Study on Influence of Leutinizing Hormone (LH) on Oocyte Maturity (LH/M2-Oocyte)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT01595334

Brief Summary:
  1. Leutinizing hormone (LH) has been demonstrated to exert variable physiological actions during menstrual cycle at appropriate plasma levels'
  2. In early follicular phase,in the requisite range,LH is known to contribute to maturation of oocyte during transition phase from metaphase-1(M1) to metaphase-2 (M2).
  3. If during this transition, appropriate level of LH can be maintained either through the use of gonadotropin releasing hormone (GnRH) antagonist if found excessive or supplementation with exogenous LH, if found deficient, maturation process can be enhanced.
  4. Further maintenance of suitable combination of recombinant follicle stimulating hormone (rFSH) + rLH can help in realizing higher yield of mature M2 oocytes,with higher probability of establishing clinical pregnancy.

Condition or disease Intervention/treatment Phase
Infertility Drug: Cetrorelix Drug: Luprolide Acetate Not Applicable

Detailed Description:

The study is planned to assess whether maintenance of levels of LH through the use of GnRH antagonist would contribute to obtaining mature M2 oocytes so that maximum number of good quality embryo's with potential to implant is obtained.

The mature oocytes would be subjected to either standard in-vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) depending on the status of the male factor.

The objective would be to obtain good quality embryo's with implantation potential for fresh embryo transfer and/or subsequent frozen thaw embryo transfer.

In both these events, the secondary outcome measures would be establishment of clinical pregnancy by transvaginal ultrasound performed 6 weeks after embryo transfer.

Arm Intervention/treatment
Active Comparator: Study subjects desiring pregnancy

Study subjects to be treated with rFSH, rLH throughout controlled ovarian hyperstimulation (COH) in appropriate dosages,considering age, body mass index (BMI), ovarian reserve, etc. and GnRH antagonist, cetrorelix in 0.25 mg/d when needed till the desired follicular maturity and the minimum required number of follicles are achieved.

INTRVENTIONS - Monitoring at regular intervals by transvaginal ultrasound and hormonal studies.Once pregnancy established by beta-human chorionic gonadotropin (hCG) and ultrasound will be supported by intervention of adequate luteal support by estrogen (E) + progesterone (P) for 12 weeks of gestation.

Drug: Cetrorelix
Cetrorelix 0.25 mg/d would be administered by subcutaneous injection to women when the plasma LH is higher (>4.5 mIU/ml) in the study arm
Other Name: Cetrotide

Control subjects desiring pregnancy

Control subjects selected in randomized way,desiring pregnancy will be treated with gonadotrophins, rFSH and rLH in appropriate dosages considering age, BMI, ovarian reserve, etc. after standard downregulation with GnRH agonist, Leuprolide acetate, 1 mg/d under established 'Long Luteal Suppression Protocol' from the previous cycle.

INTERVENTIONS - Monitoring of response to treatment by hormonal study and sonography evaluation at regular intervals during COH till adequate number of mature follicles of minimum 18 mm mean diameter is achieved, to be followed by hCG trigger and ovum pick-up (OPU) and embryo transfer (ET). Chemical pregnancy by beta-hCG would be confirmed 14 days post-ET. Clinical pregnancy would be confirmed by sonography 6 weeks after ET (visibility of yolk sac and fetal heart-beat). Pregnancy support by E+P for 12 weeks would be provided.

Drug: Luprolide Acetate
Women in the control arm would receive Luprolide acetate 1 mg/day by subcutaneous injection
Other Name: Lupron

Primary Outcome Measures :
  1. Number of mature oocytes immediately after oocyte recovery [ Time Frame: Women would be followed every 2 weeks upto 6 weeks after embryo transfer ]
    Number of mature oocytes would be measured immediately after the oocyte recovery

Secondary Outcome Measures :
  1. Clinical pregnancy [ Time Frame: Women would be followed every 2 weeks upto 6 weeks after embryo transfer ]
    Diagnosed by transvaginal ultrasound.Appearance of yolk sac with fetal heart beat at 6 weeks of gestation.
