Polycystic ovarian syndrome (PCOS) is a very common menstrual disorder affecting around 1 in 10 women. It is diagnosed when a woman has two of the three following symptoms: ovaries with many small cysts, a raised level of the male hormone testosterone and irregular periods.

Why is my fertility affected?

The exact cause of polycystic ovarian syndrome is not known; several factors are likely to be involved including insulin resistance and a high level of luteinising hormone. What is known is that one symptom is the abnormal development of the follicles in the ovaries: they often fail to develop fully, causing problems with ovulation and therefore irregular periods. Ovulation is essential to the conception process: a reduction in periods tends to result in reduced fertility.

What are my treatment options?

Polycystic ovarian syndrome is often associated with being overweight or obese. If this is the case, then the first step is to lose weight as this can significantly improve your chances of regular menstruation. After this point, you may be a suitable candidate for fertility treatment or, in some cases, surgical intervention.

During a consultation at the London Clinic, female gynaecologist Miss Amanda Tozer will take your full medical history before conducting a pelvic ultrasound and running blood tests. Diagnosing your individual case, Miss Tozer will then advise you on the most appropriate treatment. Many women with polycystic ovarian syndrome respond well to fertility drugs such as Clomiphene whereby a more predictable window for conception is created by inducing ovulation.

Ovulation is a vital factor when a couple are planning a pregnancy. As the woman ovulates, she releases an egg that can then be fertilised by the sperm; fertilisation cannot occur until the egg is released. Some women do not ovulate regularly, and others do not ovulate at all. Female gynaecologist Miss Amanda Tozer treats many women at The London Clinic, helping them to regulate the ovulation process with ovulation induction, thereby increasing their chances of fertilisation.

What factors influence ovulation?

Stress, weight fluctuations and Polycystic Ovarian Syndrome (PCOS) are common factors in irregular ovulation. Among other issues, can also be caused by disorders of the thyroid or pituitary glands. During an initial consultation, Miss Amanda Tozer will take a full medical history, conduct a physical examination and run tests to inform her diagnosis; these will include an ultrasound of the ovaries and womb and blood tests.

How does ovulation induction work?

The purpose of ovulation induction is to stimulate the ovaries in order to produce a mature follicle and, in turn, egg growth, which creates a predictable window for intercourse. This is achieved most commonly by using Clomiphene, a mild fertility drug which comes in tablet form. Women take Clomiphene from day 2 to day 6 of a bleed and usually have a scan on day 10 to ensure that ovulation is going to occur and that the ovaries are not over-stimulated. If a woman does not respond to Clomiphene, daily injections of Gonadotrophins may be appropriate; in this case, scanning will be necessary to avoid over-stimulation of the ovaries.

Each woman responds differently to ovulation induction and therefore needs careful monitoring and attention. Amanda Tozer is a highly qualified female gynaecologist with many years’ experience of helping women with fertility problems. At Miss Tozer’s London clinic, you will receive individual care to guide you through this process.
