Answer
Testosterone, Estrogen
Explanation
The question pertains to two significant processes in human reproduction: sperm production in males and the initiation of the menstrual cycle in females. These processes coincide with the onset of puberty, during which the body undergoes hormonal changes. In males, testosterone, an androgen, is the primary hormone that increases during puberty. This hormone is critical for the growth of male reproductive tissues, secondary sexual characteristics, and sperm production. Therefore, it's the hormone that completes the first blank. Regarding females, an increase in the production of estrogen commences the developmental stages of puberty including the bolstered growth of the breasts, wider hips, and starting of the menstrual cycle. As the question specifically concerns the commencement of the menstrual cycle, the appropriate hormone for this situation is estrogen.
