Low sperm count or poor sperm quality is among the most frequent causes identified during male infertility evaluation. Other contributing factors include hormonal imbalances, varicocele, infections, lifestyle habits and, in some cases, structural or genetic conditions affecting sperm production.
- Low sperm count or reduced sperm motility
- Varicocele, an enlargement of veins within the scrotum
- Hormonal imbalances affecting testosterone and related hormones
- Past infections or inflammation affecting reproductive organs
- Lifestyle factors including smoking, alcohol use and chronic stress
- Structural blockages preventing normal sperm transport
