Fertility, Hormones & Weight

Endocrine and metabolic assessment that complements fertility care for women, men and couples.

Specialist metabolic medicine

Fertility deserves a complete picture, not a single explanation

Ovulation, sperm health, age, anatomy, thyroid function, PCOS, diabetes, medicines and weight can all contribute. We identify endocrine and metabolic factors we can improve while protecting timely access to specialist fertility investigation.

What's actually happening

At both higher and lower weights, hormonal signalling and ovulation can be affected. In men, metabolic health can also be associated with hormone levels and sperm quality. These are associations, not a verdict on any individual’s chance of conception.

Infertility is often multifactorial. Neither partner should be assumed to be the cause, and weight should not distract from age, anatomy, semen factors or another diagnosis.

Why it's harder than it looks

Weight-management medicines must not be used during pregnancy and need to be stopped before conception in line with current prescribing information. Semaglutide is stopped at least two months before trying to conceive, and tirzepatide at least one month. We build that gap into your plan rather than leaving you to discover it at the end.

A pre-conception plan should also review folic acid, diabetes treatment, blood pressure medicines, nutritional status and any relevant long-term condition.

Blood samples for reproductive hormone assessment

What we look at

For women, this can include menstrual and ovulation history, PCOS features, thyroid health, glucose regulation and previous fertility investigations. For men, it may include metabolic health and carefully interpreted hormone tests alongside formal semen analysis through the right pathway.

We review medicines and supplements because some influence hormones, weight or pregnancy planning.

  • Ovulation and menstrual history
  • Thyroid and glucose health
  • Male hormone assessment where indicated
  • Nutrition and medicines before conception

What can change

Where weight reduction is appropriate, a modest change may improve ovulation or metabolic health for some people. It cannot guarantee conception, and care should avoid harmful pressure or an arbitrary target without clinical purpose.

Local NHS fertility funding criteria can include BMI thresholds, but these vary by area and are commissioning rules. We help patients understand the distinction between eligibility and individual clinical care.

We can communicate with your own doctor, gynaecologist, andrology service or fertility clinic to reduce conflicting advice.

The aim is to improve health while avoiding unnecessary delay to appropriate fertility investigation and treatment.

What happens next

The next step

Understanding what is driving your weight takes a proper assessment — your history, the other conditions you live with, the medicines you already take, and what has been tried before.

Where obesity is complex, Dr Raj may recommend the Specialist Weight Management Plan: our most intensive option, for the most complex cases. Not everyone needs it. For others, consultations and review alone are enough, and what you are offered depends on what is actually going on.

Care is delivered through our London and Chennai clinics.

Fertility, Hormones & Weight FAQs

For some people it may improve ovulation, metabolic health or treatment readiness, but the effect depends on the cause and cannot guarantee conception.

We assess relevant endocrine and metabolic factors, while semen testing and specialist fertility investigations remain essential parts of the wider pathway.
