Quizplus · Accepted Answer

Environmental cues typically affect reproduction by directly affecting the hormonal control mechanisms that regulate reproductive processes. For example, changes in day length (photoperiod) can trigger changes in the secretion of reproductive hormones, such as luteinizing hormone and follicle-stimulating hormone, which can then initiate ovulation or spermatogenesis. Other environmental cues, such as temperature, food availability, or social cues, can also affect hormone secretion and therefore influence the timing of reproduction.
