There are two types of in vitro fertilization techniques; IVF itself and intracytoplasmic sperm microinjection. The main indication for IVF is a motile sperm count above 3 million. Therefore, any semen sample below this count will be indicative of ICSI (severe male failure).
Other possible indications for ICSI would be a previous IVF fertilization failure, semen samples with teratozoospermia or patients requiring preimplantation genetic diagnosis treatment.
