Research indicates a relationship between sperm fertilization success and the severity of sperm morphological abnormalities in in vitro fertilization (IVF) procedures, where selected motile sperm are placed with egg cells for natural fertilization. However, in microinjection methods such as intracytoplasmic sperm injection (ICSI), embryologists select sperm with the most optimal shape and structure using specialized techniques. Therefore, with the exception of specific morphological abnormalities like globozoospermia, where sperm fertilization ability is severely compromised, the negative impact of sperm morphology on the overall success of in vitro fertilization treatment is generally less than commonly perceived.
