Sperm freezing

The first sperm bank in Spain was organized by Dr. Simon Marina, andrologist Cefer Director of the Institute in December 1977. The semen is frozen in liquid nitrogen at 196 degrees below zero. The container which preserves the sperm tubes is what is called Sperm Bank.

The frozen semen can come from an anonymous donor who donated his sperm to help couples or women to bear children. It is the most frequently used in the Institute .. Cefer can also come from a man who wants to preserve their sperm for later suus for different reasons and treatments that could destroy their fertility or before a vasectomy.

In the 30 years of the sperm bank has more than 3000 children born.
The donor semen freezing is required, under Spanish law .. You may not use fresh sperm from anonymous donor.

Other Applications of the Sperm Bank
Patients’ own sperm is also frozen at the Sperm Bank before they undergo a vasectomy, prostrate surgery, radiotherapy or chemotherapy which may leave them sterile. In this case, the frozen sperm is not used for donation, but rather to preserve the patient’s own fertility.

Another reason to freeze patients’ sperm is for the IVF-ICSI process with donated eggs, in order to avoid a meeting between the egg donor and the recipient’s husband.
A patient’s sperm is also frozen if it is anticipated that on the day eggs are going to be extracted from his wife, he will not be able to provide sperm, due perhaps to his having to work or to a psychological block that prevents him from ejaculating. The andrologist will tell him if freezing sperm is necessary or advisable in his case.

Sperm can remain frozen for years, maintaining its potential for egg fertilisation.
