From there, the fertilized egg will travel to the uterus and implant in the uterine lining to begin the pregnancy. So how long after sex does implantation occur? Usually around six to 12 days. Some people notice implantation symptoms like light spotting or cramping, while others don’t .
But how long do you have to have TTC sex before you finally get pregnant? That answer depends on a variety of fertility factors, but up to 90% of people trying to conceive will get pregnant within a year.

Will Lying On My Back With My Legs In The Air After Intercourse Help Me Get Pregnant
Theres no strong evidence to suggest that lying on your back or tilting your hips for 20 minutes after intercourse improves the chance of getting pregnant. On the other hand, it wont hurt your chances either.
Lying down helps the sperm to pool near the cervix and may help more sperm on their journey. In general, though, healthy sperm will find their way into the fallopian tubes regardless of what you do.
What Does It Mean If Your Uterus Is Upside Down
A retroverted uterus means the uterus is tipped backwards so that it aims towards the rectum instead of forward towards the belly. Some women may experience symptoms including painful sex. In most cases, a retroverted uterus wont cause any problems during pregnancy.
Does a tilted uterus mean C section?
While some women wonder if having a tilted uterus can cause childbirth complications or result in a C-section, its highly unlikely. After the first trimester, your uterus will have grown so large that it wont be tilted one way or another.

Can You Get Pregnant While Breastfeeding
“Fertility is definitely diminished when you’re breastfeeding, but women get pregnant all the time when they’re breastfeeding,” Streicher said.
There are some hormonal changes happening in the body when a woman is breastfeeding, which could affect ovulation and also help explain why some women don’t get their periods while they’re nursing, but using breastfeeding as a form of contraception isn’t a safe bet.
You Cant Get Pregnant When You Have Your Period
This is a myth. As crazy as it sounds, you might actually conceive when you have your period. Because of the way a womans cycle fluctuates, the day ovulation starts can change from month to month, which means you cant count on all the sperm from period sex being dead and gone by the time you ovulate next.

Lying Down ‘boosts Insemination’
Women undergoing fertility treatment with artificial insemination may boost their chances of pregnancy if they lie still afterwards, the BBC has reported.
These findings come from a Dutch study of 391 couples who were treated for conception problems. The researchers asked the women to lie down for 15 minutes or get up immediately after having sperm inserted directly into their uterus . It found that 27% of the women who lay down after insemination went on to have a baby, compared with 17% of women who got up and moved around. This study used a robust design to investigate the effects of lying down after intrauterine insemination. The study had other strengths, including a relatively large number of participants and the fact that all the participants were followed up. This increases the likelihood that the results are reliable.
An accompanying editorial article on the research reported that there were lower pregnancy rates in this study than in other centres that do not use immobilisation. This could be because different centres use different techniques, or because patients fertility problems have different causes. This study promotes the potential benefits of lying down after insemination, and may encourage centres that do not already do so to try this practice.
Can You Get Pregnant Right After Stopping The Pill
“People have this idea that hormones from the pill will stay in their system for a while,” Streicher said. “That’s not true.”
For most women, their bodies adjust pretty quickly after stopping the pill.
Within a month or two, most will start ovulating again and their fertility returns to normal, Edelstein said.
“The issue, of course, is that while the birth control pills don’t cause any fertility issues, they might mask fertility issues, like if a woman has underlying ovulation problem,” he added. “You wouldn’t know it when you’re on the birth control pill.”

How Can I Get Pregnant With An Inverted Uterus
To have the best chance at conception with a retroverted uterus, fertility doctor Dr. Marc Sklar, of the Fertility TV YouTube channel, suggests having sex from behind, or doggy style .
Is it harder to conceive if you have a tilted uterus?
A retroverted uterus does not in and of itself cause difficulty conceiving. That being said, some diseases that distort normal pelvic anatomy, such as endometriosis or fibroids, can pull the uterus backward. In these cases, infertility is caused by the disease affecting the uterus, not by the tilted uterus itself.

“If you never skip months and your periods are always spot-on, I think the chances of you getting pregnant are slim to none,” Gray said. “But you really have to know your body and your cycles. I wouldn’t count on that as a reliable method of birth control.”

Occasionally, a baby may not end up in the correct position for delivery. Its important to know if your baby isnt in the occipito-anterior position right before birth. The exact position of a baby could lead to complications during delivery.
There are some methods you can use to coax your baby into the right position.
You can try the following:
These tips dont always work. If your baby stays in a posterior position when labor starts, it may be because of the shape of your pelvis rather than your posture. In some cases, a cesarean delivery will be necessary.
The More Sex You Have During Your Fertile Days The More Likely You Are To Conceive
This is true. Yep, the more often you have sex during your peak fertile days, the more likely you are to conceive. In fact, couples who have regular sex, which means every day or every other day, enjoy the highest pregnancy rates.
But if committing to this many bedroom sessions isnt possible, or doing it this much doesnt sound like a ton of fun, have sex every two to three days a week starting soon after your period ends.
For men with a normal sperm count, however, having sex more than once a day means that subsequent sessions will offer up fewer sperm. So give yourselves a breather!

Formation Of The Follicle
Each month, from the time of sexual maturity on, about one thousand undeveloped eggs, or oocytes, leave their prolonged resting phase and start to mature. This initiation of development is a continuous process, in marked contrast to ovulation, which occurs only once a month. Once the egg starts to develop, it proceeds inexorably and no longer has the choice of returning to being quiescent. It either wins the race to ovulate or must degenerate and die.
The most striking feature of the eggs development is the growth of its surrounding fluid-filled compartment, called the follicle. The growth of this follicle is stimulated by the hormone FSH , which is produced by the pituitary gland in the early phase of the monthly cycle. The time required for the egg to develop the proper follicle necessary for ovulation is about fourteen days.
Although the FSH stimulates all of the developing eggs during the month to form follicles, one of the eggs always gets a head start over the others, and once it obtains that lead it never relinquishes it. The other eggs developing that month then degenerate. However, if large doses of FSH were to be given to a woman at the beginning of the cycle, far in excess of what her pituitary would normally secrete, she would develop many follicles instead of just one.
Two or three days prior to midcycle, when the follicle has reached its maximum size , it produces an enormous amount of the hormone estrogen.
