reproductive cycle
Generation-to-generation pattern
The reproductive cycle is the recurring sequence of biological events that enable an organism to produce offspring.
In humans and many mammals, this refers specifically to the menstrual or estrous cycle, during which hormonal changes prepare the body for potential pregnancy.
The term also encompasses broader patterns of fertility, mating, gestation, and birth that repeat throughout an organism's reproductive years.
Understanding the reproductive cycle is essential for both achieving and preventing pregnancy.
