Control of Mammalian Oestrus

The mammalian Oestrus Ovulation
Luteal Phase
Bottom Line
Negative feedback from oestrogen to FSH
Positive feedback from oestrogen to LH
Negative feedback from progesterone to LH




We’ve seen that negative and positive feedback loops are fairly straightforward concepts. That’s because we were thinking of just one variable which either gets kept constant or gets increased/decreased continually. What happens when you have a complex interplay between 4 different variables?


The Mammalian Oestrus is Controlled by 4 Hormones: FSH, LH (pituitary gland), Progesterone and Oestrogen (ovaries)
