There is a possibility of pregnancy if normal sexual intercourse takes place, even if the hymen is not ruptured. There are two main possibilities for this to happen: the first is that a woman’s hymen is very elastic, so she has normal sexual intercourse and her hymen is not ruptured. In this case, the male penis has entered the woman’s vagina and ejaculation, sperm can enter the uterine cavity, fallopian tube, and the egg will meet, there is a possibility of fertilization; second, the male penis did not completely enter the female vagina, just in the female vaginal opening ejaculation. In this case, the sperm can also enter the female vagina under the pressure of ejaculation, and then pass through the female cervix, the uterine cavity, and enter the fallopian tube to meet with the egg, so as to achieve the purpose of fertilization. Therefore, pregnancy is possible in both cases, and it is not based on whether the hymen is broken or not as a criterion to determine whether the patient is pregnant or not.
