[Luteal and follicular phase inhibin A and B in regularly cycling women].

OBJECTIVE

To investigate the level of inhibin A nad B in luteal and follicular phase in women of reproductive age.

PATIENTS

Seventy women 39-52 years of age with regular menstrual cycle.

INTERVENTIONS

Blood samples obtained on days 3-8 and on days 22-25 of menstrual cycle were assayed for FSH, estradiol, inhibin A, inhibin B.

RESULTS

Luteal and follicular phase inhibin B was correlated inversely with age. Luteal phase inhibin A was correlated inversely with follicular phase FSH.

CONCLUSION

Main form of inhibin in follicular phase of the cycle is inhibin B and in luteal phase inhibin A. Inhibin B can be potential marker of ovarian aging.
