弱精子症 中国就医指南

Asthenozoospermia is a male infertility condition characterized by reduced sperm motility—specifically, when less than 32% of sperm exhibit progressive forward movement or less than 40% show any motility (per WHO 6th edition criteria). It is one of the most common semen abnormalities encountered in reproductive medicine, often occurring in isolation or alongside oligozoospermia (low sperm count) or teratozoospermia (abnormal morphology), collectively termed OAT syndrome. Pathogenically, asthenozoospermia arises from multifactorial disruptions affecting sperm energy metabolism, structural integrity of the flagellum, oxidative stress balance, and epigenetic regulation. Key mechanisms include mitochondrial dysfunction impairing ATP production; defects in axonemal ultrastructure (e.g., dynein arm deficiencies); excessive reactive oxygen species (ROS) damaging sperm membranes and DNA; varicocele-induced testicular hyperthermia and hypoxia; hormonal imbalances (e.g., low testosterone, elevated prolactin or FSH); chronic genitourinary infections (e.g., prostatitis, epididymitis); and environmental exposures such as smoking, alcohol, obesity, prolonged sedentary behavior, and endocrine-disrupting chemicals (e.g., phthalates, BPA). Epidemiologically, asthenozoospermia affects approximately 15–25% of infertile men globally, with prevalence rising in parallel with lifestyle-related risk factors—studies in urban Chinese populations report incidence rates of 18–22% among men seeking fertility evaluation. Risk factors extend beyond modifiable behaviors to include genetic causes (e.g., DNAH1, CFTR, AURKC mutations), prior chemotherapy/radiation, undescended testes, and metabolic syndrome. Importantly, asthenozoospermia is asymptomatic—men typically present only through couple infertility workup—and carries no direct physical morbidity. However, its psychosocial impact is profound: recurrent diagnostic uncertainty, treatment fatigue, stigma around male infertility, diminished sexual self-esteem, and marital strain significantly reduce quality of life. Patients frequently report anxiety, depression, and avoidance of social situations involving children or family planning discussions. Early diagnosis via standardized semen analysis (with strict temperature control and CASA—Computer-Aided Sperm Analysis) and targeted workup (hormonal profiling, scrotal ultrasound, ROS testing, genetic screening where indicated) enables personalized intervention. Without timely management, spontaneous conception rates remain low (<5% per cycle in severe cases), making evidence-based, multidisciplinary care essential for optimizing natural fertility potential or guiding assisted reproductive technologies (ART) such as IUI or IVF/ICSI.
