Which woman will only be able to conceive using in vitro fertilization? Karen, whose fallopian tubes are permanently blocked (or missing) Rai, who is having trouble carrying a child to term Ruth, who is over the age of 40 Latasha, who is having trouble ovulating

Answer: Karen

Explanation:

Because the fertilization of an egg by a sperm occurs in the fallopian tubes, Karen will not be able to conceive without In Vitro Fertilization (IVF).

In Vitro Fertilization (IVF) is a process that involves fertilizing an egg (oocyte) with a sperm outside the woman's body. If the fallopian tubes are only partially blocked, a woman has more options such as having a surgery to remove scar tissue or create another opening.

A woman who is having trouble ovulating or not ovulating at all can still conceive through ovulation induction, a chemical way of stimulating the release of an oocyte.

Ruth, who is having trouble carrying a child to term can employ the services of a surrogate mother.
