Wohl M, Gorwood P. As mentioned earlier, it was reported that the sperm parameters do not change until males reach the age of 34 years [ 40 ]. Also, younger fathers are likely to come from disadvantaged background, which can contribute to poor postnatal care [ ]. It is proposed that further research should be conducted to demystify the mechanisms involved.
