The fertilization
The cycle of a woman begins the first day of rules
The cycle is the number of days between the first day of rules and the day before the start of the following rules
Ovulation occurs roughly between the 12th and 16th days before the start of the following rules, period or female sex hormones prepare the body to release an egg
During each cycle, one of the ovaries of the woman produces an egg, then released at the time of ovulation in the fallopian tube, where it can be fertilized by a sperm
During a sexual relationship, the testes produce millions of sperm to be deposited at the bottom of the vagina. A small portion of them crossed the cervix and then head to the tubes
The fertilization resulting from the penetration of a single sperm into the ovum and occurs at the wrong
The embryo formed joined the uterus after a few days and then it becomes established in the lining: the so-called implantation of the embryo
The sex hormones produced by the femmeLes sex hormones play a vital role in the smooth running of the menstrual cycle and fertilization
The female hormones are secreted in 3 stages:
The hypothalamus, located above the pituitary secretes GnRH
The pituitary gland at the base of the brain secretes the gonadotropins, LH and FSH
The ovaries produce estrogen and progesterone
These three floors communicate with each other: GnRH modulating the secretion of gonadotrophins, which themselves regulate the secretion of sex hormones by the ovaries.
The estrogen in turn hinder the secretion of GnRH, LH and FSH
The LH and FSH allow ovulation. The LH triggers the process of ovulation, but a balance between FSH and LH is necessary to get mature, which will release an egg during ovulation.
