Reproductive Process in Women
Organ reproduction with the condition of normal or good , and the cycle of menstruation are regularly every month is a sign of major fertility in women .
Organ reproductive women generally are internal. The vagina is one of them . Channel between the sections outside , called the vulva, with part inside , called the cervix or the mouth of the uterus . Rahim is an organ of the body that is full of muscles sized and shaped like pieces of pear. In here where cell eggs fertilized sperm cells and then become a place of embryo development , which then evolves into a fetus.
Rahim include a layer rich in nutrients which is called the endometrium. Tuba fallopian extends from the top of the uterus up to the part back to the ovary, where the presence of two bags of small which contain cells of eggs . A woman healthy and have a cycle of menstruation that is irregular , have cell eggs as many as 400,000 pieces and will undergo approximately 400 times the ovulation throughout the period of fertility , before menopause.
Besides memprodusi cell eggs mature in each cycle of menstruation , the ovaries also produce hormones women are called estrogen and progesterone. Every month, only one cell egg , which mature in the follicles in the ovaries. In the middle of the cycle , the egg is released from the follicle in a process called ovulation and will then be captured in the fallopian tube .
Part of the most outdoor and the last of the tube is more has the size that is wide and has a tip shaped like fingers, which are called fimbria, in which the cells of eggs will be waiting to be fertilized by cell sperm . Cells eggs then walk toward to bottom of tube fallopian heading into the uterus .
The menstrual cycle shows the process of maturity and release of the egg , and preparation of the uterus to receive and mature the embryo . Some cycles require about about 28 to 32 days and is divided into several phases :
- Follicular – Day to 1 until day to 13.
In the first cycle , menstrual in began in the womb with a release coating of the cycle before . The pituitary gland, which is located at the base of the brain, releases two kinds of hormones namely follicle-stimulating hormone (FSH) and lethinizing hormone (LH), which will stimulate the ovaries which will trigger follicular growth . Growth follicle produces the hormone estrogen , in which case this will change the uterus become slippery at the time of ovulation and is ready to accept the arrival of cell sperm .
- Ovulatory – about a day to 14, depending on the length of the cycle .
Phase is characterized by increased hormone LH which resulted in follicles shed until then cell eggs are released into the ovary. Fimbria from the fallopian tubes sweep the ovaries and carry the egg into the fallopian tubes .
- Luteal – day to 15 until about day to 28.
Luteal phase begins after ovulation . The follicles that produce cell eggs become wet , called the corpus luteum, producing the hormones estrogen and progesterone that is needed to finalize and provide nutrients to the cells of eggs that have been fertilized can be embedded and grow .
When cell egg meet with cells of sperm in the fallopian fallopian , occurs forming the conception of the cells of eggs that have been fertilized which then will move towards the uterus with the help of hair small that stick , which will sweep the cells of eggs that .
When have entered into the uterus , the embryo will be implanted in the uterus up to 6 days after ovulation . Furthermore embryo will produce a hormone which is called chorionic gonadotropin ( hCG ) that is useful to provide a signal or a sign of the body that pregnancy has occurred . Corpus luteum can feel the pregnancy and will continue to produce progesterone and prepare the uterus for pregnancy .
If pregnancy does not occur , the cell eggs will pass past the womb and while the corpus luteum will take place on a day to 26. Layers uterus then will fall and be shed in a few days and the period of menstruation the next begins .
Reproductive Process in Men
The reproductive system in men consists of 2 types , namely external and internal. Sperm are produced in parts of the body of the man who called the testes. Sperm are produced and then going through the channels of the epididymis to deposit and receive nutrients .
Sperm mature will move to the vas deferens, which is a place that connects the epididymis with the line producer of cement. Shaped in the form of two bags gland which is located at the back of the gall bladder that will connect each channel of the vas deferens leading to the urethra. Channel -producing sperm have resulted in approximately 90% liquid in each ejaculation .
When ejaculation occurs , the liquid cement will be formed as a gel which then will be liquefied in a 5 to 30 minutes . Sperm can survive to live for 48 to 72 hours in line reproductive female to fertilize cell egg . It ‘s become a cause of why the relationship sexually during the time of ovulation had a possibility greatest for the conception or pregnancy .
Factors that determine capable or not cells of sperm a man can fertilize cell egg :
- The amount of cement produced , generally amounts to 1.5 to 5 ml.
- Sperm density , normally amounts to 15 million per ml.
- The shape of the sperm ,> 4% shaped normally.
- Motion sperm ,> 40% move quickly , meeting , pointing to the front .
Although the number of sperm rated very important , the motion of sperm becomes more important in determining the ability of sperm to fertilize cell egg . A man is still said to be fertile if he has high – quality sperm cells even though the numbers are only a few .
Three (3) types of hormones that affect sperm growth :
- Follicle Stimulating Hormone (FSH)
- Luteinising Hormone (LH)
FSH and LH dalah hormones are the same that is required to regulate the function of reproduction in women . But the man both hormones it has two sole responsibility of the different . FSH is responsible for stimulating sperm production in the testes, while LH helps stimulate testosterone production . Testosterone is a hormone that encourages sexual desire and produces sperm.
