Sleepless nights, regular feeds, endless crying…Taking care of a
new-born baby can be a stressfully challenging time for any new mother.
Therefore, any woman could be forgiven for losing her sex drive in
the short-term whilst trying to battle a constant feeling tiredness on
top of feeling worried about still being appealing in the eyes of their
partner following post-pregnancy weight gain.
However and perhaps surprisingly, it is
not just mothers who have their libido impacted during the initial
stages of parenthood, with a new study suggesting that fathers are also
quite prone to losing their sex drive.
Researchers at Notre Dame University conducted the largest study of
its kind, analysing how the biology of 400 new fathers in the
Philippines altered following the arrival of their children.
Lead researcher Dr Lee Gettler, found that the men participating in
the study experienced a decrease of testosterone by about a third within
the first year after the birth of their child. In addition, hands-on
dads who spend at least three hours each day with their child typically
see a further decline of an estimated 20%.
Those behind the study claim “the sensitising effect” is created by
both the psychological and cultural impulse to protect a new-born baby
and would have a similar result on adoptive fathers; making them more
caring and less of an aggressive nature.
Past studies have demonstrated evidence that suggests men with high
levels of testosterone tend to have less sympathy in general and less
urgency to react when a baby is crying.
What the findings mean for new mums is perhaps a lesser risk of their
partner straying after the birth of their child, and women should have
less concern about upsetting him if she does not want to have sex often
in the initial first year. Women are simply programmed to prioritise
taking care of their children, with sex drive put on the backburner so
to speak.
“If you think about fathers in other mammalian species, they don’t
really help taking care of the children,” commented Dr Gettler.
“So it seems that natural selection has stepped up men’s hormone system to respond to the needs of their offspring.”
