Effects of Cabergoline administration on uterine perfusion in women with polycystic ovary syndrome

Effect of Aslagh Capsule, a Traditional Compound Herbal Product on Oligomenorrhea in Patients with Polycystic Ovary Syndrome: A Three-Arm, Open-label, Randomized, Controlled Trial

Background:

Oligomenorrhea is a common complaint in patients with polycystic ovary syndrome (PCOS). There are some useful medicinal recommendations such as Aslagh product (include fennel fruits, carrot seeds, chaste tree fruits) in Iranian traditional medicine for the treatment of oligomenorrhea in PCOS. Hence, the present investigation was designed to compare Aslagh capsule with metformin on the oligomenorrhea.

Materials and Methods:

One hundred fifty women aged between 18-43 years with oligomenorrhea due to PCOS were randomly divided into Aslagh, metformin, and Aslagh + metformin groups. The occurrence of menstrual bleeding was considered as the primary outcome. Menstrual cyclicity, duration, and volume of the bleeding were also evaluated.

Results:

Occurrence of menstrual bleeding was 87.2% in all patients, with no significant difference between the three groups (P> 0.05). Menstrual cyclicity significantly improved from baseline in Aslagh and Aslagh + metformin groups (P=0.02). Duration of menstrual bleeding was significantly higher in Aslagh group in the first and the second menstrual bleeding cycle compared to the other two groups (P<0.05). No significant change was observed in the volume of the bleeding after the intervention in any of the three groups. The occurrence of menstrual bleeding in Aslagh group was significantly (P=0.03) higher than the other two groups in the fourth month (drug-free period).

Conclusion:

Aslagh capsule showed beneficial effects similar to metformin in the treatment of oligomenorrhea in PCOS women and could be suggested for use as an alternative treatment in these patients.

Impact of letrozole versus clomiphene citrate on endometrial receptivity in Iraqi women with polycystic ovarian syndrome

WHAT IS KNOWN AND OBJECTIVES

Letrozole is widely known for its use as an ovulation inductor. This study aims to investigate the effects of letrozole and clomiphene citrate in females with polycystic ovarian syndrome.

METHODS

This is a randomized non-blinded controlled trial study that included 80 infertile females with polycystic ovarian syndrome receiving a standard dose of either clomiphene citrate or letrozole on day 2 of the cycle. An ultrasound was done to examine growth of the follicle, endometrial thickness on days 12-13, and a Doppler study to measure resistance index (RI), pulsatility index and ratio of systolic/diastolic velocity.

RESULTS AND DISCUSSION

The mean levels of dominant follicle and oestradiol were significantly higher in the clomiphene citrate group than in the letrozole group. The letrozole group had a significantly greater endometrial thickness than the clomiphene citrate group. The resistance index and pulsatility index were lower in the letrozole group and in pregnant women than in the clomiphene citrate group and the non-pregnant group.

WHAT IS NEW AND CONCLUSION

The use of letrozole for ovulation induction in polycystic ovarian syndrome patients has a better effect on endometrial receptivity markers when compared to clomiphene citrate.

Efficacy of Combined Cabergoline and Metformin Compared to Metformin Alone on Cycle Regularity in Patients with Polycystic Ovarian Disease with Hyperprolactinemia: A Randomized Clinical Trial

PURPOSE

Polycystic ovarian syndrome (PCOS) is a common reproductive disorder. Increasing serum prolactin in these patients could be detected in both follicular and luteal phase of the normal and stimulated cycles. Hyperprolactinemia affects the hypothalamic-pituitary-ovarian axis causing anovulation and abnormal uterine bleeding. In this study, the efficacy of combined cabergoline and metformin therapy was compared to metformin therapy alone in patients with PCOS on the body mass index, androgen profile and menstrual cycle regulation.

METHODS

Two hundred and fifty patients with polycystic ovarian syndrome (PCOS) with increased serum prolactin were randomly allocated into two groups: group (1) received oral metformin tablet 1000 mg per day and cabergoline 0.5 g tablet weekly for 3 months as a case group, and group (2) received oral metformin tablet 1000 mg per day and a placebo tablet weekly for 3 months as the control group (n = 123). Body mass index (BMI), menstrual cycle regularity, serum testosterone, serum prolactin and dehydroepiandrosterone sulfate (DHEAS) level were compared before and after treatment in both groups.

RESULTS

There was significant decrease in body mass index and improvement of androgenic profile in both groups after treatment. In group (1), there was significant improvement in cycle regularity and significant decrease in serum prolactin level post-treatment.

CONCLUSIONS

The use of cabergoline in addition to metformin had more favorable effect on cycle regularity and prolactin level in patients with polycystic ovarian syndrome with hyperprolactinemia than the use of metformin alone.
