Final answer:
Intracytoplasmic sperm injection (ICSI) is a procedure used to assist with conception in cases of severe male infertility, where a single sperm is injected directly into the egg, typically as part of in vitro fertilization (IVF) treatments.
Step-by-step explanation:
A sophisticated procedure used in cases where a man has severe infertility problems is called intracytoplasmic sperm injection (ICSI). In this type of assisted reproductive technology, a single sperm is injected directly into an egg. This method can be used when there is a very low sperm count or when the sperm are not motile enough to fertilize the egg on their own.
After ICSI, the egg is monitored for cell divisions to ensure the viability of the zygote before one or more embryos are implanted into the woman's uterus. Fertilization takes place outside the body, a method also known as in vitro fertilization (IVF). If successful, the procedure can lead to the implantation of the fertilized egg and subsequent pregnancy.
