Hop­ing for a baby? Why au­tumn is the best time to get started

Daily Mail - - EDEN CONFIDENTIAL - From Vic­to­ria Allen Science Cor­re­spon­dent in Den­ver

FOR cou­ples think­ing about try­ing for a baby, now might be a good time to start.

A study has found sperm qual­ity is at its best in au­tumn and spring.

These ‘in-be­tween sea­sons’ pro­vide re­lief from the ex­cesses of Christ­mas overeat­ing and al­co­holic sum­mer bar­be­cues, which can harm men’s fer­til­ity.

They are also cooler than sum­mer, when warmer tem­per­a­tures can re­duce sperm counts. Doc­tors ex­am­ined sperm sam­ples from 29,000 men from 2001 to 2018 to find trends in se­men qual­ity over the year.

The num­ber of motile sperm – which swim best – was high­est in spring, and the most nor­mally-shaped sperm – best for con­ceiv­ing – were in au­tumn.

Study lead au­thor Dr Taraneh Nazem, of Ic­ahn School of Medicine in New York, said: ‘There’s some­thing about these in­be­tween sea­sons.

‘Maybe au­tumn and spring are a lit­tle bit more bal­anced, and tem­per­a­tures are milder.’

The re­search, pre­sented at the Amer­i­can So­ci­ety for Re­pro­duc­tive Medicine in Den­ver, Colorado, echoes the results of a 2014 study by Sh­effield Uni­ver­sity which also found sperm qual­ity was worst in sum­mer.
