The studies concluded that fewer male babies were conceived during the peak ovulation time. Instead, male babies tended to be conceived in “excess” 3 to 4 days before and in some cases 2 to 3 days after ovulation.
On the other hand, having sex from 2 days before ovulation, through a few days after ovulation, is better for conceiving a boy. Around the 2-day point, 48 hours before ovulation, seems to be the 50/50 mark. (2) The pH of the women's tract is also very important.
Getting pregnant after ovulation is possible, but is limited to the 12-24 hours after your egg has been released. Cervical mucus helps sperm live up to 5 days in a woman's body, and it takes around 6 hours for active sperm to reach the fallopian tubes.
Speed: since sperm containing the Y chromosome are faster than those containing the X chromosome, if the egg is in the fallopian tube at the time of intercourse, there is a greater probability of a Y sperm reaching and fertilising it, which means there is a greater probability of the baby being a boy.
The key to conceiving a boy is to do “the deed” close to your ovulation. As Dr Shettles points out, male-producing sperm (Y-chromosome) move faster than female sperm. Male sperm also dies pretty fast, while female-producing sperm (X-chromosome) can stick it out and take their time hooking up with the egg.
Once ovulation occurs, your egg travels through your fallopian tube. It's in your fallopian tube that your egg meets sperm for fertilization. If conception occurs (sperm fertilizes your egg), the fertilized egg travels down to your uterus.
Within 24 hours of ovulation: Sperm fertilizes an egg (conception occurs). About six days after fertilization: The fertilized egg implants into your uterine lining. Around day 21: If conception and implantation occurred during this menstrual cycle, you're pregnant.
A pregnancy test can detect pregnancy before a woman misses her period, but some may notice symptoms even earlier than this. The first sign of pregnancy is often a missed period, which happens around 15 days past ovulation (DPO).
The Egg Travels to the Fallopian Tube
After the egg is released, it moves into the fallopian tube. It stays there for about 24 hours, waiting for a single sperm to fertilize it. All this happens, on average, about 2 weeks before your next period.
A released egg lives for less than 24 hours. The highest pregnancy rates have been reported when the egg and sperm join together within 4 to 6 hours of ovulation.
Nature is designed to favour the conception of boys from September to November and girls from March to May because of an evolutionary mechanism aimed at keeping the overall sex ratio as near to 50:50 as possible, the scientists said.
At a minimum, have sex every other day during the fertile period (the week to 10 days after ovulation). It takes one to two days for sperm to regenerate, and you don't want it to be older than four to five days.
At 3 DPO, a mature egg has been released by the ovary and has traveled through the uterine tube. An egg typically stays in the uterine tube for the first 12–24 hours after being released by the ovary until it's either fertilized or reduced. This is why there is a short window for fertilization.
within 24 hours of ovulation, the egg is fertilised by sperm if you have had sex in the last few days without using contraception. about 5 to 6 days after ovulation, the fertilised egg burrows into the lining of the womb – this is called implantation. you're now pregnant.
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.
According to Shettles, timing sex as close to or even after ovulation is the key to sway for a boy. Shettles explains that couples trying for a boy should avoid sex in the time between your menstrual period and days before ovulation. Instead, you should have sex on the very day of ovulation and up to 2 to 3 days after.
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.
Every egg has an X sex chromosome; a sperm can have either an X or a Y sex chromosome. If the sperm that fertilizes an egg has an X chromosome, the baby is female; if it has a Y chromosome, the baby will be a boy.
Take fertility medicine and folic acid supplements. Both of these things can positively influence your odds of having twin boys. They can also encourage hyperovulation. Overall, you (and your partner, of course) should take good care of yourselves, avoid stress (if possible) and harmful substances.
Yes, you can get pregnant after ovulation, as long as you have sex within about 12 to 24 hours of when an egg was released. The fertile window can last 5 to 6 days, from the 5 days before ovulation to the day of ovulation.
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.
With this knowledge, you can conclude your highest fertility window, which is about 3 days before, after, and during ovulation. However, you're also fertile 5 days before and one day post ovulation. You can also use the cervical mucus method to assess your fertility.
