To date, there are several options for planning the sex of the unborn child. Their effectiveness is different, as is the time in which they were developed. Among all the most scientific is the method of planning the sex of the child for ovulation. It is a calculation of the most favorable days and conditions for the conception of a child of one sex or another.
The method of determining the sex of the child by ovulation is due to L. Schettles and D. Rorvik, and we will consider it in detail.
What determines the sex of the child?
The sex of the unborn child depends on the chromosome set of the spermatozoon, which was the first to reach the ovum. If it was a spermatozoon with an X-chromosome, then there will be a girl, and if with a Y-chromosome, then the parents will babysit the boy. Knowledge of this fact prompted scientists to address the issue of gender planning of the baby. According to their theory, there are several indirect factors, the consideration of which during the period of ovulation will help to calculate the sex of the unborn child.
To such factors, scientists from the American Institute attributed:
- reaction of the vaginal environment;
- motility of spermatozoa.
Also, the probability of conceiving a child of the desired sex increases with the use of certain poses during sex.
How to conceive a boy?
Spermatozoa with a male set of genes are more mobile in comparison with their "X-brothers". Especially comfortable with them in the alkaline environment of the vagina, while in the acid reaction of the environment they quickly die. Increase the chances of the appearance of a boy, you can have sex in one day or on the day of ovulation. It is advisable to use poses with the deepest penetration of the penis into the vagina.
How to conceive a girl?
Planning parents of a child by the female method of calculating ovulation, involves having sex two or three days before the release of the egg. Sperm mobile spermatozoa with X chromosomes are more viable than cells with a set of Y chromosomes. Provided that the posture during sex was missionary, the chances of the girl's appearance are higher. It is desirable that a woman does not experience orgasm, because after it the reaction of the environment of the vagina changes to alkaline.
Definition of ovulation
Determine the days of ovulation can be by careful observation of a woman at the basal temperature of her body for several months. When ovulation occurs, the temperature rises to 37 degrees.
Observation of changes in temperature for several months can give a relatively accurate picture of the onset of ovulation. Additionally, you can use special tests to determine ovulation.
Constant monitoring can help to compose your own ovulation calendar, according to which it is possible to plan the sex of the child. It should be remembered that this method does not relate to reliable by 100%, because it is suitable for permanent and accurate menstrual cycles. The risk of shifts is present in these cases, it is caused by stresses and diseases.
