RESUMO
Adenomyosis has been associated with adverse fertility and pregnancy outcomes, and its impact on the outcomes of in vitro fertilization (IVF) has received much attention. It is controversial whether the freeze-all strategy is better than fresh embryo transfer (ET) in women with adenomyosis. Women with adenomyosis were enrolled in this retrospective study from January 2018 to December 2021 and were divided into two groups: freeze-all (n = 98) and fresh ET (n = 91). Data analysis showed that freeze-all ET was associated with a lower rate of premature rupture of membranes (PROM) compared with fresh ET (1.0% vs. 6.6%, p = 0.042; adjusted OR 0.17 (0.01-2.50), p = 0.194). Freeze-all ET also had a lower risk of low birth weight compared with fresh ET (1.1% vs. 7.0%, p = 0.049; adjusted OR 0.54 (0.04-7.47), p = 0.642). There was a nonsignificant trend toward a lower miscarriage rate in freeze-all ET (8.9% vs. 11.6%; p = 0.549). The live birth rate was comparable in the two groups (19.1% vs. 27.1%; p = 0.212). The freeze-all ET strategy does not improve pregnancy outcomes for all patients with adenomyosis and may be more appropriate for certain patients. Further large-scale prospective studies are needed to confirm this result.
RESUMO
OBJECTIVE: To evaluate the effectiveness of bromocriptine for prevention of ovarian hyperstimulation syndrome (OHSS). METHODS: The retrospective study included women at risk of OHSS who were receiving gonadotropin-releasing hormone antagonist protocols, including 52 women given 2.5 mg bromocriptine by rectal insertion, 52 women given 500 ml intravenous hydroxyethyl starch (HES), and 40 women who received no intervention. Treatments were administered daily for 5 days beginning on the day of oocyte retrieval. Baseline information and data related to OHSS were compared. RESULTS: No significant differences were found among groups in estradiol concentration on the day of trigger or in number of retrieved oocytes. Incidence of mild OHSS was not significantly different among groups, respectively 13.5%, 15.4%, and 17.5% (P > 0.05). The incidence of moderate to severe OHSS was significantly lower in the bromocriptine and HES groups compared with the control group, respectively 7.7%, 5.8%, and 22.5% (P < 0.05). D-dimer levels were significantly lower in the bromocriptine and HES groups compared with the control group on Day 5 after oocyte retrieval (P < 0.05). No differences in liver or renal function were found in the three groups. CONCLUSION: Bromocriptine was apparently as effective as intravenous HES in patients with high risk of OHSS.

BACKGROUND: To evaluate the effects of controlled ovarian hyperstimulation (COH) on ovarian reserve function during in vitro fertilization and embryo transfer (IVF-ET). METHODS: From August 2018 to August 2020, the medical records of patients who received IVF-ET in the Department of Reproductive Medicine, Beijing Gynaecology and Obstetrics Hospital, Capital Medical University were analyzed retrospectively. Among them, 372 patients received 2 cycles of COH, 54 patients received 3 cycles, and 13 patients received 4 cycles. The levels of follicle-stimulating hormone (FSH), the number of antral follicles, levels of anti-Müllerian hormone (AMH), the total amount of gonadotropin (GN), the time of ovulation induction, the number of eggs obtained, the number of available embryos, and the number of high-quality embryos cycles were compared in different treatment. RESULTS: The age of female patients did not significantly affect the levels of AMH or FSH during menstruation, nor the number of antral follicles before ovulation induction (P>0.05). However, with an increase in age, an increase in the number of controlled COH cycles was observed. In patients who underwent 2 COH cycles, the number of high-quality embryos in the second cycle increased significantly compared to the first cycle (P<0.05). However, there were no significant differences in the ovulation induction time, the number of eggs, the GN dosage, and the number of available embryos (P>0.05). In patients with 3 treatment cycles, the GN dose used in the third cycle was significantly lower than that used in the first cycle (P<0.05). There were no significant differences in the ovulation induction time, the number of eggs obtained, and the quality of embryos (P>0.05). In patients with 4 treatment cycles, significant differences were observed in the ovulation induction time between the first and the fourth controlled COH cycle (P<0.05). However, no significant differences were detected in GN dosage, ovulation induction time, the number of eggs obtained, the number of available embryos, and the quality of embryos (P>0.05). CONCLUSIONS: Ovarian reserve function was not significantly affected in patients with up to 4 ovarian stimulation cycles.
