The fertility evaluation: what a complete workup actually tells you

Before any treatment is recommended, a fertility evaluation tries to answer one question: what is keeping pregnancy from happening? Most workups take three to four weeks and one cycle to complete. Knowing what is being checked, and why, makes the conversation with your doctor sharper.

The four pillars of a complete workup

A modern fertility evaluation tests four things in parallel: ovarian reserve, ovulation, the anatomy of the uterus and tubes, and the male partner’s sperm. Skipping any one of these means treating with incomplete information.

Pillar 1: ovarian reserve

An AMH blood test plus an antral follicle count on transvaginal ultrasound establishes how many eggs your ovaries are likely to recruit per cycle. FSH on cycle day 2 or 3 adds a third signal. None of these measure egg quality, which is age-driven and currently invisible to all available tests.

Pillar 2: ovulation

Are you ovulating, and if so, when? A regular 25 to 35 day cycle is reassuring. Where it is irregular, a mid-luteal progesterone draw or LH surge tracking confirms or refutes ovulation. PCOS, thyroid disease, and elevated prolactin are the common culprits when ovulation is disordered.

Pillar 3: anatomy

A hysterosalpingogram (HSG) or sono-HSG checks whether the fallopian tubes are open and the uterine cavity is normal. A blockage on one or both sides changes everything that comes next. Hysteroscopy is reserved for when imaging suggests a polyp, septum, or adhesion that needs direct visualisation.

Pillar 4: male partner

A semen analysis on a sample collected after 2 to 5 days of abstinence. The four numbers that matter are volume, concentration, motility, and morphology. Always confirm with a repeat at 2 to 3 months, because a single sample reflects only the past 72 days of sperm production.

What the evaluation cannot tell you

Two things, mainly. First, egg quality – which is the dominant variable in age-related infertility. Second, the why behind unexplained cases. About one in four couples will finish a complete workup with no clear obstacle, and that label, while frustrating, is itself useful information.

Questions worth asking your doctor

• Have we covered all four pillars, or are there parts of the workup we have skipped?
• Given my numbers and my partner’s analysis, what is the probable diagnosis – and is there any second-tier test that would meaningfully change the plan?
• How long are these results valid? Should AMH or semen analysis be repeated before a treatment cycle?
• Given our age and timeline, what would you do in our situation?
