Patient's question:
What is male infertility? What are the causes of male infertility?Doctor's answer:
Male infertility is mostly caused by poor semen quality, so a semen analysis is a necessary and thorough examination for every patient. For issues identified in the semen analysis, further investigation may be required to determine their cause. For example, if there are no sperm in the semen, blood hormone testing or a testicular biopsy may be needed to assess the testicular sperm production function. For suspected cases of vas deferens obstruction, a vasography is performed to understand whether there is an obstruction, its extent, and its location. For patients with sexual development abnormalities or a history of recurrent miscarriages, a chromosomal test may be necessary. Infertility conditions can be recurrent, requiring long-term medication maintenance.
