FSH & LH Test

Measures the two pituitary hormones central to fertility, ovulation and reproductive health in women and men.

FSH and LH are the two pituitary hormones at the centre of fertility and reproductive health, and measuring them is a key step in assessing ovulation and hormonal balance.

About the FSH & LH Test

This test measures Follicle-Stimulating Hormone (FSH) and Luteinising Hormone (LH), which regulate the ovaries in women and the testes in men. In women, these hormones guide the menstrual cycle and ovulation and help assess fertility and menopausal status; in men, they help investigate fertility and testosterone production. They are a core part of any reproductive hormone assessment.

Preparation and turnaround

A venous blood sample is taken; in women, the timing within the menstrual cycle is often important, and our team will advise when you book. Fasting is not usually required. Results are typically available within one to two working days and are best interpreted by a doctor.

Frequently asked questions

Does the timing in my cycle matter?

Yes. For women, FSH and LH are often measured on specific days of the menstrual cycle. We will advise the best timing when you book.

What can these hormones reveal?

They help assess fertility, ovulation and menopausal status in women, and fertility and testosterone regulation in men.

Is fasting required?

No fasting is generally needed for FSH and LH testing.

Some tests require fasting. We'll confirm any preparation (such as fasting for 8–10 hours) when we confirm your appointment. When in doubt, ask us at booking.
