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...
