Infertility - a common problem Part 1 (Teacher: Michael)
Infertility is
Select
an
a
the
problem that affects something like one couple in every ten. Think about that. It is
Select
an
a
the
remarkable figure. One out of every ten couples can't have
Select
an
a
the
baby which they desperately want. There are said to be approximately 40 possible physical causes of infertility, although you could probably find more if you looked hard enough.
Among women,
Select
an
a
the
common problems are
Select
an
a
the
failure of ovulation and
Select
an
a
the
blockage of
Select
an
a
the
fallopian tubes (often caused by some previous infection). Among men (who are just likely to be
Select
an
a
the
cause of infertility as their partners),
Select
an
a
the
problems commonly include failure to produce spermatozoa in sufficient numbers, and
Select
an
a
the
failure to produce spermatozoa of good enough quality. Those disorders can themselves be traced back to other problems in many causes.
When
Select
an
a
the
woman fails to ovulate, for example,
Select
an
a
the
cause may be
Select
an
a
the
specific disorder such as endometriosis or
Select
an
a
the
general complaint such as
Select
an
a
the
sudden weight loss. When
Select
an
a
the
man doesn't produce enough sperm, or produces sperm of
Select
an
a
the
inferior quality,
Select
an
a
the
basic cause may be
Select
an
a
the
old infection, such as mumps, or
Select
an
a
the
accident. Of course, there can be mechanical causes for infertility.
