What should I do if my semen volume is too low?
If a man is diagnosed with oligospermia—defined as a sperm concentration of fewer than 15 million sperm per milliliter of semen, according to the World Health Organization (WHO) 6th edition criteria—it’s important to approach the condition systematically. First, confirm the diagnosis with at least two properly collected and analyzed semen analyses, spaced at least seven days apart and ideally after 2–7 days of sexual abstinence. Transient reductions in sperm count can result from recent illness, fever, medication use (e.g., sulfasalazine, anabolic steroids, or certain antihypertensives), recreational drug use, excessive alcohol intake, or significant stress.
A thorough evaluation should include a detailed medical, surgical, and family history; physical examination focusing on testicular volume, consistency, and presence of varicoceles; and targeted laboratory testing—such as serum follicle-stimulating hormone (FSH), luteinizing hormone (LH), testosterone, prolactin, and thyroid-stimulating hormone (TSH). Genetic testing (e.g., karyotype and Y-chromosome microdeletion analysis) may be indicated in cases of severe oligospermia or non-obstructive azoospermia. Scrotal ultrasound can help identify structural abnormalities like varicoceles, testicular microlithiasis, or tumors.
Management depends on the underlying cause. For varicocele-associated oligospermia, surgical or percutaneous embolization may improve semen parameters in select patients, particularly those with palpable varicoceles and progressive decline in sperm quality. Hormonal imbalances—such as hyperprolactinemia or hypogonadotropic hypogonadism—may respond to medical therapy (e.g., dopamine agonists or gonadotropin replacement). Lifestyle modifications are foundational: cessation of tobacco and illicit drug use, moderation of alcohol, maintenance of healthy body weight, avoidance of scrotal hyperthermia (e.g., hot tubs, tight underwear), and optimization of nutrition—including adequate intake of antioxidants (e.g., vitamin C, vitamin E, selenium, zinc) supported by some evidence for modest improvement in sperm concentration and motility.
In cases where conception remains elusive despite intervention, assisted reproductive technologies (ART) such as intrauterine insemination (IUI) or in vitro fertilization (IVF) with intracytoplasmic sperm injection (ICSI) offer effective pathways to biological parenthood. Referral to a board-certified reproductive urologist or fertility specialist is strongly recommended for personalized assessment and coordinated care.
