1- The female reproductive system is formed by internal and
external organs. Although each organ has a specific function, all
these internal and external organs work together in a
synchronized way. Similar to the male reproductive system, its
function is to provide reproductivity of the human specie. In
addition, each month, in a cyclic manner, the organs produce and
sustain the female sex cells (ova), allow the transportation of the
egg to the uterus through the fallopian tube, provide an adequate
environment for fetal development after sperm fertilization as
well as the production of sex hormones. Anatomically, external
organs include vulva (labia majora, labia minora and clitoris) and
Bartholin’s glands (mucus secreting gland). It’s main role is to
enable sperm entry and to protect internal genital organs from
infection. Concerning the internal genital organs, we cite : two
ovaries, two fallopian tubes, one uterus, one cervix and one
vagina. At the beginning of the puberty, many follicles start to
grow and pass many stages (primordial follicle, primary follicle,
secondary follicle) until one follicle complete its maturation into a
Graffian follicle. This follicle contains an ovum. At ovulation, the
ovum is released and captured by the fallopian tube waiting for
fertilization. Fallopian tubes are the site of fertilization. In case of
fecundation, the egg travel the uterus and implant to develop
into pregnancy. If left unfertilized, the egg disintegrates and the
endometrium shed blood during a phase called menses.
2- The menstrual cycle is divided into two phases : the follicular or
proliferative phase and the luteal or secretory phase. The average
duration of each cycle is 28 days : 14 days for phase 1 and 14 days
for phase 2 separated by the ovulation at the 14
th
day. The
endocrine system plays a primordial role in controlling the
changes that occur at the level of the ovaries as well as the uterus
during both phases. The hypothalamus secretes a hormone called
gonadotrophin-releasing hormone (Gnrh). Gnrh stimulates the
