Question

select the correct answer.
how does in vitro fertilization work?
a. the sperm are \washed\ to remove the unhealthy ones and then are placed directly in the uterus.
b. several eggs from a woman and sperm from a man are put together in a lab situation.
c. medicines that boost ovulation are used to stimulate the ovaries to release multiple eggs at one time.

Explanation:

In vitro fertilization (IVF) involves combining eggs from a woman and sperm from a man in a laboratory setting to facilitate fertilization. Option A is incorrect as sperm aren't "washed" to remove unhealthy ones for direct placement in the uterus in the main IVF process. Option C describes ovulation induction for multiple eggs, not the core IVF fertilization step. Option B correctly states the lab - based combination of eggs and sperm.

Answer:

B. Several eggs from a woman and sperm from a man are put together in a lab situation
