5Reduced Sex Drive
You should notice any considerable changes in the sex drive. As an effect of premenstrual syndrome, the level of libido in your body would be reduced. Noradrenaline or norepinephrine is an important hormone in the brain that regulates emotions, arousal, as well as sleep. A drop in this substance would lead to a loss of your sexual interest. When ovulation begins, the levels of estrogen reduce. This would also decrease the amount of norepinephrine since estrogen would competitively prevent some enzymes from activating the hormone. Make sure to seek immediate medical treatments to prevent this condition from affecting your relationships. [5]
