Biological rhythms in reproductive processes

Biological rhythms play an important role in the regulation of many different physiological systems, including the reproductive system. The 24-hour clock system plays a role in regulating the production, release, synthesis and action of reproductive hormones and in the timing of critical events in the ovarian cycle. Research into the importance of biological rhythms on human reproduction is just beginning, future work is likely to reveal new and unexpected ways in which these rhythms affect human reproduction.
