Objective:
To determine the predictive value of basal estradiol, FSH and inhibin B levels, antral follicle count and mean ovarian diameter of ovarian response in controlled ovarian hyperstimulation (COH), in outcome with normal FSH concentration in early follicular phase of menstrual cycle.
Materials And Methods:
Twenty nine patients undergoing IVF treatment. Blood samples were collected and transvaginal ultrasound was performed on early follicular phase of unstimulated cycle. Controlled ovarian hyperstimulation (COH) was performed on the base of long protocol.
Result(S):
Mean women age and basal FSH levels were significantly higher in cancelled cycles than in the control group, whereas basal inhibin B, mean ovarian diameter and antral follicle count was significantly higher in the latter. Mean basal E2 concentration was similar in both groups.
Conclusion(S):
In women with normal basal FSH level the determination of E2 has no prognostic value of poor response outcome. However, inhibin B, antral follicles count and mean ovarian diameter tests when applied separately are with good prognostic values.
