A trial of a new regimen with clomiphene citrate administration to reduce the antiestrogenic effects on reproductive end organs.
OBJECTIVE
To determine the endocrinological and clinical outcomes of a 3-day clomiphene citrate (CC) regimen and compare it with the classical 5-day clomiphene citrate regimen.


METHODS
59 patients, diagnosed with Class II ovulatory deficiency according to the criteria defined by WHO, were randomized into two groups. Patients in Group I received 50mg per day of CC for 3 days starting on the first day of the cycle during 72 cycles. Group II received 50mg per day of CC for 5 days starting on the fifth day during 64 cycles.


RESULTS
The ovulation rate was significantly higher in Group II (78.11%) compared to Group I (63.88%) (P < 0.05). However, the implantation rate was higher in Group I than Group II.


CONCLUSIONS
We observed that starting CC on the first day of the cycle for 3 days would lead to higher implantation rates compared to the classical 5-day CC therapy.
