Conclusion
PCOS
In conclusion, the current clinical trial demonstrated that letrozole 2.5mg/FSH was preferable to letrozole 5 mg/FSH for inducing ovulation and promoting pregnancy in infertile women with PCOS. Therefore, letrozole 2.5 mg/FSH is recommended as a superior protocol for ovulation induction. Consequently, in clinical practice, the starting dose of letrozole for ovulation induction is suggested to be 2.5 mg. If this dosage proves ineffective, alternative therapeutic regimens should be considered rather than increasing the dose of letrozole since it does not enhance the patient’s cycle pregnancy rate.
