IVF is possible in cases of severe oligospermia and also malformations. IVF is an assisted reproduction technique that can be used to help a woman conceive, even if the man has oligospermia and sperm abnormalities. Strictly speaking, a man with one normal sperm is eligible for IVF. IVF is the common name for in vitro fertilization and embryo transfer, which can be used for infertility caused by factors such as oligozoospermia, hypospermia, and dyszoospermia in men, and blocked fallopian tubes, endometriosis, and other factors in women, in order to achieve the goal of conception. Although the success rate of IVF is low in clinical practice, IVF can also be performed in men with severe oligozoospermia and malformations to achieve fertility through assisted reproductive technology.
