  1. Individual indices presented by ovarian structure type: preantral follicles, antral follicles, corpora lutea (CL), terminal atretic follicles (TAF), stroma primarily consisting of connective tissue (CT), stroma including potential steroidogenic interstitial glands. Values represented as mean (SEM). Groups with different letters are significantly different (p < 0.05).
