OBJECTIVES We examined the prevalence of Early Intervention (EI) enrollment in Massachusetts comparing singleton children conceived via assisted reproductive technology (ART), children born to mothers with indicators of subfertility but no ART (Subfertile), and children born to mothers who had no indicators of subfertility and conceived naturally (Fertile). We assessed the natural direct effect...

It is known that the follicular selection and final stages of follicular maturation are equal if not more dependent on low circulating levels of LH.In addition to stimulating production of thecal androgens as substrate for estrogen synthesis, LH stimulates granulose cell via LH receptors induced by FSH and estrogen in larger but not smaller follicles. The data from numerous assisted reproductio...
