Pregnancy twins: how and why does this happen?
Pregnancy is the happiest time for the fairer sex. Sometimes it happens this way: after examination and ultrasound, the doctor reports that the patient has multiple pregnancies. What does it mean? This indicates that two fertilized ovules were found on the ultrasound monitor, which means that this pregnancy is a double. There is rarely a triple pregnancy, but this is another story.
Double conception can occur in two situations:
- When two active ovules are fertilized at once
- When dividing one egg into two embryos
The main factor in influencing the conception of twins is, first of all, heredity. If cases of such pregnancy are known in the genus, then the appearance of conception in the offspring is not excluded. Also, such factors include the age of the woman, the method of fertilization and the procedure for treating infertility. The age of a woman older than 35 years causes the emergence of multiple births as a result of the accumulation of hormones. Extracorporeal conception can also manifest as a double pregnancy. Treatment of infertility is another factor that causes pregnancy of twins, since drugs contain a large number of hormones that affect not only the possibility of conception, but also the appearance of two embryos.
