Nuts for Your Nuts!

An interesting 14 week long study in Spain used more than 100 young men (https://www.theguardian.com/society/2018/jul/04/want-stronger-healthier-sperm-eat-your-nuts). Half the subjects were given 60g of mixed nuts (almonds, hazelnuts and walnuts) to eat each day but the others ate normally without the 'nut snack'.At the end of the study, only the 'nut-snackers' showed a 16% increase in sperm count, along with some evidence of increased sperm mobility and potency. The authors suggested that the nut's content of  polyunsaturated oils, vitamins C and E, along with trace elements like zinc and cadmium might account for these changes. It would be interesting to know if the groups had similar numbers of folk in long-term sexual relationships and comparable (except for the nuts) dietary intakes. Given declining sperm counts throughout the western world, however, this dietary supplement might prove helpful.
