About Founder


Dr. Abuelhija is a scientist in reproductive biology. As a PhD. in the male fertility field for long time has given me the opportunity to think in new directions and change the idea that non-obstructive azoospermia is untreatable.

The old theories about sperm production are changing all the time since we do not fully understand the testis mechanism. Unfortunately, many urologists still believe in the old theories that have been proven false.

Dr. Abuelhija has been involved in male fertility studies since 2004, starting with the effect of cytokines and growth factors on the spermatogenesis in mice and humans,
as well as in vitro cultures of germ cells and the effects of radiation on spermatogenesis recovery in rats.

Dr. Abuelhija is the author and co-author of more than 15 scientific articles, abstracts, and book chapters and specializes in non-obstructive azoospermia and in helping men to increase their chances to restore their fertility.
