Abstract

Introduction: This study aims to determine the effectiveness of simultaneous use of aspirin with clomiphene citrate and letrozole on the success rate of ovulation induction in women with PCOS.

Materials and methods: This study was a double-blind randomized clinical trial. 120 patients with PCOS with complaints of infertility due to lack of ovulation were randomly divided into four groups using clomiphene citrate + placebo, letrozole + placebo, clomiphene citrate + Aspirin, and letrozole + aspirin divided by block randomizes. Follicometry was performed with the help of transvaginal ultrasound on the 14th day of the cycle. In the case of a positive pregnancy, the patients underwent transvaginal ultrasound in the 6th week of pregnancy to observe the gestational sac. Patients were followed up until the 12th week of pregnancy in terms of the abortion rate.

Results: This study showed that there was no significant difference in the number of follicles of 14 to 18 mm, follicles larger than 18 mm, and the thickness of the endometrium of the studied women in the four investigated groups (p>0.05). The pregnancy test results showed that the clomiphene citrate + aspirin group and the letrozole + aspirin group each had the highest pregnancy rate with 13 people (36.1%) having a positive test.

conclusion: Although the addition of aspirin to letrozole or clomiphene citrate does not affect the number of mature follicles and the thickness of the endometrium, it can increase the probability of pregnancy.
