Professor Adam Taylor, of the University of Lancaster, explains in The Conversation that the human body sometimes reserves surprises. He evokes four exceptional circumstances that led to a pregnancy, without classic vaginal relation: an anal relationship, an oral contact, a simple semen splash, or even a pregnancy already in progress.
Anal report and anatomical anomaly
The first scenario mentioned concerns a pregnancy which occurred after an anal report. This phenomenon is made possible by a rare malformation, called cloacal malformation, which affects approximately one woman in 50,000. This anomaly creates a communication between the rectum and the vagina, allowing sperm to migrate and reach the ovum. Fertilization can then take place, and pregnancy takes place normally in the uterus.
A pregnancy after blowjob?
A particularly surprising case was published in the British Journal of Obstetrics and Gynacology. It concerns a 15 -year -old teenager living in Lesotho, southern Africa. Born without a vagina because of a Mullerian Agenesis, she consults for abdominal pain, and the doctors discover that she is pregnant.
How could it happen? Nine months earlier, she had practiced blowjob to her partner. Drupted suddenly by a former jealous boyfriend who stabbed her in the belly, she was hospitalized. The sperm would then have entered the body via the injury, fertilizing a egg. The girl later gave birth to a healthy baby, by Cesarean.
When a splash is enough
Pregnancy can also start without sexual intercourse, simply by external contact. If sperm comes into contact with women’s genitals, some sperm can go up to the uterus. This type of pregnancy remains extremely rare, because the sperm survive very little time outside the body, about thirty minutes, and move at a speed of 5 mm per minute. In this case, we could almost talk about “super sperm”!
One pregnancy … then another
Finally, an equally rare phenomenon: superfection, or double pregnancy. Normally, once pregnant, the body prevents any new ovulation. But it happens that this mechanism does not work, especially during in vitro fertilization protocols. Result: two embryos designed a few weeks apart grow in parallel and are born together, like twins.
Professor Taylor wishes to reassure: “These examples are of course extremely rare” and add: “So you don’t need to worry”. However, it concludes with essential advice: “If you are not trying to get pregnant anytime soon, be sure to use contraception.”
