Follicular phase of the menstrual cycle and action of FSH The decrease in FSH levels means that only on...

(also known scientifically as estradiol) which stimulates growth and thickening of the uterine lining. The follicular phase concludes at the start of ovulation – the process of releasing a mature egg from the dominant follicle. The length of the follicular phase is variable between individuals, ...
