Walking into your first infertility clinic visit and not sure what to expect? In this episode, Dr. Valdez-Sinon walks through the definition of infertility, how to take a thorough history for both partners, the key workup for ovulatory, tubal, uterine, and male factors, and when to refer to REI.
Definition
What is infertility?
- Failure to achieve pregnancy after 12 months of regular unprotected intercourse — for patients under 35
- Shorten to 6 months for patients 35 and older
- Anyone 40+ should be seen as soon as they start trying — don't wait
- Immediate evaluation warranted for:
- Oligomenorrhea or amenorrhea
- Known uterine or tubal disease
- Stage III/IV endometriosis
- Resource: ACOG Committee Opinion No. 781 and ASRM guidelines
History & Exam
HISTORY — PATIENT
- Comprehensive medical and surgical history
- Menstrual history — are cycles regular? (regular cycles suggest ovulation, but ~1/3 of regular cyclers can still be anovulatory)
- Full GYN history — pelvic infections, STIs, known fibroids, endometriosis
- Prior pregnancies with previous partners? (establishes primary vs. secondary infertility)
- Ask about: thyroid disease, galactorrhea, hirsutism, pelvic/abdominal pain, dyspareunia
- Family history: developmental delay, early menopause, reproductive problems
- Social history: tobacco, alcohol, recreational drugs
HISTORY — PARTNER
- Obtain medical and reproductive history — pregnancy takes two
- Prior pregnancies with previous partners?
- Intercourse frequency — ideally unprotected sex ~2x/week
PHYSICAL EXAM
- Vitals, weight and BMI — extremes affect fertility
- Thyroid exam; breast exam (look for galactorrhea if indicated)
- Signs of androgen excess — acne, hirsutism, male-pattern hair
- Pelvic exam — uterine size, shape, mobility; adnexal masses or tenderness
Ovarian & Ovulatory Evaluation
COMMON CAUSES
- PCOS — most common cause of ovulatory-related infertility
- Primary ovarian insufficiency (POI)
- Thyroid disease, hyperprolactinemia
WORK-UP
- Mid-luteal progesterone — obtain ~day 21 of a 28-day cycle; value >3 ng/mL suggests ovulation
- For PCOS evaluation: LH, FSH, testosterone
- Thyroid function studies and prolactin as indicated
- Ovarian reserve:
- Antral follicle count on early-cycle ultrasound
- AMH — value L suggests diminished ovarian reserve
- A low AMH does not mean infertility — it only takes one egg. AMH estimates ovarian reserve and responsiveness to gonadotropins for IVF/oocyte preservation.
TREATMENT FOR ANOVULATION
- Ovulation induction with clomiphene (estrogen receptor antagonist) or letrozole (aromatase inhibitor)
Tubal Evaluation
- HSG (hysterosalpingogram) — gold standard for tubal patency
- Radio-opaque dye injected through cervix; X-ray visualizes "fill and spill" through tubes
- Low positive predictive value — non-patency needs follow-up
- Hydrosalpinx: salpingectomy often recommended before IVF — fluid impairs implantation
- Known tubal factor → IVF required for conception
Uterine Evaluation
- Look for: polyps, fibroids, septum, adhesions (synechiae) — >16% of patients with infertility have a uterine abnormality on sono
- Saline infusion sonogram (SIS) — preferred over standa...
