exp date isn't null, but text field is


OHSS is self-limiting and usually resolves spontaneously within several days. However, it may persist for longer particularly in those women receiving assisted conception treatment.

Mild OHSS is common – it occurs in up to 33% of IVF treatment cycles. Moderate to severe OHSS is rare (occurs in 3 to 8% of IVF treatment cycles) but is life threatening. The clinical course is, however, a continuum of scope and severity.
