Subsequent histological evaluation showed that both non-atretic and severely atretic follicles could be correctly identified with over 95% accuracy.<\/jats:p>\n                  <jats:p>The concentrations of steroids were measured in both follicular tissue and fluid. The total steroid content of large (3\u00b71\u20136\u00b70 mm diameter) non-atretic follicles in vivo (115 pmol\/follicle) exceeded that of large atretic follicles (54 pmol) and also that of small (2\u00b70\u20133\u00b70 mm diameter) non-atretic and atretic follicles (6 pmol). Oestrogen accounted for 80%, testosterone 13% and progesterone 7% of the total steroid content in large non-atretic follicles, whereas testosterone accounted for 75% of the steroid content in the other three categories of follicles. A similar pattern is observed when the concentrations of steroids are expressed on the basis of follicular weight.<\/jats:p>\n                  <jats:p>Total oestrogen secretion, as measured by the output of steroid into the culture medium in 24 h, was 937 pmol for large non-atretic, 31 pmol for large atretic, 65 pmol for small nonatretic and 4 pmol for small atretic follicles. In terms of steroid production (pmol\/mg tissue), the four follicular categories were equally efficient. However, the type of steroid produced depended on the category of follicle and corresponded to its steroid content.<\/jats:p>","DOI":"10.1677\/joe.0.0770309","type":"journal-article","created":{"date-parts":[[2008,12,11]],"date-time":"2008-12-11T17:22:29Z","timestamp":1229016149000},"page":"309-318","update-policy":"https:\/\/doi.org\/10.1530\/crossmarkpolicy-5","source":"Crossref","is-referenced-by-count":76,"title":["MACROSCOPIC IDENTIFICATION AND STEROIDOGENIC FUNCTION OF ATRETIC FOLLICLES IN SHEEP"],"prefix":"10.1530","volume":"77","author":[{"given":"R.
