How IUI works in low-count contexts
IUI processes semen to concentrate motile sperm and places prepared sample closer to ovulation timing, improving chances in selected cases.
Limits to understand
IUI is not ideal for severe male-factor infertility. For very low counts or poor motility, ICSI is often a more effective path.
Practical expectation setting
Clinics should set cycle expectations early and define transition criteria to IVF/ICSI to avoid repeated low-yield attempts.
