What is the probability of multiple pregnancy in donor artificial insemination?

By Andrea Rodrigo B.Sc., M.Sc. (embryologist).

During artificial insemination, the woman receives hormonal treatment to stimulate ovarian production and control the exact moment of ovulation. For this reason, the probability of multiple gestation is higher in relation to natural pregnancy.

For this reason, it is important to adequately monitor ovarian development and cancel insemination in case of risk.

The probability of a multiple pregnancy in artificial inseminations with donor sperm is approximately 8% in women over 40 years of age and 12% in women under 40 years of age. In any case, although the risk exists, the process is carried out in such a way that the probability is reduced to a minimum.

The origin of the semen sample does not affect, as the probability of having twins or triplets is the same in donor AI as in conjugal AI in the case of women under 40 years of age (which is the most common in the AI technique).
