This cross-sectional study aims to compare the effectiveness of oral contraceptives, oral progesterone (didrogesterone), and inositol in regulating menstrual cycles among women diagnosed with polycystic ovary syndrome (PCOS).
PCOS is a common endocrine disorder affecting reproductive-aged women and is associated with menstrual irregularities, hyperandrogenism, and polycystic ovarian morphology. While oral contraceptives are the mainstay of treatment, their use may be contraindicated in patients with cardiovascular risk factors, liver dysfunction, or in those who desire pregnancy.
This study investigates whether oral progesterone and myo-inositol can serve as effective and safer alternatives for menstrual regulation and improvement of ovarian morphology and hyperandrogenic symptoms.
A total of 150 women aged 15-40 years with a diagnosis of PCOS will be enrolled and divided into three equal groups:
Group 1: Oral contraceptive users
Group 2: Oral progesterone users
Group 3: Inositol users The study will assess changes in menstrual regularity, ovarian morphology (via ultrasound), and clinical features such as hirsutism and acne before and after treatment.

A retrospective comparison of live birth rate in freeze-all cycles between progestin-primed ovarian stimulation with dydrogesterone and GnRH antagonist protocols

Article

Author: Pham, Toan Duong ; Ho, Nguyen-Tuong ; Le, Ho Long ; Vuong, Lan Ngoc ; Le, Tien Khac ; Ho, Tuong Manh ; Le, Xuyen Thi-Ha

RESEARCH QUESTION:

Does progestin-primed ovarian stimulation (PPOS) using dydrogesterone yield a live birth rate comparable with the gonadotrophin-releasing hormone (GnRH) antagonist protocol in in-vitro fertilization (IVF) freeze-all cycles?

DESIGN:

This retrospective cohort study, conducted at a tertiary hospital from June 2022 to January 2024, included 1045 women aged 18-40 years undergoing IVF/intracytoplasmic sperm injection with freeze-all indications. Participants were assigned to receive PPOS-dydrogesterone (n = 482) or GnRH antagonist (n = 563), followed by frozen embryo transfer (FET). The primary outcome was the live birth rate after the first FET cycle.

RESULTS:

The live birth rate after the first FET cycle were comparable between the PPOS-dydrogesterone (35.1 %) and GnRH antagonist (40.3 %) groups (p = 0.092), showing no significant difference. The PPOS-dydrogesterone group experienced a longer stimulation period [mean ± standard deviation (SD) 8.4 ± 2.0 vs 8.0 ± 2.0 days; p = 0.002] and a higher gonadotrophin dosage (mean ± SD 2622.2 ± 818.8 vs 2413.4 ± 663.4 IU; p < 0.001) than the GnRH antagonist group, but produced more blastocysts (mean ± SD 6.3 ± 3.9 vs 5.6 ± 3.5; p = 0.013). Multivariate analysis showed that age [adjusted odds ratio (aOR) 0.96, 95 % confidence interval (CI) 0.93-0.99; p = 0.006] and anti-Müllerian hormone concentration (aOR 1.05, 95 % CI 1.01-1.10; p = 0.011) were key predictors of live birth, overshadowing protocol effects (aOR 1.27, 95 % CI 0.98-1.67; p = 0.076).

CONCLUSION:

The PPOS-dydrogesterone protocol has a similar live birth rate to the GnRH antagonist protocol in IVF freeze-all cycles, with added benefits in blastocyst yield despite higher stimulation demands. Patient factors, rather than protocol choice, primarily drive outcomes, positioning the PPOS-dydrogesterone protocol as an effective alternative to the GnRH antagonist protocol.
