Hypothesis

The study investigates the interaction of adrenomedullin (ADM) and endothelin-1 (ET-1) in rat ovarian follicles and corpora lutea, and the effects of ADM on progesterone production during pregnancy.

Conclusion

Adrenomedullin may play a crucial role in regulating progesterone production in rat corpora lutea during different stages of pregnancy.

Supporting Evidence

  • ADM levels increased from small antral follicles to large antral follicles and corpora lutea.
  • ADM treatment increased oestradiol production in cultured follicles.
  • The effect of ADM on progesterone production was dependent on the stage of pregnancy.

Takeaway

Adrenomedullin helps control how much progesterone is made in the ovaries during pregnancy, acting differently at various stages.

Methodology

The study used real-time RT-PCR and enzyme immunoassays to measure gene expression and hormone production in rat ovarian tissues.

Participant Demographics

Sprague-Dawley rats, 21-23 days old.
