Male infertility is broadly classified into obstructive and non-obstructive categories. Obstructive infertility results from physical blockage preventing sperm from entering the ejaculate, while non-obstructive infertility reflects impaired sperm production within the testes.
Obstructive causes may include congenital bilateral absence of the vas deferens, infections, trauma, or prior vasectomy. Hormone levels in these patients are typically normal, and testicular size is preserved.
Non-obstructive infertility may result from genetic abnormalities, varicocele, hormonal imbalance, exposure to toxins, or idiopathic factors. Elevated FSH levels often indicate primary testicular failure.
Diagnosis requires semen analysis, hormonal evaluation, imaging, and occasionally genetic testing. Testicular biopsy may help differentiate between maturation arrest and Sertoli cell-only syndrome.
Treatment varies accordingly. Microsurgical reconstruction may restore patency in obstructive cases, whereas sperm retrieval techniques combined with assisted reproductive technologies offer solutions in non-obstructive cases.
Precise differentiation ensures optimal management and erotic improved reproductive outcomes.
