Hello Thanks for query .You have been trying artificial insemination at home . Normally sperm survival time is one hour after ejaculation .Since you are carrying your friends semen from his place which is 20 miles away it is most likely that all sperms are dead before you reach at home . Second important aspect to be observed is that artificial insemination has to be carried out in a most sophisticated clinic under ideal antiseptic precautions by a qualified Gynecologist during a period of expected and confirmed ovulation . This is something that should not be carried by patient herself at home . Dr.Patil.
