How long before conception should I improve diet?

Sperm take 70 to 90 days to mature, so any dietary change needs at least 3 months to show in semen analysis results.

Are antioxidant supplements better than mango?

Trials use supplements for consistency, but the British Fertility Society favours dietary sources first. Supplements have a small benefit; over-supplementation (especially zinc) can backfire.

Does this apply to female fertility too?

Yes, broadly. Antioxidant intake is associated with better oocyte quality and IVF outcomes in women. The mango benefit is non-sex-specific.

Mango and male fertility

Why antioxidants matter for sperm

Sperm are uniquely vulnerable to oxidative damage because their membranes are unusually rich in polyunsaturated fatty acids. Oxidative stress (from smoking, obesity, infection, varicocele) damages DNA and reduces motility, a recognised contributor to male-factor infertility.

Dietary antioxidants, particularly vitamin C, vitamin E, zinc and selenium, neutralise reactive oxygen species in seminal plasma. A Cochrane review (Smits et al., 2019) of 61 trials found antioxidant supplementation modestly improved live birth rates in subfertile couples.

Vitamin C and DNA integrity

Trials on vitamin C specifically (200 to 1,000mg/day) have shown 30 to 50% reductions in sperm DNA fragmentation. The mechanism is direct ROS quenching in seminal fluid, where ascorbate concentrations are 10× those in blood plasma.

200mg/day is achievable from diet, two Chaunsa mangoes, a kiwi and a couple of strawberries hit it without supplements.

Beta-carotene and sperm count

A Harvard cohort (Eskenazi et al., 2005) found men in the top quintile of beta-carotene intake had 14% higher sperm motility than the bottom quintile. Pakistani Chaunsa is one of the densest dietary beta-carotene sources available in the UK.

The effect is modest and observational, so don't expect mango alone to move the needle. The right framing is: cumulative antioxidant intake across the diet matters, and mango contributes more than most fruits.

Pragmatic advice

If you and your partner are trying to conceive, dietary antioxidants are one of the cheapest, lowest-risk interventions. The other big factors, stop smoking, lose excess weight, manage stress, treat varicocele if present, matter more individually.

A daily mango isn't a fertility cure. It's a sensible part of a Mediterranean-style diet that the IVF clinical literature consistently associates with better outcomes.
