Male cycle

[Thomas_Belgium]

Many years ago I read men have cycles. Past years I tried to figure out my cycle, for example to figure out when I could lower my daily dose tadalafil, but I couldn't find a pattern. Did you figer out your cycle?

These are the only kinds of men’s cycles I can think of:

I tried tracking mine for a while but it just felt random. For me, things like diet and gym schedule seem to have a much bigger impact than any internal cycle I could find.

Wouldn't surprise me if La Luna caused perceptible shifts in male hormones. Nor would it surprise me if the shifts were perceptible only to women.

If cycle is referring to phases of being horny (for lack of better word) versus not, I’m curious. Some weeks it seems like it occupies my mind nearly constantly and I do something about it daily. Other weeks it’s the last thing on my mind and I wonder if I’ll ever get the urge again. Which of course I do! No rhyme or reason I can figure out but I do know these cycles each last longer than they used to.

Yes, I'm indeed talking about being horny indeed.

Thanks, I guess people don’t have much interest in this one way or another! I’ve just noticed longer cycles of each type (“on” and “off”) the older I get.

I don’t believe men have a hormonal cycle comparable to the female menstrual cycle. There isn’t a predictable 28-day or similar pattern in male hormones that most men experience consistently enough to track or use for adjusting something like a daily tadalafil dose.

Men’s primary sex hormone, testosterone, follows a daily circadian rhythm. It typically peaks in the early morning, within a couple of hours of waking, and gradually declines throughout the day, reaching its lowest levels in the evening.

Tadalafil is a PDE5 inhibitor, works by relaxing blood vessels to improve blood flow, and its effectiveness isn’t directly tied to daily or monthly testosterone fluctuations.

In my own experience, fluctuations in libido tend to be more related to factors like stress levels, sleep quality and exercise rather than any kind of hormonal cycle.

My cycle seems to be about three days horny, three days not horny. If I can figure out my cycle I can lower my dose tadalafil on the days when I don't feel horny.

That makes sense.  That would explain why the only time I'm not thinking about sex is when I'm asleep!

When I'm asleep I seem to be thinking about sex because I have many erotic dreams.
