Semen quality

Semen quality is a clinical measure of a male's reproductive potential, determined by the concentration, motility, and morphology of spermatozoa, as well as the volume and chemical composition of the seminal plasma (WHO Laboratory Manual, 2021). It is not a discrete molecular target like a protein or enzyme; instead, it is a complex physiological phenotype and a primary diagnostic endpoint for male infertility (StatPearls, 2023). Semen quality is influenced by the integrity of the spermatogenic cycle within the testes and the regulatory signals of the hypothalamic-pituitary-gonadal (HPG) axis (PubMed, 2022). Drugs intended to improve semen quality typically aim to restore hormonal balance—such as Selective Estrogen Receptor Modulators (SERMs) or gonadotropins—or protect developing sperm from oxidative stress through antioxidant supplementation (NIH, 2023). Because it represents a multifactorial biological state rather than a single druggable molecule, 'Semen quality' is categorized as a physiological parameter or clinical outcome.

Pharmacological interventions do not target semen quality directly as a receptor but rather modulate the hypothalamic-pituitary-gonadal (HPG) axis to enhance endogenous production of testosterone and gonadotropins, or utilize antioxidants to reduce oxidative stress-induced damage during spermatogenesis.
