The term "male period" is colloquially used to refer to blood found in urine or feces, which is often the result of parasites or an infection. However, cisgender men do not have menstrual periods, as they are not born with a uterus and do not have a uterine lining that will be released from the body as blood through the vagina. Men do experience hormonal fluctuations, and some claim that these fluctuations may cause symptoms that mimic the symptoms of premenstrual syndrome (PMS), including depression, fatigue, and mood swings. These hormonal fluctuations can have some pretty notable side effects, especially with mood and irritability, and are sometimes referred to as "man periods" or Irritable Male Syndrome (IMS) . However, IMS is not recognized as a medical diagnosis, and there is no medical evidence of it. Mens testosterone levels fluctuate throughout the day and decrease with age, which can cause symptoms similar to PMS. Although men may experience symptoms similar to the female menstrual cycle, including tiredness, cramps, increased sensitivity, and cravings, they will not bleed. In conclusion, while men may experience hormonal fluctuations and symptoms similar to PMS, they do not have menstrual periods.
