What is the primary function of the male reproductive system?

The primary function of the male reproductive system is to transmit genetic material to offspring. This is achieved through the production of sperm, which are the male gametes responsible for fertilizing the female egg. The male reproductive system is designed to create, store, and deliver sperm during sexual reproduction, thus playing a crucial role in the process of passing genetic information from one generation to the next.

While hormones are produced in the male reproductive system, particularly testosterone, they play a supportive role in regulating functions such as libido, spermatogenesis, and secondary sexual characteristics. However, the primary objective remains genetic transmission.

Other options do not pertain to the reproductive system's role. Regulating blood sugar levels and providing energy for bodily functions are functions of the endocrine and digestive systems, not the reproductive system. The focus of the male reproductive system is explicitly centered on reproduction and the continuation of genetic lineage.
