Artificial insemination with donated sperm is used when it is not possible to obtain normal sperm naturally from the man, for example when there is azoospermia (there is no sperm production) or when there is a genetic disease on his part and the aim is for the children not to inherit it.
To do artificial insemination with donated sperm it is done from our sperm bank. There, donors and samples go through a rigorous selection process.
First of all, donors must be healthy people, without a personal or family history of genetic diseases, who do not use any type of medication or drug. They are evaluated by a doctor specializing in men, also by a psychologist and a medical geneticist. They are given psychological and genetic tests and tests for AIDS, Syphilis, Hepatitis B, Hepatitis C, Cytomeglaovirus, Blenorrhagia, Chlamydia and HTLV1 and HTLV2 Virus.
Secondly, the semen samples are evaluated to analyze their suitability to fertilize and their ability to survive the freezing/thawing process. They are also quarantined until tests for infectious diseases come back negative a second time.
The selection of the donor to be used is discussed with the couple who chooses the characteristics that best suit their case.
The process of insemination for women begins with menstruation, when she starts the medicines that stimulate her ovary. Ultrasound controls are performed during the course of stimulation and when the woman’s ovary is ready to ovulate, insemination is scheduled.
On the day of insemination, the semen sample is thawed and introduced with a catheter, through the vagina to the uterus, in a painless process that lasts 5 minutes. Fifteen days later, the pregnancy test is performed.
The probability of pregnancy with artificial insemination with donated sperm is similar to the probability of natural pregnancy, which is approximately 20% in one month (one attempt) and accumulated to three attempts, close to 50%.
A different alternative for men with no sperm in the ejaculate (azoospermia) may be to do a testicular biopsy to look for sperm directly in the testicle. These sperm can be used to perform In Vitro Fertilization with Intracytoplasmic Sperm Injection, ICSI.
