This trial is active, not recruiting.

Condition other complications associated with artificial fertilization
Treatments testosterone and fshr-lhr, testosterone and fshr alone
Sponsor Hospital Clinic of Barcelona
Start date January 2011
End date June 2011
Trial size 104 participants
Trial identifier NCT01291212, FIV-01


The investigators have previously demonstrated the utility of transdermal testosterone in in vitro fertilization (IVF) low responder patients. Now, the investigators want to evaluate the efficacy of luteinizing hormone (LH) activity added to recombinant follicular stimulating hormone (FSHr) during ovarian stimulation in these patients.

Additional Information

Official title Efficacy of LH Activity in Low Responder Patients With Transdermal Testosterone: a Randomised Controlled Study.
Description 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.
