Virgins can also become pregnant

　　A girl didn't have her period, so her mother went with her Gynecology After the examination, the girl insisted that she had never had sexual intercourse. Her mother also said that her daughter was an excellent high school student and only knew how to study. After the examination by the obstetrician and gynecologist, he found that the girl had never had sexual intercourse, so he had to find another reason for diagnosis and treatment.

　　Another month later, not only did my period not come, but the signs of pregnancy were obvious. After further questioning, I found out that the girl and her boyfriend were too intimate. Although there was no real sexual intercourse, they had had sex outside the body. ejaculation , in fact, this is not a fantasy. The gynecologist said that she has encountered more than ten cases of teenage pregnancy with intact hymens.

　　Why does in vitro semen pregnancy occur? You know, a man excretes 200-300 million pieces of semen at one time. sperm . Semen can be ejaculated up to 50 centimeters, and sperm can run 65 kilometers in one hour. It takes 1.5 to 3 minutes for sperm to enter near the vagina Uterus cavity, and the fallopian tube can be reached within 30 minutes. Sperm can live outside the body for 24 to 48 hours.

　　From a physiological point of view, teenage girls have the most vigorous reproductive function. As long as there is ovulation, the pregnancy rate is also the highest.； During sexual excitement, vaginal secretions can flow outside the body and mix with semen. Sperm swim along the mixed fluid into the vagina, cervix and uterus. At this time, the egg coming from the fallopian tube will be fertilized. If the semen ejaculated outside the body remains in the woman's vagina and is not washed immediately, the sperm can survive easily in a warm and humid environment, which is also the reason why pregnancy may occur.

　　From this point of view, pregnancy is still possible without direct sexual intercourse and ejaculation outside the body.
