Male infertility is said to be the cause of 50% of infertility cases. Azoospermia is one of the most significant diagnoses known (zero sperm in the semen). The development of technology has made this treatable and given men the opportunity to become biological fathers. Azoospermia is the medical term for an ejaculate that contains no sperm. The most likely causes include hormonal imbalances, obstructions in the reproductive tract, problems with testicular structure and function, or complications with ejaculation.
