FSH plays a key role in reproductive health, influencing fertility, menstrual cycles, and hormone regulation. In women, it helps control ovarian function and egg production, while in men, it supports sperm production. This test is useful for assessing fertility, menstrual irregularities, menopause status, or hormone imbalances.
If you have periods
Tests with LH, FSH, or oestradiol
If you're taking your test to learn more about your fertility, take your test between days 2 and 5 of your menstrual cycle, or ideally day 3. Otherwise, for a general health check or if you're postmenopausal, you can take your test at any time.
In either case, it's important to log the date of your last period, and any other information regarding your periods or menopause status, in your MyMedichecks account right after taking your sample.
If you don't let us know the date of your last period, we'll interpret your result as though you took your test on day 3.
