There should be no history of hereditary disorders or specific metabolic diseases in their own family. These include:
Precisely because of the risk of infection associated with promiscuity or a high-risk lifestyle, men from certain groups are not accepted as donors (drug addicts, homosexuals).
Donors are tested for the following infectious diseases:
Each new donor undergoes chromosomal testing (a karyogram). Under certain circumstances, other tests (such as molecular genetic testing) may also be performed.
Each sperm sample is only released for use after 6 months of quarantine and after a repeat physical examination reveals no significant findings. This period is based on the so-called incubation period, which can be a few months for HIV pathogens. HIV antibodies are in some cases only detectable in the blood a few months after infection.
The often large number of different donors of all blood groups permits the couple to select a donor with the desired characteristics, which will in most cases understandably match those of the husband/partner. These include general outward characteristics such as physical appearance, hair and eye colour, etc., as well as blood group and Rh factor.
Donors are classified according to level of education, profession and interests. It is therefore possible in some circumstances to consider personal characteristics and education.
The photographs of donors held by the Berlin Sperm Bank (Berliner Samenbank) are not provided to the recipient couple as this would violate the donor's desire for anonymity. However, the photographs give us the opportunity to achieve the best possible match between donor and partner.
We usually provide the couple with an initial selection of donors in the form of a list with four to eight potential candidates, with the visual "match" between the appearances of the sperm donor and partner/husband also quantified (1 = very high; 2 = good similarity).
Should three to five treatments under optimal conditions with the samples from a donor not result in pregnancy, it may be advisable to change donors.
Of course, this also applies if all of the samples from this donor have been used up in the meantime. It may therefore be highly advisable to reserve a specific number of samples in advance (for an additional cost).
