Investigations of Male Infertility:
General:
- Blood for TC, DC, Hb%, ESR, VDRL, TPHA, GET, Blood sugar.
- X- ray chest and pelvis.
Special:
- Prostatic smear & culture to exclude gonorrhea,
- Semen analysis,
- Testicular biopsy,
- Hormone analysis: Estimation of FSH, LH, testosterone, TSH, T3, T4 & Prolactine,
- Karyotype will exclude Klinefelter’s syndrome,
- Immunological test Mauntoux test,
- Urethral discharge for gram staining and C/S,
- X-ray of sella turcica for pituitary enlargement.
Other tests:
- Test for anti-sperm antibodies,
- Test for fertilizing capacity of spermatozoa,
- In vitro test of cervical mucus preparations,
- Sperm penetration assay (hamster egg penetration assay).

Diagnosis of Female Infertility:
History:
- Age, duration of marriage, history of previous marriage with proven fertility if any.
- In utero DES exposure.
- History of pubertal development.
- Present menstrual cycle characteristics (length duration, molimina).
- Contraceptive history eg. IUCD.
- Prior pregnancies, outcomes.
- Previous surgeries, especially pelvic.
- Prior infection e.g. appendicitis, peritonitis, TB in any site, gonorrhea, chlamydia infection.
- H/O abnormal Pap smear, treatment.
- Drugs: mefenamic acid taken for mittelschmerz pain may interfere with ovulation.
- Sexual problems such as dyspareunia and loss of libido are to be enquired.
- General health (diet, weight, stability, exercise patterns, review of systems).
Examination:
This should cover all systems with particular attention to the reproductive system. In regard to reproductive system look especially for assessment of the vagina; the size position & mobility of the uterus and any enlargement or fixation of the appendages in the woman.
General examination:
- Obesity,
- Weight loss,
- Hirsuitism,
- Goiter.
Systemic examination:
- HTN, Organic heart disease, chronic renal failure, endocrine disorder etc.
Gynaecological examination:
- Hymenal patency,
- Evidence of vaginal infection,
- Cervical tear,
- Undue elongation of the cervix,
- Uterine size, position, mobility,
- Presence of adenexal masses.
Investigations of Female Infertility:
General:
- Blood for TC, DC, Hb%, ESR, VDRL, TPHA, GET, Blood sugar,
- X- ray chest and pelvis,
- Urine analysis.
Special investigation:
1. To see evidence of ovulation:
- Basal body temperature,
- Cervical mucus test,
- Estimation of serum progesterone,
- Serial estimation of LH level,
- Laparoscopy.
2. To see the tubal pathology:
- Hysterosalpingography,
- Laparoscopic dye test,
- Tubal insufflation test.
3. To see the uterine pathology:
- Hysterosalpingography.
4. To see the cervical pathology:
- Post coital test.
- Sperm cervical mucus contact test.
5. Immunological test.
6. Hormonal assays- FSH, LH, prolactine, oestrogen, progesterone, testosterone.
