What is the Fertility Hormones Profile Test?

The Fertility Hormones Profile is a blood test that measures Follicle-Stimulating Hormone (FSH), Luteinising Hormone (LH), oestradiol and prolactin. These hormones play a central role in regulating the menstrual cycle, ovulation, sperm production and overall reproductive health.

FSH and LH are produced by the pituitary gland and control ovarian or testicular function, while oestradiol is the primary form of oestrogen involved in reproductive tissue development. Prolactin influences reproductive hormone regulation and milk production and can affect fertility when elevated.

This profile is commonly used in fertility assessments for both women and men.

Why do I need a Fertility Hormones Profile?

You may need this test if you are experiencing difficulty conceiving, irregular menstrual cycles or symptoms of hormonal imbalance. Hormonal disruptions can interfere with ovulation, sperm production and reproductive timing.

Testing these hormones together provides a clear overview of reproductive hormone signalling and helps guide further investigation or treatment, including fertility planning or endocrine referral.

Symptoms and scenarios where testing is recommended:

• Difficulty conceiving
• Irregular or absent periods
• Suspected ovulation issues
• Early or delayed puberty
• Symptoms of hormonal imbalance
• Reduced libido
• Abnormal lactation (galactorrhoea)
• Fertility assessment or planning

What’s Tested in This Profile?

• Follicle-Stimulating Hormone (FSH)
• Luteinising Hormone (LH)
• Oestradiol
• Prolactin

Step-by-Step: How Testing Works

Choose your preferred testing method

You can attend one of our UK partner clinics or arrange a home or hotel visit with a mobile phlebotomist.

Option 1 – In-Clinic Blood Draw

1. Select your nearest UK clinic and book an appointment.
2. A clinician or phlebotomist collects a venous blood sample.
3. The sample is analysed for fertility hormone levels.
4. Results are delivered securely online.

Option 2 – Home or Hotel Phlebotomy (+£60)

1. Book a UK-wide home or hotel visit at a convenient time.
2. A trained phlebotomist collects your blood sample on-site.
3. The sample is transported to the laboratory.
4. Results are uploaded digitally without the need to travel.

Your Results Explained

Low Levels

Low FSH, LH or oestradiol may indicate hypothalamic or pituitary dysfunction, while low prolactin is usually not clinically significant.
Low oestradiol may be associated with ovarian insufficiency or hypothalamic causes.
UK reference ranges vary by cycle phase and sex.

Normal Levels

Normal results suggest balanced reproductive hormone signalling.
This supports healthy ovulation, menstrual regularity or sperm production depending on clinical context.

High Levels

High FSH and LH may indicate reduced ovarian reserve or testicular dysfunction.
Elevated prolactin can suppress ovulation and affect fertility and may require further investigation.
