What term is used to describe something pertaining to the organs of reproduction?

The term that refers to something related to the organs of reproduction is "genital." This term encompasses the reproductive organs and structures involved in the processes of reproduction, including the external and internal organs specific to both male and female biological systems.

In contrast, the term "gastric" pertains to the stomach or processes involving digestion, which is unrelated to reproduction. "Hormonal" refers to the system of hormones within the body, which could affect reproduction but does not specifically relate to the organs themselves. "Endocrinal" relates to the endocrine system—the glands that produce hormones—but again, it doesn’t directly reference the reproductive organs. Thus, "genital" is the most accurate descriptor for something pertaining specifically to reproductive organs.
