When to give birth?
When to give birth children?Sometimes women and doctors opinions are diametrically opposed.
It is believed that the man in your life has to do three things: build a house, plant a tree and raise a son.The main purpose of the woman - to give birth and raise children.In recent years, young people are more passionate about education and career.And more and more women prefer to give birth after 30 years.
However conceive at this time is much more difficult than it seems at first glance.The fact is that with age the supply of eggs in the ovaries (called the ovarian reserve) has been steadily declining.And the older the woman the lower her chances of getting pregnant.
The most important
Ovarian reserve (synonym - ovarian reserve, follicular reserve) - the number of "dormant" follicles in the ovaries of women.Speaking the language of sport is - bench.In each menstrual cycle follicles of these come into play - they begin to grow.But only one eventually begins to lead and reachingthe size of 18-20 mm, is ovulating.Growing in the egg after ovulation it can be fertilized by sperm, and with luck, is implanted in the uterus, giving birth to new life.The remaining follicles, before reaching the finish line, regress.
optimal time to give birth
The ovaries in girls, being in the womb, there is 7 million follicles.
But when the girl starts menstruating, they make only 300-400 thousand.Only 1% of the total number of follicles having passed a long way of natural selection, it is ovulating.
After 35 years, the number of follicles in women is declining rapidly.When it comes to the thousand, natural menopause occurs.
successful pregnancy depends on the natural fertility (ability to conceive).The highest chance of conceiving children - healthy women from 20 to 25 years.It is this age is optimal for procreation.
With 25 years the possibility of natural conception and reduced to 40 years reached only 5%.reasons for the decline of ovarian reserve:
- hereditary syndrome of premature depletion of ovarian function;
- surgery on the ovaries.
How to diagnose decrease?
ultrasound.The study calculated the volume of the ovaries, count the number of antral follicles.
Determination of blood levels of hormones: follicle-stimulating hormone (FSH) and luteinizing hormone (LH) in the first phase of the cycle (2-3 days).
There is a direct relationship between the level of these hormones and follicular reserve.Elevated levels of FSH - the first sign that the number of follicles on the wane.
Determining the concentration of inhibin-B and antimyullerova hormone.Unfortunately, these parameters determine experimentally only in Russia.
What to do if the stock is reduced?
In each case, the problem is solved individually.If indicators of follicular reserve allow IVF program is conducted with the use of stimulant medications.However, the efficiency of the IVF program in this case is quite small - about 15%.
There is a second option - egg donation.However, it may decide not to everyone.
Typically, egg donors are young healthy woman.Subsequently, their sperm fertilize the patient's husband.The resulting embryos are genetically alien, but pregnancies generally progressing normally and the female patient has to the biological mother of the child.
In conclusion, we want to advise - it is better to have children up to 30 years.After all, in this age of follicular reserve is usually normal, and other people's intervention is not required.
