Shettles. The basis for the Shettles method starts with the fact that X-chromosome sperm (femaleFemale sperm can refer to either: A sperm which contains an X chromosome, produced in the usual way in the testicles, referring to the occurrence of such a sperm fertilizing an egg and giving birth to a female. A sperm which artificially contains genetic material from a female.https://en.wikipedia.org › wiki › Female_sperm
Ejaculated sperm remain viable for several days within the female reproductive tract. Fertilization is possible as long as the sperm remain alive — up to five days. Sperm can also be preserved for decades when semen is frozen.
When sperm are inside women's body, they can live for up to 5 days. If you're a man and you have sex even a few days before your partner ovulates, there's chance they may get pregnant.
The Y-chromosome-carrying sperm are said to:
die faster than the X-chromosome-carrying sperm.
For a boy, sperm with the Y chromosome should be deposited as close as possible to the egg because the Y chromosome has a short lifespan and it will not live longer than 24 hours, compared with the sperm with the Y chromosome which will live in a woman's body for up to 72 hours.
The Whelan Method
So if they're hoping for a boy, the theory says, couples can try to have sex four to six days before ovulation. And to conceive a girl, they can hit the sheets either two to three days before ovulation or on the day the woman ovulates.
When sperm are inside women's body, they can live for up to 5 days. If you're a man and you have sex even a few days before your partner ovulates, there's chance they may get pregnant.
Usually, the sperm reaches the egg within 15 to 45 minutes of ejaculation. However, the process could be much longer than that if you haven't ovulated yet by the time you have sex, because sperm can live inside a reproductive tract and wait for an egg for up to five days.
Age of Sperm and Survival of the Pregnancy
Only 6 percent of the conceptions could be firmly attributed to fertilization by sperm three or more days old.
The researchers found it is likely the strongest sperm survives but merely because the egg chose to have that happen. "When sperm go into the follicular fluid, they start to go straighter and they start to change the way they swim.
You ovulate about 12 to 14 days before the start of a new menstrual cycle. Your fertile window is the five days leading up to ovulation, plus the day of ovulation and the day after ovulation — so about seven days in total.
There are few persons who believe that, the ovary of the right side yields ova which on fertilization develop as males, and the ovary of the left side yields ova which are potentially female but it is not scientifically proven. Development of female or male child depends on chromosome (X or Y) from father's sperm.
There is no specific frequency with which a man should ejaculate. There is no solid evidence that failure to ejaculate causes health problems. However, ejaculating frequently can reduce the man's risk of getting prostate cancer. Ejacu-lation can be through having sex or masturbating a few times a day.
Loss of seminal fluid after intercourse is perfectly normal, and most women notice some discharge immediately after sex. Many infertile couples imagine that this is the cause of their problem.
When you are most fertile. The 5 days before ovulation, together with the day you ovulate, are the days when you are most likely to conceive. Sperm can live up to 5 days inside your body, so if you have sex up to 5 days before your egg is released, you can get pregnant.
How many times can a man ejaculate in a day? Some men can ejaculate more times during the day than others. Younger men tend to ejaculate more often than their older counterparts. Some men can ejaculate (or come) once or twice a day, whereas some guys can do it four or five times.
Once inside the body of a woman, a healthy sperm can live up to 2-5 days. Once the sperm reaches the released egg, it does not mean that it is capable of fertilizing it immediately. The sperm will then undergo a process called capacitation in the reproductive tract. This process will take about 10 hours.
Only 1 in 14 million of the ejaculated sperm will reach the Fallopian tube, but once there the sperm should pick up chemical signals from the egg to help them find their way forward. The sperm finally near the egg and push towards its shell (called the zona pellucida).
If your menstrual cycle lasts 28 days and your period arrives like clockwork, it's likely that you'll ovulate on day 14. That's halfway through your cycle. Your fertile window begins on day 10. You're more likely to get pregnant if you have sex at least every other day between days 10 and 14 of a 28-day cycle.
4. Lay down and relax for a few minutes after sex. Standing up or going to the bathroom after sex may pull sperm away from their destination. So, lying on your back for 15 minutes or so after sex may help keep sperm moving in the right direction.
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.
Studies show that the average length of time that sperm live, once ejaculated or inserted into the female reproductive system, is around three days. This depends on where she is in her menstrual cycle, however—with just the right timing, stronger sperm could last up to five days.
Have sex regularly. The highest pregnancy rates occur in couples who have sex every day or every other day. Have sex near the time of ovulation. If having sex every day isn't possible — or enjoyable — have sex every 2 to 3 days a week starting soon after the end of your period.
A man might have watery semen if he doesn't get enough zinc in his diet. Zinc is an important nutrient for sperm production. Men who ejaculate several times a day might also develop watery semen, since the body needs time to “catch up” on its semen production.
