    Abstract:
    Marked variations in the 3beta-hydroxysterol content of hamster spermatozoa were observed as they progress through the epididymis. Cholesterol is the major sterol of caputal spermatozoa while the concentration of precursors of cholesterol was higher than that of cholesterol in caudal spermatozoa. One of these precursors has been identified as desmosterol. A second sterol has now been identified as 5alpha-cholestra-7,24-dien-3beta-ol by GLC-MS and by NMR. Its concentration is approximately 3-fold higher than that of cholesterol. This 3beta-hydroxysterol is also found in epididymal tissue.
