Description of intervention(s) / exposure
- Participants will receive a fixed dose of intramuscular/ subcutaneous Human Menopausal Gonadotropin (hMG) 75-150 IU per day starting from day 3 of the menstrual cycle for four days, then participants will receive oral Clomiphene Citrate (CC) till follicle reach 20mm

Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Couples fullfilling the inclusion/exclusion criteria will be recruited from the outpatient clinic. Participants consenting to be included in this trial will be randomised by opening consecutively numbered, sealed, opaque envelopes to determine the treatment allocation.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A computer generated block randomization table will be used randomize patients. The resutls of the randomization scheme will be placed in numbered, dark, sealed envelopes. The randomization process and envelopes containing the treatment allocation will be prepared by a third party not directly involved with the trial.

Summary
Brief summary
Clomiphene citrate (CC) is traditionally given from the 3rd-5th day of the cycle for five days as an ovulation induction drug. The mechanism of CC in stimulating ovulation is unknown but is believed to be related to its anti-oestrogenic properties. As a feed back mechanism, it stimulates the secretion of follicle stimulating hormone (FSH). When serum estradiol reaches a certain level, an leutinizing hormone (LH) surge is released. Of the cycles stimulated by CC and or human menopausal gonadotrophin (hMG), an endogenous LH surge was observed in more than 15% of the patients shortly prior to the HCG injection. In animal experimental studies, CC prevented the positive effects of estradiol required to induce an LH surge.
In a recent pilot study by Branigan & Estes 2006, CC was able to suppress LH surge in human IVF. The hypothesis behind this study is that if CC is given after hMG, the anti-oestrogenic effect will suppress LH surge.
