Brief Summary:
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.

Condition or disease Intervention/treatment Phase
Other Complications Associated With Artificial Fertilization Drug: Testosterone and FSHr-LHr Drug: testosterone and FSHr alone Not Applicable

Detailed 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.

Arm Intervention/treatment
Active Comparator: Testosterone and FSHr Drug: testosterone and FSHr alone
FSHr alone used in ovarian stimulation in IVF, when testosterone was used to improve the ovarian response

Active Comparator: testosterone and FSHr-LHr Drug: Testosterone and FSHr-LHr
75U of LHr added to FSHr ovarian stimulation in IVF, when testosterone was used to improve the ovarian response




Primary Outcome Measures :
  1. ovarian response [ Time Frame: within 2 weeks after begining ovarian stimulation ]
    number of oocytes obtained per ovarian stimulation cycle


Secondary Outcome Measures :
  1. clinical pregnancy rate [ Time Frame: within 5 weeks (plus or minus 1 week) after embryo transfer ]
    The number of clinical pregnancies expressed per embryo transfer cycles. 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.

  2. Implantation rate [ Time Frame: within 5 weeks (plus/minus 1 week) after embryo transfer ]
    The number of gestational sacs (observed by ultrasound examination) divided by the number of embryos transferred.

  3. Live birth rate [ Time Frame: within 9 months (plus/minus 1 month) after embryo transfer ]
    The number of deliveries that resulted in at least one live born baby expressed per 100 embryo transfer cycles.
