Factors That Impact Male Fertility


When a couple struggles with infertility, attention often focuses intensely on evaluating the woman first. Yet we know male factor issues play at least a partial causative role around 30-50% of the time. As an experienced reproductive urologist, having cared for thousands of hopeful fathers over my career, I cannot stress enough how essential it is for the male partner to undergo comprehensive fertility testing right from the start, too! In today’s post, I’ll overview what specific medical, genetic, anatomical, chromosomal, hormonal, lifestyle, and environmental influences can impact sperm quantity or quality – plus fertility interventions that may help overcome various male factor challenges.

Medical Conditions & Prior Surgeries

Certain health conditions and prior procedures affecting the reproductive tract, its blood supply, or nerve inputs can impair the sperm production environment within the testes and downstream maturation factors. Testicular cancer, infection, torsion/trauma, undescended testes during development, inguinal hernia repair, and abdominal/pelvic surgeries especially pose concerns for later fertility depending on severity, healing factors, and if both testes remain intact. Removing varicoceles, however, usually improves sperm parameters.

Genetic Abnormalities

Beyond well-known chromosomal disorders like Klinefelter’s or structural microdeletions on genes impacting sperm quality, even more, subtle single nucleotide genetic polymorphisms are now hypothesized to degrade male fertility. Comprehensive genetic testing via advanced techniques sheds profound insights!

Anatomical Defects

Blockages, strictures, missing seminal emission tubules, or vas deferens duct issues can prevent adequate sperm delivery. Hypospadias, cryptorchidism, and regressed testes may correlate, too. Thorough medical workup via imaging tests, lab urinalyses, seminal analyses, urodynamics, and visual structural inspection is critical!

Hormonal Imbalances

The hypothalamic-pituitary-gonadal axis governs proper testosterone, FSH, LH, and other hormones integral to sperm cell development and maturation. Medications, steroids, pituitary disease, being overweight, and certain endocrine disorders frequently disrupt this finely orchestrated balance, significantly hindering fertility.

Chromosomal Issues

The male carriers have a higher risk for X/Y chromosomal irregularities negatively impacting sperm function, given its tendency to gain or lose such chromosomes within prolific stem cell lines. Genetic testing provides clarity.

Lifestyle Factors

Everything from heavy alcohol/smoking to marijuana usage, frequent sauna/hot baths, poor sleep hygiene, too much endurance exercise, wearing tight undergarments, excess stress, and malnutrition reduces sperm parameters long term through direct toxicity, oxidative injury, hormonal disruption, and inflammation.

Environmental Toxins

Occupational/ambient exposures to pesticides, BPA plastics, heavy metals, other endocrine-disrupting chemicals, and high-supplementary ionizing radiation sources correlate to declining sperm quality, according to still emerging but concerning research data.

Fortunately, both low and high-tech fertility treatment options exist to help overcome various diagnoses of male factor infertility from TESE sperm retrievals to optimize any sperm available coupled with advanced IVF techniques for couples with even profoundly low sperm counts or poor function. Newer experimental methods like priming spermatogonial stem cells for restoration show great promise, too! The key is determining the root cause through comprehensive individual/couple fertility assessments, then thoughtfully mapping treatment plans tailored to address contributing issues uncovered for your family’s unique needs.
