Circulating Concentrations of Estradiol: DISCUSSION(5)

A possible explanation of the continuous increase in the number of follicles between Days 0 and 9 after follicular aspiration was the effect that aspiration had on the number of follicles < 5 mm. Removal of follicles a 4 mm in diameter resulted in a lesser number of follicles < 5 mm on Day 1 after follicular aspiration as a result of ablating some follicles < 5 mm and removing larger follicles, which would have eventually decreased in diameter and entered the group of follicles < 5 mm in diameter as they underwent atresia. ventolin 100 mcg

The number of follicles < 5 mm increased between 8 and 5 mo prepuberty and decreased between 5 and 1 mo prepuberty. The most likely explanation for the increase in the number of follicles < 5 mm between 8 and 5 mo prepuberty was the increase in the concentration of FSH as females progressed from 8 to 5 mo prepuberty. Because an increase in the concentration of FSH precedes the emergence of waves of ovarian follicular development and is necessary for the initiation of new waves [20], it is possible that the increase in the concentration of FSH between 8 and 1 mo prepuberty resulted in an increase in the recruitment of follicles < 5 mm and more rapid development of follicles < 5 mm to follicles a 5 mm. The increase in follicles a 5 mm as puberty approached may have occurred because a larger number of follicles < 5 mm developed more rapidly to a 5 mm because of the greater concentration of FSH, thus decreasing the number of follicles < 5 mm.
