|Infertility Resident Survival Guide Microchapters|
Infertility is defined as a failure to conceive after one or more years of unprotected intercourse. Infertility is divided broadly into primary and secondary infertility where primary infertility is failure to conceive and secondary infertility is failure to conceive after a previous pregnancy. Multiple factors play a role in conception and infertility such as healthy spermatozoa, regular ovulation, patent fallopian tubes, normal uterine cavity etc.
Common causes of female infertility are listed below.
- Turner's syndrome
- Mayer-Rokitansky-Kuster-Hauser syndrome
- Kallmann syndrome
- Primary ciliary dyskinesia
- Polycystic ovarian syndrome
- Congenital adrenal hyperplasia
- Hypogonadotropic hypergonadism
- Pelvic inflammatory disease causing adhesions and endosalpingeal damage
- Previous tubal surgery
- Tubal endometriosis
- Congenital uterine anomalies such as septate uterus
- Uterine hypoplasia
Shown below is an algorithm summarizing the diagnosis of female infertility according to the American College of Gynecology and Obstetricians 2019 Committee opinion on Infertility workup for the woman's health specialist and Evaluation, Global infertility guidelines published in 1992 by the WHO, updated in 2012, and The treatment of infertility guidelines by the American Family Physician. 
Abbreviations: STD - Sexually transmitted disease, FSH - Follicle stimulating hormone, LH - Luteinizing hormone, TSH - Thyroid stimulating hormone, CT - Computed tomography, MRI - Magnetic resonance imaging, IVF - In vitro fertilization
|Couple with infertility|
Detailed history including
❑ Any history of abdominal or pelvic surgery?
❑ Menstrual history
❑ History of contraceptive use
❑ Obstetric history
❑ Any history of diethylstilbestrol exposure
❑ Frequency of intercourse
❑ Any history of STDs in either partner
❑ History of acne, hirsutism or recent weight changes
❑ Height, weight and BMI
Head and neck examination for
❑ Webbed neck
❑ Epicanthal fold
❑ Presence of any neck swellings
❑ Breast examination for any swellings or nipple discharge
❑ Any swellings in the abdomen
Thorough gynecological exam including
❑ Distribution of pubic hair
❑ If there is presence of any clitoral enlargement

Bimanual exam might detect the presence of

|Normal semen analysis|
|Ovarian causes||Endometrial causes||Cervical causes||Fallopian tube causes|
|Endometrial biopsy on day 21-23||Cervical mucus study/ Sperm cervical mucus contact test|
|Anovulatory cycle||Ovulatory cycle||Progressive motile sperm seen||Sperm antibodies|
|If age is >30 years, work up with all other investigations including day 3 FSH||Occasionally, IgG, IgA or IgM antibodies are found against sperm. Treating these anti-sperm antibodies have not shown an improved outcome in pregnancies. Treatment is along the lines of IVF|
|Non secretory endometrium||Secretory endometrium|
|Luteal phase defect|
|Confirmed by basal body temperature or repeat endometrial biopsy and serum progesterone estimated on 8th day|
|Thorough history and initial investigations|
|Ovulatory causes||Tubal causes||Cervical causes||Endocrinopathies||Uterine causes||Other causes|
Induction of ovulation can be done by
❑ Clomiphene citrate
❑ Purified/recombinant FSH
❑ Gonadotropin-releasing hormone and its analogues
Assisted reproductive techniques such as
❑ In vitro fertilization
❑ cryopreservation of gametes or fertilised embryos
❑ Intracytoplasmic sperm injection
❑ Egg donation via donors
❑ Uncontrolled diabetes must be treated before exploring other options
❑ Hyperthyroidism and Grave's disease causing infertility can be corrected with antithyroid drugs
❑ Hypothyroidism induced infertility is corrected when euthyroid state is achieved
❑ CAH causes infertility which can be corrected with clomiphene and other ovulation induction techniques
ARTs are used when ovulation stimulation fails
❑ Treating infertility in PCOS is a multidisciplinary approach and involves
Glycemic control with metformin
Reduction of weight when applicable
Oral contraceptive pills
Ovulation induction with clomiphene
Antiandrogens such as flutamide and spironolactone for acne and hirsutism
❑ Hyperprolactinemia induced infertility is treated with dopamine agonists such as cabergoline
- Prompt and early treatment of PID must be done to prevent infertility. 
- Effective counseling must be done about male and female components of infertility.
- Educate the patient about toxic effects of nicotine, marijuana, and other drugs and their impact on fertility if the patient is a known user. 
- Risk of ectopic pregnancy, multiple gestations and ovarian hyperstimulation syndrome must be explained.
- Don't ignore the risk of ovarian hyperstimulation syndrome in patients undergoing ovulation induction, particularly in patients who have had PCOS. 
- Don't pursue assisted reproductive technology without first correcting underlying endocrinopathy when present.
