Male infertility is typically diagnosed through semen analysis and physical examination. While there isn't a single blood test to diagnose male infertility itself, blood testing plays a fundamental role in identifying underlying factors that may contribute to fertility issues, such as hormonal imbalances and nutritional deficiencies.
Recommended Test

Selenium is an essential trace element that plays a crucial role in sperm production and male reproductive health. Low selenium levels can negatively impact sperm quality and contribute to male infertility. This test helps identify selenium deficiency, which may be corrected through dietary changes or supplementation to support optimal fertility.
