Sperm donation and rhesus incompatibility

Share Button
Remember: Blood type compatibility can have a huge impact on your pregnancy and with that, the well-being of your future child. Blood type dating is designed to help rh negative women who are still single, meet and befriend rh negative men.
Love comes from all angles and who is right for you, isn’t to be decided by anyone other than you. What we do believe in is giving rh negative women who want to filter potential partners based on rh factor, the option to do so.

Children conceived through sperm donation have a birth defect rate of almost a fifth compared with the general population. This may be explained by the fact that sperm banks only accept donors who have good semen quality, and because of the rigorous screening procedures which they adopt.

In addition, sperm banks may try to ensure that the sperm used in a particular recipient woman comes from a donor whose blood group and genetic profile is compatible with those of the woman.

Sperm donation is also used in cases of rhesus incompatibility. This particularly occurs where a woman is rhesus negative, and her partner is rhesus positive. The woman’s body may reject a foetus if it has rhesus positive blood. Anti D injections have been developed and may be used to attempt to avoid this, and these are usually automatically given to rhesus negative women immediately after they give birth to their first child. However, in the past this was either not possible or was not always routinely undertaken where a woman had gave birth or had an abortion and she may have trouble carrying a child later in life. Furthermore, for some women, the anti D injection does not provide the entire solution, particularly where there is a medical history of complications during pregnancy which risk the woman’s blood and that of the foetus becoming mixed. In such cases, sperm from a rhesus negative donor can provide the solution and a woman may be able to conceive and carry a pregnancy to full term when otherwise this would not be possible. For this reason, sperm from rhesus negative sperm donors is often in great demand, particularly those with the O negative blood group who are universal donors.
