In Vitro Fertilization
Donor insemination may be recommended if there are significantly abnormal semen characteristics and if the female appears to be fertile after a series of tests. Causes for male infertility may include irreversible azoospermia (when the male has no sperm), a previous vasectomy, previous radiation or chemotherapy treatment, or an irreversible male fertility factor.
Additional conditions that may require TDI for pregnancy are when the husband or wife or both are carriers of a known hereditary or generic disorder, such as Tay-Sachs Disease, hemophelia, or chromosomal abnormalities. It may also be used if the female has a negative Rh factor and is severely Rh immunized and the male is Rh positive. Additionally, single women who desire pregnancy may request donor insemination.
