The reproductive process is so intricate that even the most fertile couple has only a one in four chance of conceiving each month.
Conditions that have long been considered as causes of infertility are:
- Failure to ovulate
- Low ovarian reserve
- Low sperm count or low motility
- Tubal obstruction
- Endometriosis
- Underdeveloped uterine lining
- Pelvic adhesions
- Mucus factors
- Uterine fibroids
