men don't have a monthly hormonal cycle to sync seeds to in the way seed cycling was designed for, since seed cycling is built around the rise and fall of oestrogen and progesterone across the menstrual cycle. that said, there's nothing stopping a man from eating a daily rotation of flax, pumpkin, sesame and sunflower seeds for general nutritional reasons.
why the "cycling" part doesn't apply
the whole premise of seed cycling is timing certain seeds to certain phases of a menstrual cycle, based on which hormones are more dominant at each stage. without a menstrual cycle, there isn't a follicular or luteal phase for the seeds to correspond to, so the phase-based logic simply doesn't have anything to attach to.
what the seeds still offer
- flaxseed and pumpkin seeds are a good source of fibre and healthy fats, including omega-3s
- pumpkin seeds and sunflower seeds both contain zinc, which supports several general body functions
- sesame seeds offer minerals like copper and calcium, plus healthy fats
so while a man eating these seeds daily won't be "seed cycling" in the technical sense, he'll still be getting a reasonable spread of fibre, healthy fats and micronutrients from doing so, which is a perfectly sensible reason to eat them even without the cycling framework.
if there's a specific reason a man is interested in seed cycling, for example wanting to support a partner's routine or reading about seeds and testosterone or fertility, it's worth looking into the evidence for that specific question directly, rather than assuming the cycling structure itself will apply, since the mechanism it's based on doesn't exist without a menstrual cycle.
