Association of Immunoreactive-Inhibin Levels with Luteal Function
View through CrossRef
To evaluate immunoreactive (IR) inhibin as a marker of corpus luteum function, 134 women with natural ovulatory cycles were studied. Serum IR-inhibin levels during the luteal phase were significantly lower in women with low progesterone (P<sub>4</sub>) levels ( < 10 ng/ml). Endometrial dating correlated more with serum P<sub>4</sub> than IR-inhibin levels. All 14 conceiving cycles showed serum P<sub>4</sub> levels 5=10 ng/ml and IR-inhibin levels ≧3.67 IU/ml during the midluteal phase. Furthermore, IR-inhibin levels in the early follicular phase seemed to be associated with lowered P<sub>4</sub> levels in the ensuing luteal phase. These results suggest that IR inhibin may be closely related to corpus luteum function.

Title: Association of Immunoreactive-Inhibin Levels with Luteal Function
Description:
To evaluate immunoreactive (IR) inhibin as a marker of corpus luteum function, 134 women with natural ovulatory cycles were studied.
Serum IR-inhibin levels during the luteal phase were significantly lower in women with low progesterone (P<sub>4</sub>) levels ( < 10 ng/ml).
Endometrial dating correlated more with serum P<sub>4</sub> than IR-inhibin levels.
All 14 conceiving cycles showed serum P<sub>4</sub> levels 5=10 ng/ml and IR-inhibin levels ≧3.
67 IU/ml during the midluteal phase.
Furthermore, IR-inhibin levels in the early follicular phase seemed to be associated with lowered P<sub>4</sub> levels in the ensuing luteal phase.
These results suggest that IR inhibin may be closely related to corpus luteum function.
