Unlike other primates, human females do not have a distinct estrus period, and they are potentially able to mate and conceive at any time during their menstrual cycle. This is known as concealed ovulation. Other primates typically have visible signs of estrus such as changes in color or swelling of genitalia, indicating a peak in fertility.
