Percutaneous Epididymis Sperm Aspiration (PESA) in Delhi, India

The single winning sperm was the one that entered the egg first. The modern infertility treatments intracytoplasmic sperm injection (ICSI) and in vitro fertilization (IVF) now make it possible to extract a single sperm and use it to directly fertilize an egg. The latest surgical sperm retrieval techniques combined with ICSI and IVF also mean that infertility can be overcome even in men who produce hardly any sperm. A low sperm count is a common cause of male infertility but if a man produces even the tiniest number of sperm in his semen, these can be collected fairly easily. Men who ejaculate no sperm, because of blocked tubes in their testes, or because of a genetic condition that prevents their sperm being released, require some form of surgical sperm retrieval to enable intracytoplasmic sperm injection to take place.

The success rate will depend very much on the IVF live birth success rates of the particular in vitro fertilization laboratory. IVF success rates are also dependent on the age of the female partner - even in these "male factor" cases after vasectomies. We would generally expect the success rates to be about the same as (or somewhat higher) the rates for other couples with a female partner of the same age going through IVF.
