Women's age and total motile normal morphology sperm count, but not serum anti-Müllerian hormone level, were significant independent predictors of conception within 1 year. Some of the newer DNA tests available to assess the quality of semen include: If assisted technologies are used, intracytoplasmic sperm injection, ICSI, where a normal sperm is isolated from a semen sample and injected into an egg, may be a good option for men with low morphology scores. When the sperm has a normal shape and size (head & tail) this is referred to as normal sperm morphology. A result of 0 percent NF usually means in vitro fertilization (IVF) may be necessary for conception. Morphology can affect fertility because sperm need a certain shape to be able to penetrate the outer layers of the egg. Having a large number of abnormally formed sperm in a sample and a low NF score are signs of a condition called teratozoospermia.
