WHAT IS REQUIRED FOR BUILDING GROWTH?
Normal number of men and in particular sperm production,
Clear and adequate function of sperm ducts,
The fact that the tubes that transmit the egg in the female are open,
Sexual relations in the days of ovulation,
Meeting of sperm and egg and fertilization,
The uterine function suitable for the placement of the fertilized egg,
The fertilized egg is settled in the womb and gets embryo and fetus (fetus)
The birth of the baby who has completed his development.
SPERM PRODUCTION
Male reproductive cells are produced in sperm testes. Unlike women, production begins in the age of the present and continues until the end of life. Sperm production is continuous in men, although ovulation occurs once a month in the women's period and one (rarely) several ovum cells occur.
At birth there are the main sperm cells (spermatogonium) that will produce sperm in the male eggs. These cells wait quietly until puberty. In puberty, the secretion of hormone (FSH, LH) secretion begins to divide in the main sperm cells in the egg. The resulting new cells also become sperm through various stages of cleavage, development and differentiation.
Approximately 50-200 thousand sperm are produced per minute in the testes. The sperm that form in the channels of the testes enter the canal system called the epididymis. The sperm, which continue to mature here, gain the ability to move independently when they reach the tail of my epididymis. It takes about 70 days to complete the development of a sperm cell and become mature.
The sperm consists of 5-7 micron length, 3-4 micron width, pear shaped head, 2-3 micron length neck and 40-45 micron length tail.
Spermin Out
When sexual arousal occurs, sperm cells begin to accumulate in the secretions of semen vesicles and prostate, in the posterior urinary tract and in the draining ducts. For accumulation, the upper bladder side of the urinary tract in the prostate and the lower side of the prostate are closed by the sphincter system (constrictive mechanism). The fluid that accumulates on this count does not escape from the urinary tract and into the womb. The accumulating fluid is called semen.
When sexual arousal reaches its peak, an ejaculation reflex begins. While the inner sphincter of the bladder is closed, the outer sphincter is opened. At the same time, the muscles in the urinary tract and in the draining ducts contract rapidly and rhythmically. With these contractions, semen is ejected out of the urine hole with a few gushes in a gushing style.
EGG CELL PRODUCTION
The tissues on both sides of the waistbone of the fetus on the mother's stomach begin to differentiate into ovaries on the fetal chromosomes and females. At the 6th week of gestation in the differentiating ovary, the egg cells of the ooconia become obvious. By the 20th week the main egg cells multiply by dividing. Then, with 46 chromosomes (genes), these cells enter the cleavage stage, which reduces the number of chromosomes. This division between 7th and 9th months of pregnancy is not complete. Those cells that remain in the cleavage stage receive the name oocyte. Oocytes, surrounded by a cell layer, start to wait silently in the ovary. The number of these is fixed and does not change later. In other words, the female egg has a certain number of reproductive cells, unlike the erectile.
Oocytes that remain unchanged in the ovary from birth to adulthood will develop into mature egg cells after puberty. However, 99% of them disappear for various reasons, only about 1% develop into egg cells.
EGGS (OVULASION)
On the 14th day of the female period, the amount of LH increases suddenly from the hormones secreted from the brain pituitary (hormone-releasing region in the middle of the brain) region. Subsequently, the mature follicle cracks and releases the egg cell. This is called ovulation.
In the ovary, hormones called estrogen and progesterone are produced during the development of the egg cell. The estrogen in the first period before laying and the hormone progesterone in the second period after laying allow the tissues in the uterus to become suitable for the nesting of the fertilized egg. Otherwise the fertilized egg will not be nestled in the womb and will be low.
