Infertility can be traced to either the man or woman, or a combination of both:

Causes of Infertility in Women may Include:
- age (fertility decreases after age 35)
- problems producing eggs (which shows up when she has no period/menstrual cycle, or no regular one)
- having a sexually transmitted infection (STI), like Chlamydia (which can cause blockages in the fallopian tubes)
- problems in the uterus (like fibroids or polyps)
- problems with the fallopian tubes (like missing tubes or blockages)
- endometriosis (excess of tissue that gathers around the reproductive organs)
- hormonal imbalances
- early menopause (before age 40)
