How can pregnancy be achieved with severe oligospermia?

By Miguel Angel Checa Vizcaino M.D., Ph.D. (gynecologist).
Last Update: 10/21/2022

Severe oligospermia is a very significant decrease in the number of sperm that makes spontaneous gestation impossible, as well as the fertilization of eggs in the laboratory using conventional in vitro fertilization (IVF) techniques.

In order to perform in vitro fertilization, at least 50,000-100,000 spermatozoa are necessary. When the number of spermatozoa is lower than this value, it is very difficult for a natural fertilization of the eggs to take place.

Therefore, in cases of severe oligospermia with a sperm count below 100,000, IVF with ICSI (Intracytoplasmic Cytoplasmic Sperm Injection) is performed.
