Documenting your ovulation is always the first step in our infertility investigation


First and foremost, we want to understand and correctly identify the nature of the problem; is it ovulatory dysfunction, tubal factor infertility (obstruction of the fallopian tubes), a pelvic factor, male infertility or unexplained infertility?

A normal menstrual cycle usually lasts between 21 and 35 days. There are a number of ways to document ovulation. The simplest is to chart your body temperature every day, creating a basal body temperature curve. An oral temperature should be taken when you wake up, before you get out of bed or do anything else. (Computerized basal temperature curves)

Another way is to take a blood sample about 7 days before menstruation to measure the level of plasma progesterone.

If menstrual cycles are less than 21 or over 35 days, an ovulatory problem is very likely. An additional investigation is then required to identify the underlying cause of anovulation. Various hormones may be prescribed:

  • FSH, LH, Prolactin, TSH
  • DHEAS, testosterone, 17-hydroxyprogesterone
  • Human chorionic gonadotrophin hormone commonly referred to as a pregnancy test
  • AMH

If anovulation associated with excess weight is suspected, additional tests will be considered:

  • HbA1c or 75g oral glucose tolerance test with blood samples taken at 0, 60 and 120 minutes
  • Lipid profile test
