If the male have a sperm allergy,low sperm count or poor sperm mobility,artificial insemination can help to conceve.In this procedure the sperm from the male (partner or from a doner) is collected and manually placed in the woman's uterus .An other option is the intrauterine insemination where the sperm is placed directly in the woman's uterus using a catheter,giving the sperm the start in the race to the egg.
If this procedure fails the In Vitro Fertilization is necessary.
In Vitro Fertilization includes five steps:
-Ovarian stimulation:he woman have to take fertility drugs (hormons) from 8 to 14 daysto stimulate her ovaries to produce several eggs per menstrual cycle instead of one.
-Egg retrieval:transvaginal ultrasound aspiration or laposcopic surgery.
-Insemination:it will be choose the most potential egg for pregnancy placed in vitro culture.They will separate the male sperm from his semen and the most "mobile" sperm is added to the egg.
-Fertilization and Embryo culture:from 1 to 5 days the evolution it will be observed ,and in 2-3 days it can be said if the development is normal or not.the embryos can be placed in the uterus from 1 to 6 days after fertilization.
-Embryo transfer:the embryos are transfered to the woman uterus.
