    Which are the hormones that the placenta secretes?
    I have contradicting facts from the web, from my books and from my teachers
    I know for certain HCG, HPL and relaxin are secreted, other than that?

    Hey, that link says that HCG is secreted by the fertilised egg and not the placenta! Huh?

    The wikipedia article says the same thing. Its a good question to ask your teacher. It seems the hormones are used to communicate so the egg gives off the HCg and the placenta recognizes it and starts to give off other hormones.

    What our teacher explained was that HCG is similar to LH in structure and similar to Progesterone in function, it actually stimulates the corpus Luteum to secrete progesterone
    We were told that progesterone is not secreted directly from the placenta
    I think thats wrong

    Maybe that's true only in the early parts of pregnancy
    What do they mean by later stages of pregnancy ?

    That wasn't my question
    I meant "later part of the pregnancy" because later is relative, so in this context when exactly is that?
