“…The ability of this regimen to prevent the LH surge is well established (7,8). The patients in the present study ovulated 5 to 15 days after the cessation of estrogen therapy (mean 9.8 Ϯ 2.7 days, median 10 days), in agreement with the findings of de Ziegler et al (9) that exogenous estrogen may inhibit follicular recruitment and growth for up to 2 weeks after the onset of the last menstrual period.…”

“…It has been demonstrated that short (6 days) (20) or prolonged (5 weeks) (21,22) exposure of the endometrium to estrogen allows normal endometrial maturation and permits great flexibility for endometrial synchronization. On the other hand, lower serum estradiol concentrations and higher early abortion rates were observed in patients after short estrogen exposure (5-10 days) (23).…”

Purpose: Determine if estrogen used since the beginning of the menstrual flow could improve endometrial tissue compared to standard endometrial preparation for in vitro maturation cycles.Methods: Twenty polycystic ovary syndrome women were submitted to two estrogen therapy schedules: standard schedule; estrogen began on the day of planned egg retrieval (dosage was based on endometrial thickness); and long schedule; estrogen began on the first day of menstruation. No oocyte retrieval or embryo transfer was performed. Three-dimensional ultrasound was performed on the day of planned egg retrieval and one week later for endometrial evaluation.Results: A higher endometrial thickness and volume was found in long schedule on both evaluations. The number of patients that have used 10 mg/day of estradiol was significant higher in the standard schedule (65% × 0%). No other significant difference was found.Conclusions: The early use of estrogen improves endometrial tissue and requires lower daily dosage.
