A combination of FSH and LH, or LH alone, is sometimes used by fertility specialists to stimulate the ovaries to produce follicles for IVF (in vitro fertilization) or IUI ( intrauterine insemination). These are injectable medications known as Luveris and Menopur.
Women with PCOS sometimes have persistently elevated levels of LH. This may make testing for ovulation using an OPK difficult. If you are having trouble detecting a surge or are getting consistently positive results regardless of the point you are at in your cycle, see your physician or a specialist for assistance.
