Sperm can either be provided by the partner –Artificial insemination with partner sperm (AIH)– or from a sperm bank –Artificial insemination with donor sperm (AID)-. The semen is prepared in the laboratory, where mobile sperm are separated from the other components (seminal plasma and other cells). To increase the chances of a pregnancy, the ovaries are stimulated with hormones and ovulation is monitored to ascertain the best time to carry out the insemination procedure.
Semen quality is a determining factor in the final outcome. Depending on the circumstances, if at the third or fourth attempt a pregnancy is not achieved, more complex techniques may be considered, such as In Vitro Fertilisation (IVF).
