- Moderate exercise helps testosterone and sperm quality - but overdoing it works against you
- A balanced, antioxidant-rich diet is genuinely linked to better sperm quality
- We used a traditional one too: dates in milk (dried dates, also called kharak) - a few studies do exist on dates and testosterone/sperm health
- This is preparation for both partners, not just the pregnant one
Preconception prep isn't only the pregnant partner's job. There's a real, researched half of this that belongs to him - and it's worth doing in parallel with everything else in this section.
Move, but don't overdo it
Regular moderate exercise is linked to healthier testosterone levels and better sperm motility and shape. The sweet spot in the research is something like walking or jogging 30 minutes, 3 to 6 times a week - not a daily marathon-training block. Interestingly, very intense or extreme exercise (long-distance running, high-altitude trekking) is linked to worse sperm health, not better. Moderate and consistent beats extreme.
Eat like it matters, because it does
A balanced diet - genuinely rich in fruit and vegetables, antioxidants (vitamin C, vitamin E, zinc, selenium), omega-3s, vitamin D, and folate - is associated with better semen quality. It's the same "eat the colourful plate" advice you'd give anyone, except here there's a fertility reason attached to it too. Weight matters alongside diet - carrying excess weight is linked to lower sperm counts, so this is diet quality and a healthy weight together, not one or the other.
What we actually did: dates in milk
Alongside the exercise and the diet, I made him dates in milk - dried dates (kharak), warmed in milk. A traditional preparation, and one with real research behind it worth knowing about: a few studies do exist linking date consumption to increases in testosterone and improvements in sperm count and motility, and animal studies show similar results. Human research is still smaller in scale than the diet-and-exercise evidence above, but it's a genuine, ongoing area of study, not just folklore - which is exactly why it earned a place in our own routine.
