Ovarian hyperstimulation syndrome The ovaries can swell, leak excess fluid into the body, and produce too many follicles, the small fluid sacs in which an egg develops. Unexplained infertility in women or men may be managed with another year of unprotected intercourse, or may proceed to assisted reproductive technologies, such as intrauterine insemination or in vitro fertilization.
