Fertility Testing for Both Partners: The Complete Guide
The fertility workup is your starting point — for both partners. Understanding what's being tested, what the numbers mean, and what comes next takes the mystery out of the process.
A complete fertility evaluation includes bloodwork, imaging, and a semen analysis. Male factor is involved in 40–50% of infertility cases, so testing both partners from the start saves time and avoids missed diagnoses.
Why Test Both Partners
Infertility is roughly split: about one-third female factor, one-third male factor, and one-third combined or unexplained. Yet many couples start with only the female partner being evaluated. A semen analysis is one of the simplest, least invasive fertility tests — and it identifies the cause in nearly half of all cases. Testing both partners simultaneously avoids months of delay.
The Female Fertility Workup
Bloodwork (Hormonal Panel)
These are typically drawn on cycle day 2–4 (early in your period):
| Test | What It Measures | Normal Range | What Abnormal Means |
|---|---|---|---|
| FSH | Ovarian stimulation effort | <10 mIU/mL | Elevated (>15): diminished reserve |
| AMH | Egg quantity marker | 1.0–3.5 ng/mL (age-dependent) | Low: fewer eggs remaining |
| Estradiol (E2) | Baseline estrogen | <80 pg/mL on day 2–4 | Elevated: may mask FSH reading |
| TSH | Thyroid function | 0.5–2.5 mIU/L for fertility | Subclinical hypothyroidism |
| Prolactin | Pituitary hormone | <25 ng/mL | Elevated: can suppress ovulation |
| Progesterone (day 21) | Confirms ovulation | >3 ng/mL | Low: anovulation suspected |
Imaging: Antral Follicle Count
A transvaginal ultrasound on cycle day 2–5 counts small follicles visible on each ovary. This combined with AMH gives the best picture of ovarian reserve. Typical AFC: 10–20 follicles (both ovaries combined) in your early 30s.
Tubal Evaluation: HSG or SHG
HSG (hysterosalpingogram) is an X-ray with dye injected through the cervix. It shows whether fallopian tubes are open or blocked and identifies uterine cavity shape. It takes about 10 minutes and can cause cramping. Some studies suggest a slight fertility boost after HSG, possibly from the dye “flushing” the tubes.
SHG (sonohysterogram) uses saline and ultrasound to evaluate the uterine cavity. It's better for detecting polyps, fibroids, and other structural issues but doesn't assess tubal patency as reliably.
The Male Fertility Workup
Semen Analysis
The cornerstone of male fertility testing. A sample is collected (2–5 days of abstinence beforehand) and evaluated for:
| Parameter | WHO Reference Value (2021) | What It Means |
|---|---|---|
| Volume | ≥1.4 mL | Amount of ejaculate |
| Concentration | ≥16 million/mL | Sperm per milliliter |
| Total motility | ≥42% | Percentage that are moving |
| Progressive motility | ≥30% | Percentage swimming forward |
| Morphology | ≥4% normal forms | Percentage with normal shape |
One abnormal result doesn't define you. Semen quality varies from sample to sample. An abnormal result should be repeated 2–4 weeks later for confirmation. Illness, stress, heat exposure, and medication can all temporarily affect results.
When Additional Male Testing Is Needed
If the semen analysis is significantly abnormal, further workup may include hormonal testing (FSH, testosterone, LH), a scrotal ultrasound (to check for varicocele), DNA fragmentation testing, and possibly genetic testing (karyotype, Y-chromosome microdeletion).
What Happens After Testing
With results in hand, your doctor can develop a treatment plan matched to your specific diagnosis:
Everything normal (unexplained infertility): Typically start with timed intercourse or IUI with ovulation induction.
Ovulatory dysfunction (PCOS, irregular cycles): Ovulation induction with letrozole as first-line treatment.
Tubal factor: IVF, since it bypasses the tubes entirely.
Male factor: Depending on severity — IUI for mild issues, IVF with ICSI for moderate-to-severe.
Diminished ovarian reserve: Earlier IVF may be recommended to maximize egg yield.
Bring your partner to the first consultation and start both workups simultaneously. The semen analysis is quick, inexpensive ($100–$300), and identifies the cause in nearly half of cases. Starting with only the female workup delays answers by months.
