* The donors’ selection
A first specimen of semen will be examined on the microscope, where the quantity and the mobility of spermatozoa will be observed. Subsequently, the microscopic analysis will be repeated on a new specimen, and if this one is successful, a freezing test would be carried out. Then, the specimen will be unfrozen and the survival to freezing will be checked. If it is acceptable, then it will be proceed to carry out the blood and semen cultures and finally the donor will be called for the next donations.
* When should you stop being a donor?
• When the donor voluntarily decides so and also in the following cases:
• When the quality in the semen in repeated specimens does not allow its freezing or when, after freezing, survival is not acceptable.
• When anomalies are detected in the analysis that are carried out periodically.
• When the number of gestations established by law has been achieved with semen of one particular donor and the bank does not intend to use this semen in diagnostic tests.
Furthermore, before a man can become a sperm donor he must undergo testing for sexually transmitted diseases (STDs) as well as drug use. A specimen will also be provided to the clinic so that it can be analyzed by their doctor as well. Usually, it will be quarantine phase during which time the sperm cannot be used, so that it can undergo further quality testing.
If it is approved, it sill generally be required to enter into a contract with the donor clinic for a period of six months to two years.
For the anonymity of the donor, unless you choose a man you know to become your sperm donor, you will not be entitled to any information about him. According to the HFEA, the identity of the sperm donor cannot be revealed to the recipients, though his physical characteristics, blood group and other pertinent information can be told in order to help find the most suitable match. In the same way, the donor is also not permitted to receive information about the recipient. Also a donor does not have any parental rights to any children born from his sperm.
Nevertheless, by reason of increasing interest around the identity of sperm donors, national registries have been set up to help children born of these donors, find a match.
* Risks of Using Donor Sperm
Concerning physical risk, the most significant one associated with sperm donation is infection. This concern appears when dealing with known donors, as they are generally not required to undergo the same extensive testing as anonymous donors. It is critical that you ensure any potential sperm donor undergoes rigorous testing.
Though, generally great concern for couples choosing sperm donation is the potential of legal complications. Anonymous donors are required not to insist on any legal rights; this can become an issue for those who use known donors. No matter the case, it’s important to draw up a legal contract that outlines exactly what your wishes are with respect to this issue.
