Suggest Treatment For Infertility While Having PCOS
Ovulation
Detailed Answer:
Mid-luteal progesterone is best interpreted in women with regular cycles every 25 to 35 days. We generally recommend 7 days prior to the next cycle as the ideal date for blood sample collection for Serum Progesterone.
With your wife's 40 day intervals between menstrual cycles, there is inadequate reliability of this test.
Secondly, regarding the level of 8.9 it is in the grey zone. In other words it cannot be stated with confidence whether ovulation occurred or not. The reason is that published literature and practice shows that values below 5 are suggestive of lack of ovulation while results more than 10 are indicative of the occurrence of ovulation. However, values between 5 and 10 are challenging to interpret as they can indicate either possibility.
If the diagnosis of PCOS is accurate in her case, then she will be best served by consulting a Reproductive Endocrinologist in-person for management of fertility related matters
