Consequently, the high predictive value of day 4 estradiol levels emphasizes the importance of the early follicular phase in ovulation induction and its critical influence on both oocyte development and pregnancy outcome. Estradiol levels obtained on the fourth day of gonadotropin therapy offer an ...

E 2 was measured in the serum on the day of hCG (day 0), on the day of oocyte retrieval (day 2), and at midluteal phase (days 6–8), as well as in the follicular fluid (FF) using a solid-phase direct RIA. Mean serum E 2 was significantly higher at all three sampling times...
The follicular phase FSH and midcycle surge of gonadotropins are inhibited. In addition, combination hormonal contraceptives produce alterations in the genital tract, including changes in the cervical mucus, rendering it unfavorable for sperm penetration even if ovulation occurs. Changes in the ...
Follicular-phase serum estradiol showed a rising curve in both groups; day-by-day comparison (days 10 to 3 before the luteinizing hormone peak) showed consistently higher levels in the diabetic group (mean, 108 pg/ml versus 95 pg/ml; P < 0.001). The follicular-phase serum estradiol to ...
The follicular phase FSH and midcycle surge of gonadotropins are inhibited. In addition, oral contraceptives produce alterations in the genital tract, including changes in the cervical mucus, rendering it unfavorable for sperm penetration even if ovulation occurs. Changes in the endometrium may also ...
Medroxyprogesterone acetate (Provera) was administered orally during 2-4 days to women undergoing endometrial curettage during the follicular phase of the menstrual cycle. Estradiol (E2) receptor levels were estimated from the amounts of 2H-E2 tightly bound in nuclei after incubation of endometrial tis...
To detect the follicular phase.Objective: To assess E2 in early follicular phase as a predictor of pregnancy rate among females undergoing in vitro fertilization (IVF) in the Baghdad patient.Method: The study population consisted of women undergoing in vitro fertilization and aged between 20-45 ...
