Investigation
Examinations
- General physical examination to see the fragments of amenorrhoea
Abdominal examination:
- Masses felt in the hypogastrium could be arising from the pelvic region
Per speculum examination:
- The distribution of hair pattern in the external genitalia
- Inspection of vaginal mucosa to detect abnormalities such as deficiency of oestrogen or the presence of infection
- Cervical abnormalities should be ruled out like cervical stenosis
Pelvic examination:
- Various pelvic pathologies like fibroids, adnexal masses, tenderness or pelvic nodules indicative of infection or endometriosis, uterine defects (such as absence of the vagina and uterus, Presence of vaginal septum, etc) can be detected on bimanual examinationBMI
Increased BMI (>28) found to be associated with
- Hyperinsulinemia
- Oligomenorrhoea
- Anovulation
- PCOS
Basal Hormone Evaluation
- Usually done between the third and fifth day of the menstrual cycle – Hormone levels vary the least during this period in the cycle. Irregular hormone levels in this phase suggest a disorder in follicular maturation
- Elevated FSH indicates diminished ovum reserve
- Elevated LH deteriorates oocyte quality
- Serum progesterone on D21-D23 of a 28-day cycle at a level of 10 ng/mL indicate adequate ovulation and adequate luteal phase
- TFT (Thyroid Function test)
- Serum prolactin and androgen levels – elevated levels suppress ovulation
- Antimullerian hormone (AMH) - For quantitative prediction of ovarian reserve
Ultrasonography
- To detect patency of uterus and ovary
- Follicular study to confirm ovulation (Dominant follicle is 17 mm in diameter, Diagnosis of leutinized unruptured follicle can be diagnosed)
Endometrial biopsy
- 2 days prior to the onset of cycle
- A secretory endometrium and subnuclear vacuolation is pathognomic of ovulation
- Endometrium showing 2 days lag is suggestive of LPD(Luteal phase defect)
- Bacteriological evaluation to rule out tuberculosis
Hysterosalpingogram
- To test the tubal patency
- Usually done on 7th -10th day of a cycle
Hysteroscopy
- To assess the pelvic organs and tubal patency
Mandatory when HSG reveals intrauterine lesions like
- Fibroids
- Endometrial polyps
- Congenital uterine anomaly
- Intrauterine adhesions
- Women undergoing IVF
- Failure of implantation after three cycles
Laparoscopy
Mandatory in the presence of
- Pelvic diseases
- Endometriosis
- Unexplained infertility
- Tubal block in HSG
Ovarian factors evaluation
- Follicular study
- Serum progesterone level on 21st day of the cycle
- Clomiphine citrate challenge test
- USG to diagnosis PCOD
- Basal body temperature charting
