About Day 3 fertility check

What is a day 3 fertility check?

The day 3 fertility check is a measure of reproductive potential in females. It is performed at the beginning of the menstrual cycle on day 3 of a females’ period and measures the levels of three hormones:

●    Follicle-stimulating hormone (FSH) stimulates maturation of eggs ●    Luteinizing hormone (LH) triggers ovulation (release of an egg) ●    Oestradiol (E2) is important for female reproductive development and is critical for the menstrual cycle

Why take the test?

This test is typically used to investigate infertility but may also be used for those planning to have a baby.
