Idiopathic Male Infertility

Meaning

Idiopathic male infertility is a clinical diagnosis applied to cases where a man presents with suboptimal semen parameters, such as low sperm count, poor motility, or abnormal morphology, but a thorough clinical and laboratory investigation fails to identify a clear, underlying cause. This condition is essentially a diagnosis of exclusion, representing a significant proportion of male factor infertility cases in reproductive endocrinology clinics. It highlights the current limitations in fully elucidating the complex genetic, epigenetic, and environmental factors that govern spermatogenesis and male reproductive health.
