Every treatment journey begins with an initial consultation with one of our medical consultants. This usually lasts about an hour, which allows plenty of time to discuss in detail both your medical histories and the implications of assisted reproduction for each of you.

We will identify and discuss in great detail the fertility treatment options most suitable for you, with your particular circumstances in mind. We will offer you our expert opinion and point out everything you need to consider when you are making your decision, including the risks involved and the chances of success under your circumstances.

If you would like to go ahead, we may be able to begin your treatment as early as your next menstrual cycle, provided that your fertility assessment (AMH tests and semen analysis) and screening tests (HIV, hepatitis B and C, etc) are completed and the results available for consideration.

Fertility and your weight

Your NHS Body Mass Index or BMI calculator is a measure of health, based on an individual’s weight and height.

For women, being underweight, overweight or obese can have a profound effect on ovulation and therefore your ability to conceive. Some women may suffer from hormonal disorders which cause them to ovulate infrequently or not at all. This not only reduces the chances of conceiving naturally but also means fertility treatment, such as IVF, is less likely to be successful.

Infertility is also more prevalent among men with higher BMI values. Male body fat is closely associated with the production of male reproductive hormones.  Too much or too little body fat disrupts hormones and can affect testosterone and oestrogen levels. Any change hormones can affect sperm and its production. Being overweight or obese can reduce a man’s sperm count, and sperm motility and quality.

As a general rule, we don’t recommend starting your IVF treatment until you have a BMI of between 20 and 35. All of our egg donors must have a BMI up to 32.
