in vitro fertilization
体外受精 is a medical procedure used to help couples conceive a child. It involves extracting eggs and sperm, fertilizing them outside the body in a laboratory setting, and then transferring the resulting embryos back into the uterus. This method is often used when couples face difficulties in natural conception due to various factors such as age, health issues, or infertility problems.
