What are the ICSI success rates with azoospermia?

By Zaira Salvador B.Sc., M.Sc. (embryologist).
Last Update: 10/07/2022

With a severe male factor such as azoospermia, it will be necessary to perform a testicular biopsy to obtain spermatozoa.

The success of sperm microinjection depends on the embryologist's ability to select sperm that are alive in the biopsy and, if possible, with motility and good morphology. If sperm with these characteristics are found, the success rates are similar to those of a cycle with normal sperm recovery. According to SEF statistics for 2020, the probability of delivery by embryo transfer is 25.3%.
