Are there any studies that look into the topic of sexual abstinence and the release of pheromones? I'm trying to gain an understanding of the NoFap movement and such from a scientific point of view. I did it once, got up to 60 days, and despite my behavior and personality being relatively the same as it always has been, at the time, women were flirting with me left and right. I cannot come to any other conclusion other than the possibility that pheromones are involved and almost like a sixth sense women can recognize when a man is fertile. Is this all currently pseudoscience and conjecture or is there any scientific basis to this theory?
