Infections Affecting Fertility

Infections are a significant yet often underrecognized cause of infertility in both men and women. These infections can damage reproductive organs, disrupt normal physiology, and impair gamete function. In women, sexually transmitted infections such as chlamydia and gonorrhea can lead to pelvic inflammatory disease (PID), resulting in scarring of the fallopian tubes, which blocks egg transport and increases the risk of ectopic pregnancy. Chronic infections like tuberculosis, particularly genital tuberculosis in endemic regions, can severely affect the uterus and fallopian tubes, compromising implantation and embryo development.
In men, infections of the reproductive tract, including epididymitis, orchitis, and prostatitis, can impair sperm production, motility, and morphology. Viral infections such as mumps orchitis may lead to testicular atrophy and long-term infertility. Additionally, infections can trigger immune responses that produce anti-sperm antibodies, further reducing fertility potential.

Early diagnosis through screening, laboratory testing, and imaging is essential for effective management. Treatment typically involves targeted antibiotic or antiviral therapy, along with supportive reproductive interventions when needed. Preventive measures, including safe sexual practices, vaccination, and timely medical care, play a critical role in preserving fertility and reducing infection-related reproductive complications.
