Ovarian hyperstimulation syndrome

Ovarian hyperstimulation syndrome, abbreviated OHSS, is a medical condition that can occur in some women who take fertility medication meant to stimulate egg growth, and it also appears in other women in sporadic cases. The source lead describes most cases as mild, while noting that the condition is rarely severe enough to cause serious illness and, in the worst cases, death. The lead does not go further into mechanisms, staging or management, so this entry records only what that summary supports: the link to fertility treatment, the occasional spontaneous case, and the wide range from mild to life-threatening. This entry is a record of the condition, not medical advice.
