Basal body temperature
- Basal body temperature is measured just on waking up in the morning. Usually there is a biphasic pattern in temperature in ovulatory cycles. There is no rise in temperature in anovuluatory cycles. [1]
- This is measured as a 0.2-0.5 degrees Celsius rise in temperature after ovulation which is sustained till the beginning of the next cycle.
- There is a drop pf 0.2 degrees Celsius right before the rise in temperature. This coincides with the Luteinizing hormone surge.
- Basal body temperature recording is a tedious process and involves recording of temperature at the same time everyday.
- Temperature changes can also be attributed to other causes such as fever, cold or hot temperatures and usage of air conditioners.
Hormone estimation
- Serum progesterone is measured on day 8 and 21 in the cycle.
- Increase in serum level from >1 ng/ml-6 ng/ml suggests ovulation
- In anovulatory cycles and irregular menstrual cycles, this increase might not be appreciated.
- Serum Luteinizing hormone is measured daily to look for a mid-cycle surge.[2]
- Ovulation occurs around 36 hours after LH surge.
- Serum estradiol is measured around the same time as the LH surge
Hysterosalpingography
- Hysterosalpingography is done to detect the continuity between cervical canal and fallopian tubes. [3]
- This test can detect the side on which obstruction is present, if any.
- It can also detect congenital abnormalities, synechiae and presence of fibroids etc.
Pelvic ultrasound
- Pelvic ultrasound can predict ovulation with higher accuracy than basal body temperature.
- It can also detect the cyclical changes in uterine endometrium. These changes are absent in anovulatory cycles.
- The position of uterus, presence of fibroids, cystic changes in ovaries, congenital anomalies in the genital tract can be detected via pelvic ultrasound.
Laparoscopy
- Laparoscopy is the best method to detect any abnormalities in the fallopian tubes.[4]
- Tubal potency, motility, adhesions, etc can be visualised directly.
- Changes in the ovary such as cysts, endometriosis are also see.
- If any adhesions or synechiae are present, adhesiolysis can be attempted during the diagnostic procedure itself.
Endocrinopathies
- Serum TSH, T3, and T4 must be done in all patients to check for hypothyroidism or hyperthyroidism.
- Hyperprolactinemia is evidenced by an increase in serum prolactin. Prolactin is also increased in hypothyroidism.
- Serum testosterone, dehydroepiandrosterone sulphate may be elevated in some cases, pointing towards congenital adrenal hyperplasia.
- Fasting and post prandial blood sugar levels must be done in cases where PCOS is suspected to rule out insulin resistance.
