The 3 to 7 days that menstruation lasts is called the menstrual period.
In most women the menstrual cycle is about 28 days, but it can vary considerably even from one month to another.
Hence, let us assume we have a 30-days chart, Day 1 on the Chart will be the 1st day of the woman's menstruation.
PERIOD.
Between 13th and 14th day after the menstruation, the ovary releases the mature egg in a process called ovulation.
The egg passes through the fallopian tube to the uterus.
If the egg unites with a sperm on its way to the uterus, fertilization occurs and pregnancy ensues.
However, to conclude our research here by driving the point home again with reference to our past study: If you desire a baby boy: We know that the 'male' sperm cells, which carry a Y-chromosome, swim more quickly than the 'female' sperm cells, which carry an X-chromosome, but will die off faster as well, so the twoof you as partnersmust be sure that you are as close to 100% certain that you are ovulating, then you can have sex closer to that ovulation date.
This is to allows the faster swimming 'male' sperm to swim off to the waiting female egg and fertilize it before the slower swimming 'female' sperm reach their destination.
The result will surely be a bouncing baby boy.
On the other hand, if you want a baby girl: then the best bet is to make love at least two days before you ovulate (i.
e.
day 9, 10 and/or 11), as this will allow the faster swimming 'male' sperm to swim off, burn up their energy and die off, leaving the slower swimming ''female' sperm to arrive to a ripe and ready female egg that is still waiting to be fertilized.
Hence, you are sure of conceiving a baby girl.
However, there are some other factors to be considered such as: Positioning of the couple during sex The diet The vaginal acidity environment etc.
