Whats the evidence for hormone injections for women with problems ovulating?
There haven’t been any good studies involving women who have problems ovulating comparing hormone injections to having no treatment, or to clomifene. Most studies have compared different types of hormone injections. These studies included over 2,000 cycles of hormone treatments. Two large reviews (called systematic reviews) have found that older hormone injections (made from urine) and newer ones (made in the laboratory) work about the same to help women ovulate.[1] [2] Between 1 in 10 and 1 in 3 women who have polycystic ovary syndrome (PCOS) get pregnant each cycle using these injections.References Nugent D, Vandekerckhove P, Hughes E, et al.
