Correct answer: A — Semen analysis
Semen analysis is the best answer because the vignette is testing Male factor infertility and the recommended approach is consistent with NICE CG156. The other tests may be useful in different pathways, but they would not be the most direct first investigation for this presentation. Specifically, Transvaginal ultrasound scan; Request hysteroscopy as the first test; Serum prolactin; Speculum examination would be suboptimal in this scenario. The first investigation should answer the immediate clinical question and follow the relevant UK pathway.
