Life Cycle of Sperm and Egg Essay

When asked how did I get enceinte? It seems like a rhetorical question. Of t prohibitency many would say well you had sex Watson. That is a no brainer, merely in all told actuality that is not the extent of the answer. How do we become pregnant? What happens in order for that miracle we call vivification to be created?The egg develops during the first base sort of the Menstrual Cycle. This first phase is called the Pro careerrative Phase. This phase begins at the end of your menstruation and last about 9 to 10 geezerhood during the mediocre 28-day cycle. The ovaries accordingly prep atomic number 18 for the ovulation within a phase called the preovulatory phase or the follicular phase. At this time there are low levels of estrogen and progesterone in the womanhoods rootage stream. A tell by Spencer A. Rathus, Jeffrey S. Nevid, and Lois Fichner-Rathus (2011) explains that the hypothalamus senses a low level of estrogen in the blood it accordingly increases secretion of Gn-RH, which in turn triggers the pituitary gland to exhaust a follicle-stimulating hormone (follicle-stimulating hormone).Thus after this occurs the FSH stimulates follicles to mature and then proceeds to create estrogen. In a normal situation lonesome(prenominal) one follicle willing endeavour true maturity in the days proceeding to ovulation. This then leads to maturity of the graafian follicle. As it matures like any bud child that blossoms and grow out of their clothes, this specific follicle starts to move toward the surface of the ovary and then eventually release itself after rupturing. During the rupturing mathematical operation this follicle releases a mature egg. afterward the egg is released the endometrium in the uterus starts to thicken due to the about of estrogen. Glands will eventually develop and these glands will help to feed any conceptus that may possibly exist. A thin cervical mucus is affected by the estrogen as well which will as well as furnish for nourishment for the sperm, increasing the chances of the sperms survival rate.The second phase of the cycle is the ovulatory phase, which involves the process in accordance the mature follicle egg being released. There is a misconception that the egg is released into the fallopian tube when in all actuality it is released near the tube itself. This phase begins with the estrogen levels peak.The third phase f the cycle is called the postuvulary phase or the secretory phase. Another name for this phase is the Luteal Phase, which derives from the name of the ruptured follicle (head teacher Luteum). Due to the influence the LH has on the Corpus Luteum the levels of estrogen are increasing as well as the levels of progesterone. Just like in the second phase when you reach this phase and the levels peak once once again and keeping in mind the egg has remained in the ovary. Within a normal 28-day cycle this tends to occur on either the 20 or 21st day. Hormones at this time cause the gla nds to release nutrients that will pass on for any fertilized ovum that may become implanted in the womans uterine wall. Picture a spider and its web and youve got the skillful of this phase. If the egg does not implant then the production of LH and FSH stops.The fourth and last phase occurs when the decrease of estrogen and progestone levels are no longer supporting the uterine lining. This cycle is also seen as the fountain and the end because the cycle not only end but also begins again. Most women would wish the cycle would not repeat itself but alas someone had a sense of humor when they thought of ways to take a shit things uncomfortable with a woman at least once a week for a few days.Just like everything else in life when God made man and women he made maturement easier on men. This is why I would assume that God must be a male. Even though the woman has four stages in order to reach the maturation of eggs a mans sperm development is a little more basic and no bleedin g necessary. The development of the sperm also has many stages and these stages take up to 72 days for the testes to develop a mature sperm. It seems everything must be mature comely to make any journey in life including eggs and sperm.Its like sending your kids off to college once they have passed all the phases of life and have graduated to the last step. In the beginning the sperm is called spermatocytes which pack 46 chromosomes which of course would be the famous letters x and y. each spermatocyte then divides or divorces and splits it assets in half and when divided it is then called a spermatid. Each spermatid at that time will house 23 chromosomes half will have x and half will have y. at once the sperm matures it is then called a spermatozoa, which have a head, a conic midsection, and a tail.Just like anything the core that is the mid section fork up the energy for the swimming power or for the tail to swim cover version and forth. For fertilization to occur 23 chromo somes from the fathers sperm satisfy a secret location and hook up (since there was no courting involved) with the 23 chromosomes from the mothers ovum. This of course would make up the 46. I wonder if this is what they meant when they said it takes two to tango.With all that is going on inside our bodies there is also so much that we already deal such as the testicles are like a storage container for sperm and house all the little fellas waiting for a raise to begin. For a woman it is more of a hid and seek game. Finding the egg that is disposed to our walls and locking all doors waiting to see if any sperm fucking pick the lock.We never take the time out to see all that we truly are and before having the obstacle course begin in our bodies it is good to know what exactly is going on and how these things truly do occur.
