After reading the paragraph below, answer the questions that follow.
In a study of patients seeking assisted reproductive technology, researchers examined the level of FSH in each patient as well as the average number of oocytes they were able to retrieve. Here is an approximation of the data.
| | Younger than 33 | Older than 33 but younger than 37 | Older than 38 but younger than 41 | Older than 41 |
| FSH levels | baseline = 100% | 112% | 117% | 122% |
| Oocytes retrieved | 8.8 | 7.5 | 4.7 | 3.2 |

Why would researchers working with assisted reproductive technology be particularly interested in levels of FSH as opposed to other hormones?
◦ FSH is necessary for secondary oocytes to mature.
◦ FSH is the hormone that prepares a woman's body for pregnancy.
◦ FSH levels are an indicator of a woman's general state of health.
◦ FSH helps the secondary oocyte maneuver through the oviduct.
