Follicle Stimulating Hormone S -FSH
Follicle Stimulating Hormone, or FSH, affects the levels of sex hormones, estrogen and testosterone, and the menstrual cycle. The test is taken at the beginning of the natural menstrual cycle (days 3-5 of the cycle). When using hormonal contraceptives (e.g., birth control pills, mini-pills, or contraceptive implants), the result does not reflect the body’s normal hormonal function. It is recommended to conduct the test at least 4 weeks after stopping the use of contraceptives.
