Harun Yahya

The menstrual period is when the unfertilised egg is expelled from
the body. Since fertilisation has not taken place, the walls of the previ-
ously readied womb contract and the egg is expelled with the breaking
of tiny blood vessels. Following that, the body will then begin prepara-
tions to repeat the whole process all over again.
All of these stages are repeated in all women over a specific period.
Every month, new egg cells form, the same hormones are secreted-again
and again at the same times. Thus the female body is prepared as if it

will be fertilised. However, in the final stage, the absence or presence of
the sperm changes the nature of the preparations in the body.
During the period in question, the changes in the empty space in
the womb can only be identified by an anatomical or gynaecological
examination. Yet these changes, only recently identified by scientists,
are miraculously indicated in Surat ar-Ra‘d:
Allah knows what every female bears and
every shrinking of the womb and every
swelling. Everything has its measure with
Him. (Qur'an, 13:8)
At the beginning of the menstrual
period, the mucous on the walls of the
womb (the endometrium layer) is 0.5
mm (0.02 inch) thick. Under the effect
of hormones secreted by the egg, this
layer grows and reaches a thickness of
5-6 mm (0.2 inch). This layer is then
discarded in the absence of fertilisation. As
we see from the above verse, this monthly
increase and reduction in the walls of the
womb is indicated in the Qur'an.
