Abstract

  • 1.

    1. Identification of endogeneous steroids in Mytilus edulis (progesterone, androstenedione, testosterone, 5α-dihydrotestosterone, estradiol-17β, estrone, androsterone and androstanediol) in male and female specimens, was carried out by gas chromatography-mass spectrometry.

    2. The levels of progesterone, androstenidione, testosterone, estradiol-17β and estrone were estimated by means of RIA in specimens collected at two different months of the year.

  • 3.

    3. The levels of progesterone and androstenedione are higher than those of the other steroids, and show a different pattern between both samples.

  • 4.

    4. These differences allow us to suggest a possible function of these steroids in the reproduction of Mytilus edulis.
