The prevailing trend
suggests a perception
of declining fertility and
increasing infertility.
While there are arguments both
in favor of and
against this notion,
the available evidence is
not definitively conclusive.
A clear consensus
regarding the decline
in fertility or the rise
in infertility is lacking.

Infertility is typically defined
as the inability to
achieve conception
after a year of consistent
unprotected sexual activity.
It's worth noting that
multiple definitions
of infertility exist,
including clinical, demographic,
and epidemiological
perspectives.
Recently, there has been scrutiny
surrounding the applicability
of this one year time
frame to all age groups.
Additionally, this definition
does not precisely outline
what constitutes regular
unprotected intercourse.
The term regular
remains ambiguous.
Is it once, weekly,
monthly, or daily?
This vagueness can
significantly impact
the probability of
achieving pregnancy.
Various definitions
of infertility exist,
each with its limitations.

Referencing a study
conducted in the UK,
the distribution of
infertility causes
is depicted in this slide.
Male factors contribute
to 30% of cases,
while female factors
account for 45%.
Within female factors,
tubal issues contribute to 20%
and ovulatory disorders to 25%.
Unexplained infertility
contributes 25%.
