Optimising the management of patients with infertility.
Level 5 - mechanism / opinion, no new human data
Narrative review and expert clinical guidance article without original empirical data or systematic review methodology
What was done
This narrative clinical guidance article outlines common causes, initial investigation strategies, and management principles for couples presenting with infertility in primary care.
What was found
More than 80% of couples where the woman is under 40 years of age will conceive within one year of regular sexual intercourse, and approximately half of the remainder will conceive in the second year, resulting in a cumulative pregnancy rate exceeding 90%. Referral for clinical assessment is recommended after one year of regular unprotected intercourse. Conception takes longer for women with a BMI ≥ 30, and weight gain is advised for women with a BMI < 19 with irregular or absent menstruation. Outlined diagnostic tests include timed mid-luteal serum progesterone for ovulation, serum gonadotrophins (FSH and LH) for irregular cycles, and screening for tubal occlusion (or laparoscopy with dye testing if comorbidities exist).
Why it matters
It outlines basic epidemiological expectations and first-line diagnostic pathways for primary care clinicians managing couples with difficulty conceiving.
Limits
The paper provides broad narrative clinical advice without presenting primary empirical data, study designs, sample sizes, confidence intervals, or a systematic search protocol.
