Male Fertility: The Complete Science-Based Guide to Sperm Health and Optimisation for Conception Success

Of all the factors that influence human fertility, age is the one that is least modifiable and most misunderstood. Conversations about age and fertility are too often dominated by either excessive alarm — suggesting that fertility effectively ends at 35 — or wishful minimisation, asserting that modern medicine can overcome virtually any age-related challenge. The scientific reality is more nuanced and, for most people, more hopeful than either extreme suggests. This guide examines the relat...

Sperm can survive up to five days in the female reproductive tract, while the egg remains viable for only 12-24 hours. A landmark study in the New England Journal of Medicine found conception probability rises from 10% five days before ovulation to 33% on the two days before ovulation. How to Accurately Track Ovulation Ovulation Predict...

A diagnosis requires at ...
