Subfertility investigations
- SFA is the first-line, non-invasive male test; a single abnormal result is not sufficient - it should be repeated (a single sample falsely labels ~10% abnormal).
- Mid-luteal (day 21) progesterone confirms ovulation.
- HSG should not be done during menstruation (air embolism risk) and not after day 11 (radiation to a possible early embryo) - best between days 7-14.
- Basal body temperature charting is not recommended to confirm ovulation (the rise is very small).
