Patients of the Center
There are several reasons why a patient undergoing assisted reproductive treatment should freeze a sperm sample: patients with very poor sperm quality, or those who have difficulty obtaining the sperm sample, therefore, their sperm sample is frozen to make sure that on the day of treatment we will have sperm in order to microinject into the eggs of their partner; oocyte donation patients; men who may not be available the day of egg retrieval due to their working schedules; patients who undergo diagnostic testicular biopsy or epididymal aspiration; etc.
Among men who want to preserve their fertility for the future are those who will undergo chemo or radiotherapy, those who will undergo vasectomy, or those who simply want to freeze sperm for the future.
All sperm donors are required to undergo a sperm quality study. Only those that have a high quality sperm sample are admitted. Once they have completed the first phase, we will make a detailed personal and family medical history, in order to rule out hereditary diseases. They undergo a complete blood test to rule out sexually transmitted diseases as HIV 1 +2, Hepatitis B, Hepatitis C, Syphilis, Cytomegalovirus and Chlamydia. Also a genetic analysis by determining the karyotype to detect the presence of genetic diseases is performed.
The donor’s sperm is mainly used for:
• Infertile couples, when the husband has no sperm (Azoospermia), both in the ejaculate and in the testis and/or epididymis.
• Couples with severe male infertility factor and it is not possible to perform in vitro fertilization with intracytoplasmic sperm injection (ICSI).
• Single women.
• Couples with the possibility of male’s genetic disease transmission, which can not be ruled out by means of preimplantation genetic diagnosis.
