Your sperm morphology meets the WHO/Kruger strict normal criteria. This is a reassuring result for male fertility.
Your sperm morphology shows no normal forms, consistent with globozoospermia (round-headed sperm, acrosome absent) or noticeable teratozoospermia. Sperm lacking normal head and tail structure cannot penetrate an egg. Natural conception and IUI are impossible. ICSI is the only viable treatment option.
Seek urgent reproductive medicine evaluation. ICSI with IVF is the only treatment. Genetic evaluation of the sperm defect may be relevant.
Sperm morphology 0% normal forms — globozoospermia or noticeable teratozoospermia; ICSI requiredYour sperm morphology is below the Kruger strict criteria reference range (teratozoospermia). Abnormally shaped sperm cannot penetrate the egg or fertilize normally. Less than 4% normal forms is associated with noticeably reduced natural conception and IUI success rates.
Seek reproductive medicine consultation. ICSI/IVF is typically recommended for noticeable teratozoospermia. Antioxidant supplementation (CoQ10, vitamin C, E) may modestly improve morphology. Lifestyle factors (heat, smoking, toxins) should be reviewed.
Sperm morphology <4% normal forms — teratozoospermia; fertilization capacity noticeably reducedYour sperm morphology is in the borderline-low range. Borderline morphology alone may not very impact fertility, but combined with reduced count or motility it creates a subfertile picture.
Complete full semen analysis. Discuss with reproductive specialist. Antioxidant supplements and lifestyle optimization may help.
Sperm morphology 1–4% — borderline teratozoospermia; fertility impact depends on other semen parametersYour sperm morphology meets the WHO/Kruger strict normal criteria. This is a reassuring result for male fertility.
