FERTILIZATION

,FERTILISATION AND DEVELOPMENT OF THE
FERTILISED OVUM


 Fertilization takes place when the sperm meets
the ovum in the fallopian tube.

 After ovulation, the ovum passes into the
fallopian tube and is moved along by the cilia and
the peristaltic muscular contraction of the tube.



 At this time the cervix produces alkaline mucus
that attracts the spermatozoa.

, When intercourse takes place many spermatozoa
(about 300 million) are deposited in the upper
vagina.

 Those that reach the light cervical mucus survive
and propel themselves towards the fallopian
tubes while the rest are destroyed by the acid
medium of the vagina.

 Many sperm will reach the fallopian tube where
they meet the ovum.

,  During this journey the sperm mature and are
capable of producing an enzyme known as
hyaluronidase, which will help penetration into
the ovum.

 Only one sperm will enter the ovum. After the
sperm goes into the ovum, the membrane is
sealed to prevent other sperm from entering.
