It is possible to get pregnant even if the hymen is not broken for the following reasons: a. The hymen itself has holes to facilitate the flow of menstrual blood every month; b. The hymen hole has various shapes, including round, oval, serrated, sieve, etc. Some women have larger hymen holes and good elasticity, and there is the possibility of multiple sexual intercourse without rupture; c. There are also women with thicker hymens or less vascular, which can also be used during sexual intercourse without rupture Therefore, regardless of whether the hymen ruptures and bleeds during sexual intercourse, as long as the man ejaculates into the vagina or even at the vaginal opening, the sperm enters the fallopian tubes through the vagina and uterus, and if it happens that the woman is ovulating, the combination of sperm and egg will make pregnancy possible. Therefore, women must do a good job of contraception before they are ready to become mothers and should not take any chances.
