Efficacy of Luteinizing Hormone (LH) Activity in Low Responder Patients With Transdermal Testosterone
Efficacy of LH Activity in Low Responder Patients With Transdermal Testosterone: a Randomised Controlled Study.
研究概览
详细说明
Studies in macaques have indicated that androgens have some synergistic effects with follicular stimulating hormone (FSH) on folliculogenesis. Our previous clinical studies demonstrated the usefulness of pretreatment with transdermal testosterone in low-responder IVF patients.
There is controversy on the usefulness of recombinant luteinizing hormone (LHr) added to FSHr in ovarian stimulation of low responder patients. Thus, our present study has been designed to compare ovarian stimulation with FSHr alone versus LHr added to FSHr when transdermal testosterone pretreatment is used.

Clinical pregnancy: a pregnancy diagnosed by ultrasonographic visualization of one or more gestational sacs or definitive clinical signs of pregnancy.
It includes ectopic pregnancy.
Multiple gestational sacs are counted as one clinical pregnancy.
