test to measure serum progesterone in the mid luteal phase of their cycle (day 21 of a 28-day cycle)
to confirm ovulation even if they have regular cycles. Women with prolonged irregular menstrual
cycles should be offered a blood test to measure serum progesterone. Depending upon the timing of
menstrual periods, this test may need to be conducted later in the cycle (for example day 28 of a 35-
day cycle) and repeated weekly thereafter until the next menstrual cycle starts. Women with irregular
menstrual cycles should be offered a blood test to measure serum gonadotrophins (FSH and LH).
discuss the investigation of suspected tubal and uterine abnormality
Women who are not known to have comorbidities (such as pelvic inflammatory disease, previous
ectopic pregnancy or endometriosis) should be offered hysterosalpingography (HSG) to screen for
tubal occlusion. As this is a reliable test for ruling out tubal occlusion, and it is less invasive and makes
more efficient use of resources than laparoscopy.
