FOLLICULAR-GROWTH AND KINETICS IN THE INDIAN GERBIL (TATERA-INDICA) OVARY DURING ESTROUS-CYCLE

The growth of the follicle and oocyte in the Indian gerbil (Tatera ind ica) was a continuous process. The relationship between follicle and o ocyte or its nucleus was log linear, represented by the equation log Y = a + b logX. A linear relationship (Y = a + bX) existed between the oocyte and its nucleus. The number of stages I and II follicles varied significantly during the oestrous cycle. Maximum percentage of stage I follicles was observed during oestrus and metoestrus, while stage II follicles were abundant during dioestrus, metoestrus and pro-oestrus. These follicles were significantly more in number than other types of the follicles. The occurrence of comparatively larger follicles durin g pro-oestrus and the presence of newly formed corpora lutea at oestru s, indicated ovulation in the early oestrus.
