Undescended testicles
During foetal development, one or both testicles sometimes fail to descend from the abdomen into the sac that normally contains them (scrotum). Chromosome defects Inherited disorders such as Klinefelter’s syndrome — in which a male is born with two X chromosomes and one Y chromosome instead of one X and one Y — cause abnormal development of the male reproductive organs. Other genetic syndromes associated with infertility include cystic fibrosis, Kallmann’s syndrome and Kartagener’s syndrome.
Celiac disease
A digestive disorder caused by sensitivity to gluten, celiac disease can also cause male infertility. Fertility may improve after adopting a gluten-free diet. Certain medications Testosterone replacement therapy, long-term anabolic steroid use, cancer medications (chemotherapy), certain antifungal and antibiotic medications, some ulcer medications and other medications can impair sperm production and decrease male fertility.
