How does the possible sex of the child change according to the ovulation?

So, the egg of a woman and the sperm of a man contain a single set of chromosomes. This means that the female organism (XX) transfers to the future descendants the set X, and the male (XY) – either X or Y.

The sex of the future child depends on which particular kind of sperm, “male” (Y) or “female” (X), the egg meets.

To conceive a girl, you need to plan actively no later than 2 days before ovulation occurs.

And now the most interesting thing!

X and Y spermatozoa have differences. And by knowing them, it will become easier to predict when to make love and become pregnant with a girl.

Female and male spermium under a high resolution microscope. Female’s are larger and slower. Male’s are smaller and faster

X-spermium:

– are more vivacious (up to three days, rarely up to seven days);

– are larger and heavier;

– move slower.

Y-spermium:

– are more active and mobile (speed 0.1 mm / sec.).

Get to the Fallopian tubes already 1-1.5 after the sexual intercourse;

– are smaller and lighter;

– deplete and die faster (live mostly up to 24 hours).

The egg also lives up to 24 hours. Hereof it follows that the more time (but not more than 3 days) that elapses from sexual intercourse to ovulation, the more likely it is to become pregnant with a girl. This is because only girl spermatozoa will survive.

How to calculate the day of ovulation to conceive a girl

If the menstrual cycle is regular it’s not difficult to calculate the day of ovulation (DO). Subtract 14 from the number of the days in the cycle. If you want to find out the day of ovulation as accurately as possible, determine the duration of your own luteal phase.

Then subtract the duration of your second phase of the cycle from the days of the cycle instead of 14. It is constant for the same woman. In this case, it’s necessary to plan the conception of a girl in accordance with ovulation, as follows: after menstruation occurs, it’s necessary to plan actively every two or three days and to stop two days before ovulation.

For example, if the duration of the cycle is 30 days, then the duration of the II phase is 13 days. Then the day of ovulation is – 30-13 = the 17th day of the cycle. It’s better to stop open contact on the 15th day of the cycle. There can be such combinations:

How to calculate ovulation in cases of an irregular cycle?

The best ways to find out the date of ovulation for planning a girl will be:

Folliculometry, when the doctor says that ovulation will occur according to the growth rate of the dominant follicle;
Tests for determining the jump of LH. In this case it’s necessary to continue sexual intercourses until the test gives positive result;
Tests for crystallization of saliva. They are based on determining the amount of estrogen in saliva. The higher estrogen – the more crystals resemble a fern leaf;
Observation of the state of health. Self-observation method works only if there are any signs and sensations before ovulation.

Note (!): Tests for crystallization of saliva are somewhat laborious. But they are convenient in that if you catch the nature of the change in the form of saliva crystals two days before ovulation, it will be simple for future cycles. As soon as a characteristic change has occurred – it will be known for sure that the ovulation is in 2 days.

If the sex occurred the day before ovulation – who will be born, a boy or a girl?

If the sexual intercourse occurred the day before ovulation, it is possible to conceive both sexes of a child with the probability of 50×50. At the time of ovulation, both female and male spermatozoa will come in to the fallopian tubes.

Who will be born if ovulation has already occurred and intimacy was after? In this case there will be a boy. Read more about the method of conception of a boy by ovulation in this material on ovulationdiary.com.

Have a successful planning!
