Ovulation / Egg Problem

Ovulation / Egg Problem | Birmingham fertility CentreRegular periods usually indicate that you are ovulating most of the time. This can be confirmed by a blood test to check the hormone Progesterone taken a week before your next period is due.

Irregular periods (more than 7 days variation in the menstrual cycle) may indicate that there is a problem with ovulation. Polycystic Ovary Syndrome is the commonest cause of absent or infrequent ovulation and is diagnosed in 85% of women with ovulation problems. In addition there may be ovulation disorders due to other hormonal conditions such as raised prolactin and rarely with thyroid under or over activity, or related to weight and exercise.

The other cause encountered may be due to an unexpected low store of eggs in the ovaries called low ovarian reserve. This can be related to your age, though this can be seen unexpectedly in younger women. Sometimes this may be related to current or previous medication or treatment such as chemo or radio therapy. Premature ovarian failure or premature menopause before the age of 40 is another cause of absent ovulation.

Full assessment is required to find the cause of infrequent or absent ovulation by appropriately timed blood tests to measure specific hormones, and ultrasound scan. Treatment may involve simple strategies such as ovulation induction with Clomid, or more complex treatment such as IVF, depending on the cause.
