Fertility Testing 101: The Labs, Scans, and Questions That Could Save You Months When TTC
Fertility testing can feel overwhelming. Knowing which tests to ask for—and when—can help you avoid delays and frustration.
This guide outlines a thorough testing roadmap, drawing on expert sources like Dr. Aimee's clinical protocols, Rebecca Fett’s research, and top fertility specialists. Use it to advocate for the care you deserve.
🩺 Most Testing Can Be Done in 4–5 Strategic Appointments
🩸 One main blood draw (Day 3)
🧫 One follow-up blood test (Day 21)
🖥️ One imaging visit
🧪 One semen sample
🧬 Advanced testing only if needed
✅ Standard Fertility Tests (Usually via OB/GYN)
For Women:
AMH, FSH, LH, TSH, Vitamin D (basics of egg reserve and thyroid function)
Prolactin, Estradiol (cycle hormones)
Pelvic ultrasound (ovaries, follicles, uterine lining)
Saline Infusion Sonogram (SIS), HSG (checks if fallopian tubes are open)
Complete Blood Count (CBC) (Anemia is common in women and can significantly impact fertility)
Basic Metabolic Panel (BMP) (Kidney function, electrolytes; often done alongside other blood work)
-
➕ Additional Considerations
Blood type and antibody screen (Identifies potential Rh incompatibility)
Rubella & Varicella titers (Confirms immunity to pregnancy-affecting infections)
Pap smear & STD screening (Basic reproductive health screen to rule out infections)
Blood pressure & lipid panel (General health markers that influence fertility, hormone balance, and pregnancy outcomes)
For Men:
Semen analysis (count, motility, morphology—request a WHO-compliant lab)
Testosterone (total and free) (This is typically included in basic male fertility workups)
Basic Metabolic Panel (BMP) (Kidney function, electrolytes; often done alongside other blood work)
-
➕ Additional Considerations
Blood pressure & lipid panel (General health markers that influence fertility, hormone balance, and pregnancy outcomes)
🧪 Often Overlooked but Highly Insightful Tests
For Women:
Day 21 progesterone (confirms if and when you're actually ovulating)
Vitamin B6 (Important for luteal phase and hormone balance)
Celiac disease screening (Undiagnosed celiac can cause fertility issues and pregnancy complications)
-
➕ Additional Considerations
Omega-3 fatty acids (Increasingly recognized for egg quality and inflammation)
Coenzyme Q10 (Especially relevant for egg quality in women over 35)
For Men:
LH & FSH (To assess pituitary-testicular function)
Prolactin (Elevated levels can suppress testosterone)
🔬 Sperm DNA Fragmentation (can be elevated even when standard sperm tests look “normal.” Offers deeper insight into sperm quality, especially in unexplained infertility or loss)
Celiac disease screening (Undiagnosed celiac can cause fertility issues and pregnancy complications)
-
➕ Additional Considerations
Optional Add-On: Genetic Carrier Screening (inherited condition screening)
For Both:
Cortisol (AM blood draw) (chronic stress can silently disrupt fertility)
Free testosterone, DHEA-S (hormonal imbalances like PCOS or adrenal issues)
Thyroid antibodies (TPOAb, TGAb) (subclinical thyroid problems are common and often missed)
Insulin and HbA1c (metabolic health)
CRP and homocysteine (chronic inflammation can block conception)
Vitamin B12 and Folate (especially methylated forms—key for early development)
Zinc, selenium, magnesium (critical for hormone production and sperm quality)
🔬 Next-Level Fertility Testing (via Reproductive Endocrinologists)
🔬 Emerging 🧪 Experimental ⚠️ Controversial 🧭 Case-by-case
-
For Women:
🔬 ReceptivaDx (detects a marker of inflammation called BCL6 in the uterine lining, which can indicate silent endometriosis. It’s done via an endometrial biopsy, typically between cycle days 7–11)
🧪 EMMA/ALICE (endometrial microbiome & inflammation testing)
Endometrial biopsy (checks if the uterine lining is receptive)
⚠️ Igenomix ERA (endometrial Receptivity Analysis: A genetic test that helps determine the optimal timing for embryo implantation by analyzing the endometrium’s receptivity. This personalized approach can improve IVF success by pinpointing the best window for embryo transfer)
Laparoscopy or specialized imaging (if endo or structural issues are suspected)
Autoimmune panel (ANA, antiphospholipid antibodies) (for recurrent pregnancy loss)
Karyotyping (in cases of recurrent loss or IVF failure)
Hysteroscopy (direct visualization of the uterine cavity to detect polyps, fibroids, or adhesions)
Thrombophilia panel (assesses inherited blood clotting disorders)
Recurrent miscarriage panel (comprehensive loss workup)
🧭 Natural Killer (NK) cells testing (for recurrent implantation failure)
-
➕ Additional Considerations
🧪 Food sensitivity/allergy panels (Some specialists use these for unexplained infertility)
🧭 Heavy metals testing (Mercury, lead can affect fertility)
Comprehensive stool analysis (Gut health connection to fertility is emerging)
-
For Men:
🧭 Sperm DNA fragmentation (not yet part of routine testing in most fertility clinics, but valuable for couples with unexplained infertility, ART failure, or poor embryo development)
Genetic screening (for heritable disorders, especially with low sperm parameters)
Y-chromosome microdeletion testing (if very low sperm count or azoospermia)
Karyotyping (can be relevant for both partners if there’s recurrent miscarriage)
Estradiol (can be elevated in men with certain conditions, affecting fertility)
Scrotal/testicular ultrasound (to check for varicoceles or structural issues)
-
➕ Additional Considerations
Sperm antibodies (Can cause unexplained infertility)
Advanced sperm testing (Oxidative stress, mitochondrial function - beyond basic DNA fragmentation)
Post-ejaculatory urinalysis (To check for retrograde ejaculation)
🧪 Food sensitivity/allergy panels (Some specialists use these for unexplained infertility)
🧭 Heavy metals testing (Mercury, lead can affect fertility)
Comprehensive stool analysis (Gut health connection to fertility is emerging)
Whole-Health Fertility: More Than Just Reproductive Health
Fertility isn’t only about ovaries, eggs, or sperm. Your gut, stress levels, sleep, nutrient status, and toxin exposure can all influence your ability to conceive. At WOVA, we take a systems-based approach—going beyond reproductive labs to help uncover hidden blocks.
Because when your whole body is in sync, your fertility has its best chance.
