Why do women get pregnant even when they use contraception?

Women who get pregnant during their time using contraception may have a genetic variant that breaks down hormones aimed at preventing conception, and a study carried out for the first time.

This study is the first to discover that a gene can interfere with the prevention of pregnancy, perhaps giving a mystery of why a number of women become pregnant each year even while using contraception.

Find CYP3A7*1C, although active in all fetuses, is off on most adults but a small number of people are on fire.

According to the publication, this gene can filter down hormones labeled by the means of pregnancy control.

Furthermore, it can appear in the genetic test.
