InvestigationsDraft: awaiting clinical review

Fertility investigations

What tests are usually offered, and when, if you are having difficulty conceiving.

Overview

NICE recommends that people who have not conceived after a year of regular unprotected sex are offered assessment, or sooner if the woman is 36 or over or there is a known possible cause.

Investigations look at both partners, because male factors contribute in a significant proportion of couples.

What is well established

Core investigations include confirming ovulation (usually with a mid-luteal progesterone test), a semen analysis for male partners, and assessing whether the fallopian tubes are open.
Ovarian reserve tests such as AMH are mainly useful when planning IVF.
Starting folic acid before conception is recommended.

Uncertain or emerging evidence

Many additional tests offered privately have limited evidence of benefit; it is worth discussing whether a test would change your plan.
