Part 2/9:
Low or Zero Sperm Production: The testes, which produce sperm, may be damaged due to injury, infection, cancer treatments, or genetic conditions like cystic fibrosis, leading to insufficient sperm.
Blockages in the Reproductive Tract: These “plumbing issues” prevent sperm from traveling through the inflamed or fibrotic tubes to reach the semen and, ultimately, the partner's egg.
Poor Function or Abnormal Sperm: Even if sperm count and motility are normal, some sperm may be unable to fertilize the egg due to abnormal morphology or function, often influenced by environmental toxins, radiation, or lifestyle factors.
