<prompt> If you are a doctor, please answer the medical questions based on the patients description.I ve read many, many replies on many websites from doctors regarding the chances of getting pregnant by a small amount of ejaculant on one s hands being rubbed onto the vaginal opening. Some simply say yes, possible bc it only takes one sperm , while some say It s highly unlikely , etc. What I d like to know is: 1 Is there any medical professional here who actually knows of a case of pregnancy happening from such a situation? and 2 are there any more scientific studies on this? Thank you.  <response>: Hello, thnks for trusting Chat Doctor doctors for your health related queries.I guess your concern is-probability of getting pregnant in this kind of scenarios n any scientific studies on these???lets discussion part by part...well lets have short discussion about semen n sperm...semen is that white lotion thing what guys ejaculate.in this lotion small sperms will be there, which meet ovum n women beams pregnant...semen is sticky in nature...imagine u have had a very oily food,even if u wash with soap water still u can feel that sticky nature for sometime.same way semen is...it is sticky in nature...with this sticky nature of semen, it will be sticking to the part of vagina where ever its been rubbed,thereby sperm too...so this sperm may meet the ovum present inside vagina and women becomes pregnant...usually success rate of pregnancy increases when men ejaculate inside the vagina...this is the usual norm...however medical field is know for many miracles...this small amount of sticking semen can also cause pregnancy...but chances are very, very minimal...whatever replies u have come across online it seems to be correct...no one can pinpoint n say pregnancy is possible or not possible...1.is there any medical profession:as such separate departments are not available to judge in these special scenarios as u he told above.generally its obstetric n gynecology dept that deals with pregnancy n infertility.2.are there studies:there may be present...fr that u need to access scientific journals of medical fields...I hope this was informative enough, n useful for your query.regards: Chat Doctor. .usually a woman can pregnant after 12-13yrs when her menses start...n a woman cant become pregnant after 50yrs,as her menses stop...but there its been reported the oldest women to pregnant is approx ABV 60yrs n the youngest women approx 10yrs...wanted to give example to say medical world is known for miracles!!!-
