Sperm that cannot swim (poor or zero motility) prevents natural conception and IUI — but with ICSI, motility becomes completely irrelevant. The embryologist selects and injects even an immotile sperm directly into the egg. Mother Hospitals Hyderabad, 5,000+ ICSI cycles.
Understanding your semen analysis result
| Parameter | Normal (WHO 2021) | Meaning if Below Normal |
|---|---|---|
| Total Motility | ≥42% | Asthenospermia — poor swimming ability overall |
| Progressive Motility (PR) | ≥30% | Sperm cannot swim forward effectively |
| Non-Progressive Motility | Part of total motility | Sperm move but in circles or abnormally |
| Immotility | <58% immotile | High immotility rate — necrospermia if all immotile |

ICSI completely bypasses the need for sperm to swim. The embryologist selects and injects a single sperm directly into the egg — making motility a non-issue. Even with 0% progressive motility, ICSI can achieve fertilisation and pregnancy. Mother Hospitals has completed 5,000+ ICSI cycles.
CoQ10 (600mg/day) directly powers mitochondria in the sperm tail — improving motility. Vitamin E, L-Carnitine (improves progressive motility), Zinc, and Selenium reduce oxidative damage. Requires 3 months minimum to show results. Can improve motility by 15–25% in responsive cases.
Varicocele is the most common and correctable cause of poor motility. Surgical repair (varicocelectomy or microscopic varicocelectomy) reduces scrotal temperature and oxidative stress, often significantly improving motility within 6 months. Recommended before IVF for clinically significant varicocele.
In necrospermia (all sperm appear immotile), the HOS (hypoosmotic swelling) test identifies which sperm are alive but not moving — their tails swell in hypoosmotic solution. Only live sperm swell. These alive-but-immotile sperm can be safely used in ICSI.
Testicular sperm has not yet passed through the epididymis, where motility-impairing damage can accumulate. In true necrospermia or very poor ejaculated sperm, TESA retrieves immature testicular sperm that is then used in ICSI — often with better outcomes than severely immotile ejaculated sperm.
For mild asthenospermia (total motility 30–42%), IUI — intrauterine insemination — concentrates and places the best-moving sperm directly into the uterus, reducing the distance sperm must swim. However, ICSI is recommended for moderate or severe motility issues as it eliminates swimming distance entirely.
