Follicle-stimulating hormone receptor polymorphism (Thr307Ala) is associated with variable ovarian response and ovarian hyperstimulation syndrome in Indian women.
We sequenced the region of the FSHr gene encompassing the A307T and S680N polymorphisms of exon 10 of FSHr in 37 Caucasian females who developed OHSS after an IVF cycle in our fertility clinic, 130 Caucasian female patients who were treated by i.v.f. but never developed OHSS, and 99 Caucasian female controls.
