Reproductive physiology is the study of the biological processes and functions involved in reproduction, including the development of gametes (sperm and egg cells), fertilization, pregnancy, and childbirth. This research area often focuses on understanding the hormonal and physiological mechanisms that regulate reproductive processes in both males and females, as well as investigating factors that can affect fertility and reproductive health. Researchers in this field may also study the impact of environmental factors, genetics, and lifestyle choices on reproductive function, as well as develop new reproductive technologies and treatments for fertility issues. Overall, reproductive physiology aims to expand our understanding of the mechanisms underlying reproduction and to improve reproductive health outcomes for both humans and animals.
