Antimüllerian Hormone and Endometrial Thickness in Predicting Xfollicular Maturation in Patients with Polycystic Ovary Syndrome
Overview
Affiliations
Background: Polycystic ovary syndrome is an anovulatory infertility problem that requires the treatment of ovulation induction. Clomiphene citrate is a first-line regimen for ovulation induction. The antimüllerian hormone is produced by granulosa cells of small, growing follicles in the ovary. Folliculogenesis is an essential process for ovarian function. Endometrial thickness is important throughout a female's life, especially concerning medications for ovulation induction.
Objective: This study aimed to determine the role of basal antimüllerian hormone and midcycle endometrial thickness in predicting follicular maturation and pregnancy in patients with polycystic ovary syndrome treated with clomiphene citrate.
Study Design: This was a prospective cohort study that was conducted at El-sir Abualhassan's Fertility Center (September 2020 to August 2021). The study included 197 patients with polycystic ovary syndrome diagnosed using the Rotterdam criteria. The patients were treated with a dosage of 100 mg of clomiphene citrate. Data were collected using a questionnaire that was filled out after informed consent was provided by the patients. The basal antimüllerian hormone level was measured using enzyme immunoassay, and endometrial thickness and follicular size were measured before and after clomiphene citrate treatment using transvaginal ultrasound. The data were analyzed using SPSS (version 23; IBM Corporation, Armonk, NY). Moreover, the correlation was performed using the chi-square test.
Results: Almost two-thirds of the participants have normal antimüllerian hormone levels. Before clomiphene citrate was used as the treatment regimen, 95.40% of the patients had an endometrial thickness of ≤5 mm and a follicular size of 1 to 6 mm. After clomiphene citrate treatment, 74.60% of the patients had an endometrial thickness of 6 to 10 mm, and 46.20% of the patients had a follicular size of 7 to 12 mm. A significant correlation was found between basal antimüllerian hormone, follicular maturation, and pregnancy (=.001). There was a significant association between endometrial thickness after clomiphene citrate treatment and achieving pregnancy (=.001).
Conclusion: Clomiphene citrate is a first-line regimen for patients with polycystic ovary syndrome with normal antimüllerian hormone levels. After clomiphene citrate treatment, there was a correlation between antimüllerian hormone and follicular maturation and pregnancy. Moreover, there was a correlation between midcycle endometrial thickness and pregnancy.
