A state of being less than normally fertile, but not infertile.

More or less definite causes can include oligospermia, polycystic ovary syndrome and other causes of oligomenorrhea, endometriosis, peritubal adhesions, fibroids (especially submucous fibroids) and increased age, especially of the woman. Synonymous with relative infertility. See also: cumulative chance of pregnancy See also: K-selection
