Let's start with a scientific definition. Infertility (Latin - sterilitas) refers to the lack of fertility in women (female infertility) and in men (male infertility).

A little more statistics. In the first year of marriage, pregnancy occurs in 80-90% of women; absence of pregnancy after 3 years of marriage indicates that the chances of its occurrence are decreasing every year. Marriage is considered infertile if pregnancy does not occur for more than two years of sexual activity without the use of contraceptives. Female infertility is observed in 60% of cases, masculine in 40%.

Female infertility can be absolute and relative. Infertility is considered absolute if the woman has deep irreversible pathological changes completely excluding the possibility of conception (absence of the uterus, fallopian tubes, ovaries).
Infertility is considered relative if the cause that caused it can be eliminated.

This division of infertility can be considered to some degree conditional, since some of its forms, previously considered absolute, have now become relative relative to the possibility of in vitro fertilization.

In addition, infertility is divided into primary and secondary. If a woman who has a sex life has never had a pregnancy, they talk about primary infertility. Secondary infertility is the absence of conception after a pregnancy in the past. If conception occurs, but for some reason the pregnancy does not wear out and the marriage remains childless, they talk about one of the types of infertility - miscarriage.
