Sterility, or sterility in a biological context, refers to the inability to produce offspring, either through biological or medical means. In humans, sterility can result from various factors affecting fertility, including hormonal imbalances, genetic conditions, anatomical abnormalities, infections, or lifestyle choices. It is important to distinguish sterility from infertility, which refers to the inability to conceive despite regular sexual intercourse without contraception, while sterility implies a complete absence of reproductive capability.

Sterility can be categorized into male and female sterility. Male sterility often arises from issues such as low sperm count (oligospermia), poor sperm motility (asthenozoospermia), or abnormal sperm morphology (teratozoospermia). Conditions like varicocele, infections such as chlamydia or gonorrhea, or genetic disorders like cystic fibrosis can also contribute. Female sterility may stem from blocked fallopian tubes, ovarian disorders such as polycystic ovary syndrome (PCOS), or hormonal imbalances affecting ovulation. Endometriosis and pelvic inflammatory disease (PID) are additional factors that can impair fertility.

Medical interventions can address some causes of sterility. For males, treatments may include medications to improve sperm production, surgical correction of blockages, or assisted reproductive technologies (ART) like in vitro fertilization (IVF) with intracytoplasmic sperm injection (ICSI). For females, options include fertility drugs to stimulate ovulation, surgical repair of fallopian tubes, or ART procedures such as IVF or gamete intrafallopian transfer (GIFT). In cases where sterility is permanent or untreatable, adoption or surrogacy may be considered.

Sterility can also occur in plants and animals, where it may be intentional, such as in the case of sterile hybrids like mules, or unintentional due to environmental factors, genetic mutations, or breeding practices. In agriculture, sterility is sometimes exploited to produce seedless crops or prevent unwanted hybridization. Understanding the causes and potential treatments for sterility is essential for addressing reproductive challenges in both medical and biological contexts.
