Reproductive organs with normal or good condition, and a regular menstrual cycle each month is the primary sign of fertility in women.
The female reproductive organs are generally is internal. The Vagina is one of them. The channel between the outside of the, called the vulva, with the inside, called the cervix or cervical. The uterus is a muscular organ that is full-sized and shaped like muscular fruit pear. Here is where the fertilized egg cell and sperm cell then becomes a growing embryo, which later evolved into the fetus.
Womb of furnished nutrient rich lining called the endometrium. Fallopian tubes extending from the uterus to the ovaries toward the rear of the, where there are two small bags containing the ovum. A woman healthy and had regular menstrual cycles, have the ovum as much 400.000 fruit and will have approximately 400 ovulation times throughout his exuberance, before menopause.
In addition to the ripe egg cells memprodusi in every menstrual cycle, the ovaries also produce the female hormone estrogen and progesterone called. Each month is only one ovum, a mature follicle in the ovary in. In the middle of the cycle, the egg is released from the follicle cells in a process called ovulation and then will be captured in the fallopian tubes.
The very last of the tuba and the outside is more have wider size and having the tip shaped like fingers, called fimbrae, where the egg cells will wait for the fertilized by sperm cells. The egg then travels to the fallopian tubes leading down into the uterus.
Menstrual cycle shows the process of maturity and release of the egg, and preparation of the uterus to receive and ripen the embryo. Some cycle requires about 28 until 32 days and is divided into several phases:
When the egg meets the sperm cells inside the fallopian tubes, going on the formation of the conception of the ovum that has been fertilized that will then move towards the uterus with the help of a small hair stick, that will sweep the ovum.
When entered into the uterus, the embryo would be implanted in the womb until 6 the day after ovulation. Next the Embryo would produce a hormone called chorionic Gonadotrophin (hCG) useful for signal or sign to the body that pregnancy has occurred. Corpus luteum of pregnancy can and will continue to produce progesterone and prepares the uterus for pregnancy.
If pregnancy does not occur, the egg will pass through the uterus and in the meantime a corpus luteum will take place on the 26. Lining of the uterus will then fall and decays in a few days and the next menstrual period begins.
The reproductive system in men is composed of 2 type, the external and internal. Sperm are produced in the body of the man who named the testes. The resulting sperm then going through the epididymis ducts for storage and nutrition.
Mature sperm will move towards the vas deferens, that is a place that connects epididymis with cement producers with channels. The shape is in the form of two bags of glands that are located on the back of the bladder that will connect each channel of the vas deferens to the urethra. This sperm-producing channels generate about 90% the fluid in each ejaculation.
When ejaculation occurs, the liquid cement will make up as gel which will then be melted within 5 up to 30 minutes. Sperm can survive for 48 until 72 hours in the female reproductive tract to fertilize an ovum. This is the cause why sexual intercourse during ovulation has the largest possibility for occurrence of conception or pregnancy.
The factors that determine whether or not sperm cells capable of a man can fertilise the egg :
Although the number of sperm is assessed is critical, sperm motion becomes more important in determining the ability of sperm to fertilize an egg. A man remains said to be infertile when has sperm cells of high quality although there was only a little.
Three (3) kinds of hormones that affect growth of sperm :
FSH and LH are the same hormones needed to regulate reproductive function in women. But on the second man this hormone has two different responsibilities. Responsible for FSH to stimulate sperm production in testicles, While the LH stimulates testosterone production help. Testosterone is a hormone that encourages sexual desire and produce sperm.
