Sperm Bank

The sperm bank is a fundamental resource for assisted reproduction because 30% of couples’ fertility problems are due to male factors.

What is a Sperm Bank?

Sperm donation is anonymous, voluntary, and altruistic. It involves a young man with good semen quality donating his sample to the bank so that patients who need assisted reproduction treatments can use it.

Many patients also inquire about sperm cryopreservation, which involves freezing sperm to preserve male fertility, similar to the oocyte vitrification technique performed for women. Sperm cryopreservation allows the donor’s sample to be stored in the bank for later use in assisted reproduction techniques. This preservation technique does not affect the quality of the sample and has no storage time limit.

How does it work?

You can use the Sperm Bank without any additional medical preparation. If you do not have a male partner or the male partner has a severe infertility factor, the sperm bank is necessary for all of these reproduction treatments:

Who should use a sperm bank?

  • Male with severe male factors, such as azoospermia (absence of sperm in semen).
  • Male with a dominant hereditary genetic disease without the possibility of preimplantation genetic diagnosis.
  • Male carrier of a genetic disease that cannot be studied in embryos.
  • Serodiscordant male.
  • Repeated fertilization failures with partner’s semen.
  • When poor embryo quality or implantation failure has been obtained in previous cycles, and a male factor is suspected as the main cause.
  • Single women or women without a male partner.

Documents and analysis

To use the sperm bank, the requesting patients must provide the following documentation:

  • Previous medical and gynecological history.
  • Report of assisted reproduction treatments carried out in other centers, if applicable.
  • Updated serologies for hepatitis B, C, syphilis, and HIV-AIDS.
  • Blood groups and Rh.
  • Complete and sign the request and informed consent corresponding to the assisted reproduction treatment with donor semen.

What studies are done on the donor?

As stipulated by the Law on Comprehensive Access to Procedures and Techniques of Medically Assisted Reproduction, gametes must come exclusively from gamete banks registered with the Federal Registry of Health Establishments (ReFES) of the National Directorate of Health Regulation and Quality in Health Services, dependent on the Ministry of Health.

The sperm bank samples used by WeFIV come from men between 18 and 40 years old, with good general and reproductive health:

  • They undergo a psychological evaluation.
  • Registration of blood group and blood factor is assessed.
  • Genetic diseases and transmissible infections are analyzed with semen, blood, and urine samples.
  • A follow-up is carried out from 6 months to 1 year to ensure the health of the sample.

All of the above steps are completed to guarantee all our patients a quality sample, taken with professionalism and all the necessary care. Each of our treatments is personalized and adapted to the needs of each patient. Even the donor’s physical characteristics are considered so they are compatible with the couple requesting the sample.

Frequently Asked Questions

Sperm can remain indefinitely in a sperm bank, thanks to a process called cryopreservation. This method consists of freezing the sperm to preserve the fertility of the man, similar to the technique of vitrification of oocytes performed by women. This preservation process does not affect the quality of the sample and does not have a conservation time limit.

Yes, it is possible to choose the sperm donor, but there are certain restrictions. Sperm donors must be young men in good general physical and reproductive health, who undergo a series of studies and analyses to guarantee the quality of the sample. In WeFIV, in addition, the physical characteristics of the donor are taken into account so that they are compatible with the patients requesting the sample. However, it should be clarified that sperm donation is anonymous, so the identity of the donor cannot be known.
