6.6.3 Annotate a graph showing hormone levels in the menstrual cycle, illustrating the relationship between changes in hormone levels and ovulation, menstruation and thickening of the endometrium We begin with the hormone FSH (Follicle Stimulating hormone). 1) FSH increasing causing the ripening of the Graafian follicles and stimulating estrogen production (an example of positive feedback). 2) Increases in estrogen levels cause the repair of the endometrium and stimulate LH (Luteinizing hormone) production -- this is another example of positive feedback. 3) A peak in LH levels cause ovulation (the release of the ovum from the ovary to the oviduct) and the subsequent development of the corpus luteum. The corpus luteum is a temporary endocrine structure formed after the release of the ovum from the graafian follicles. Its role is to secrete progesterone and therefore levels of progesterone increase. 4) Increasing levels of progesterone maintain the endometrium in preparation for fertilization. a. If fertilization does occur the corpus luteum continues to secrete progesterone and the endometrium lining is maintained. b. If fertilization does not occur, the corpus luteum disintegrates, therefore decreasing progesterone levels. This means the endometrium is no longer maintained and so menstruation (the loss of the endometrium) takes place. c. Since there is a negative feedback relationship between progesterone and FSH, decreasing levels of progesterone result in increasing levels of FSH and this brings us back to the beginning of the cycle where we started from.

All rights reserved. Understanding the menstrual cycle. The menstrual cycle is a term used to describe monthly events that occur within a woman's body in preparation for the possibility of pregnancy. Each month, an egg is released from an ovary in a process called ovulation. At the same time, the lining of the uterus thickens, ready for pregnancy. If fertilization does not take place, the lining of the uterus is shed in menstrual bleeding and the cycle starts over. An ovary contains hundreds of thousands of primary oocytes - immature eggs, or ova. Each of these is enclosed in a structure called a follicle, and at this stage -- a primordial follicle. The menstrual cycle is under control of hormones secreted by the pituitary gland and the ovaries. The pituitary itself is under control of the hypothalamus. The hypothalamus produces a hormone called the gonadotropin-releasing hormone or GnRH. GnRH stimulates the anterior lobe of the pituitary to secrete follicle-stimulating hormone (FSH). FSH travels in the bloodstream to the ovaries and stimulates a group of follicles to grow. These primordial follicles develop into primary follicles and then secondary follicles. These produce a hormone named estrogen which acts to stimulate the growth of the endometrium -- the inner lining of the uterus. The secondary follicles compete with each other and only one of them will survive and become a mature follicle, the rest atrophy and die. The increasing level of estrogen also acts on the hypothalamus and the anterior pituitary to increase the level of GnRH and induce the production of another hormone -- luteinizing hormone (LH). A surge in LH secretion triggers ovulation - the release of the egg from the follicle and the ovary. The egg is then swept up by the fimbriae (FIM-bree-ee) and taken into the uterine tube. Fertilization by a spermatozoon, when it occurs, usually takes place in the ampulla, the widest section of the fallopian tube. The fertilized egg immediately begins the process of development while travelling toward the uterus. After 6 days it becomes a blastocyst and is implanted into the endometrium of the uterus. Meanwhile, the left-over of the ruptured follicle has become a corpus luteum which secretes progesterone. Progesterone further stimulates uterine development making it a nutritious bed for the embryo in the event of pregnancy. In the absence of pregnancy, the corpus luteum atrophies and progesterone level falls. This leads to the breakdown of the endometrium, menstruation begins and the cycle starts over.

Hello there! My name is Kora Kostiew and I made this video to bring more attention to an epidemic that thousands of girls face every year. This video discusses different causes to why girls injure their knees so much more frequently and more severely when compared to males. I also touch on research I am undertaking to hopefully find another cause that would lead to more knowledge and hopefully, in the future, a solution to girls' knee injuries. I felt that this problem needed to be discussed because these injuries have such a big impact on a girl's life. I would know since I have had a total of eight knee surgeries plus a knee transplant, which unfortunately ended my gymnastics career. Hopefully this prevalent problem can be solved soon with more research and I hope this video teaches people more about this issue. Thanks so much!

Watch more How to Get Pregnant videos: http://www.howcast.com/videos/218015-How-to-Know-When-Youre-Ovulating Step 1: Decide on a method Understand what's happening. Each month, an ovary releases an egg -- this process is called ovulation and is accompanied by physical symptoms such as changes in body temperature, cervical mucus, and cervical firmness. Experts recommend tracking at least two symptoms. Tip Many factors, including illness, stress, and certain medications, can influence ovulation. For guidance, consult a doctor. Step 2: Track your basal body temperature Before you get out of bed in the morning, take your basal body, or resting, temperature for five minutes. Use a thermometer that shows tenths of degrees, and use the same thermometer every day. On your calendar, note the temperature to the nearest tenth. Tip Ask your health-care provider for a fertility chart. Step 3: Examine your cervical mucus Check for cervical mucus every morning before bathing or urinating. Use clean fingers or a piece of toilet paper and swipe inside the opening of the vagina. On your calendar, note whether you have no mucus, cloudy or yellow mucus that is sticky, or mucus that is clear and stretchy. Step 4: Check for changes in your cervix Check for changes in the position and feel of your cervix. Use two clean fingers and gently reach back into your vagina until you can feel the cervix. On your calendar, note whether the cervix is easy or difficult to reach. Also note whether it feels firm, like your nose, or soft, like your lips. Step 5: Track your symptoms for at least two cycles Track your symptoms every day for at least two full menstrual cycles. The first day of menstrual flow is considered day one of your cycle. Tip You can also buy an over-the-counter ovulation predictor kit, which tests urine for certain hormones. Step 6: Monitor your temperature Look at the pattern of your basal body temperature. Your body temperature rises at least one-half degree after ovulation, and remains high until the end of your cycle. Step 7: Analyze your cervical symptoms Look at how your cervix changes. Cervical mucus becomes thicker before ovulation, and ovulation has most likely occurred when mucus is slippery and resembles egg whites. The cervix becomes softer and more difficult to reach as ovulation approaches. Step 8: Look for a pattern Look for patterns on your calendar or fertility chart. If your cervical mucus becomes clear on the same day your temperature goes up, you’ve most likely ovulated. Familiarize yourself with your body’s pattern, and you can anticipate future cycles and take charge of your fertility. Did You Know? A baby girl is born with over one million egg cells. During her lifetime, about 400 of them will develop into eggs and be released during ovulation.

Most women do not get excited about the monthly visit from “Aunt Flo.” In fact, most wish they did not have it and many actually take medication to stop it! What this tells me is how very little women know about their monthly cycle. The monthly menstrual cycle is a magnificently orchestrated event designed for the purpose of new life. Within a woman’ s 24-36 day cycle there are many fluctuations within the hormonal patterns that occur. Fluctuations in hormones can present symptoms such as tender breast, lower abdominal cramping, light spotting, hunger, lack of concentration, depression, bloating and anxiety. Understanding hormonal fluctuations can help in identifying and making sense of how you can feel so good one day and so awful the next!

If you’ve done everything you can and you still aren’t getting the yields you want, try some of these tips to boost your garden’s health and increase the amount of fruit your trees and bushes produce. 1.Go with Dwarfs. If you don’t want to wait several years to get fruit from your garden, consider planting dwarf varieties of your favorite trees. Dwarfs don’t grow as tall or as wide as a full-size tree so they begin to bear fruit within the first 2-3 years. These smaller trees also don’t require as much space, making them perfect for gardeners who want to grow their own fruit but don’t have a lot of land. 2.Prune as Needed. Fruit-trees ideally need to be trained in their first few years of growth into the shape you want them to maintain throughout their productive lives. Pruning should be done at the end of winter, before the tree comes out of dormancy. 3.Root-Suckers and Water-Sprouts. it is important to recognize that not all growth is good-growth. The production of flowers and fruit require a huge investment of nutrients and energy from your plants so you want to be certain that these resources aren’t being wasted where they aren’t needed. Root-suckers and water sprouts are two such wastes. New shoots that grow from the rootstock of a grafted fruit tree are known as root-suckers. These growths often look like a new plant that has taken root at the base of the existing parent. On the other hand, Water-sprouts are vertical shoots that grow straight-up from the established limbs of trees. While these growths aren’t nearly as undesirable as root-suckers, they can still be a waste of nutrients if they aren’t properly controlled. 4.Encourage Pollination Among your native plants, make sure something is blooming each season. Beneficial animals like bees, hummingbirds, butterflies, and bats are a few of the top-pollinators. For this reason, it is important to keep your garden hospitable for wildlife. Avoid overuse of pesticides which can kill beneficial-insects. 5.Know Your Soil. Plants are a lot like people in that different varieties and species have different tastes. It is important to know what balance of nutrients and trace minerals is best for each plant. Soil-pH can also play a big part in maximizing fruit yields. If you aren’t sure what kind of soil you have, it’s always better to test samples from around your trees and shrubs. Once you know what’s missing, you can amend the soil to boost future fruit-production. 6.Harvest Everything. This is perhaps the easiest advice to follow when it comes to growing successful fruit trees. Still, it bears mentioning. Unharvested fruit left-on the branch at the end of the season actually signals to the tree or bush that it made too much that-year. During the next growing season, the plant will actually produce less as a result. So make sure to pick-all of the fruit that your garden grows and let your plants know that you just can’t get enough!

I had this question the other day after reading or hearing something. I dug into what information I could find online, and figured there were other ladies out there with the same curiosity. While there was less out there on this topic than I was expecting I got my question answered. I got a bit of flack in my last video about chemicals. Apparently I shouldn't just say "chemicals" because some may be confused due to the fact everything is made from chemicals. So, I just want to start by saying that the chemicals I'm talking about are those that are being put into things that are causing harm, such as those that are endocrine disruptors, messing with not only the female reproductive system, but the male reproductive system as well. We wonder why so many girls and women have messed up menstrual cycles, and I think what's in our environment has a lot to do with it. I'm sure almost everyone has heard the term "endocrine disruptor", but who's taken the time to look into it? I'm just now taking the time. Let's learn together!

Symptoms of Having Baby Boy in 8th Month of Pregnancy | Baby Boy Symptoms During Pregnancy. How to get an intelligent baby: http://bit.ly/2ETLwu4 Indications of Having Baby Boy in eighth Month of Pregnancy | Baby Boy Symptoms During Pregnancy. 1. Knock Shape: While gazing in the mirror endeavoring to decide whether you're conveying low or high, you'll additionally need to focus on the state of the knock. A knock's shape is said to be everywhere in case you're conveying a young lady. In case you're conveying a kid, will father be super glad, as well as you'll have even more a ball shape than a wide shape. 2. Morning Sickness Indicators: Morning disorder is loathsome. You may hurl, you'll despise eating waffles – which you adore – and all that you gobble appears to return straight up. The reality of the situation is that even science doesn't know why ladies experience the ill effects of morning disorder. Here are the"Symptoms of Having Baby Boy". In any case, there is an old story that numerous ladies swear functions admirably in infant expectation. The story goes a touch of something like this: Simple morning infection shows a kid. Horrible episodes of morning disorder shows a young lady. I don't think about you, yet I am seeing an unmistakable sign that somebody favors young men when they attempt and foresee sexual orientation. 3. Sustenance Cravings and Choices: Pregnancy is odd. Your hormones are off the graphs, and out of the blue you have yearnings for dessert and pickles. It sounds gross, and it is to the vast majority, yet it's something you want nearly as much as you do breathing – or eating pizza. Here are the"Symptoms of Having Baby Boy". In case you're having a young lady, it's said that you'll like: Sugar. Flavor. You know, frozen yogurt took after by a hot and zesty burrito. Young men, then again, are said to make a lady eat healthy sustenances. This is the burger and fries kind of dinners that you won't have the capacity to get enough of when pregnant.

In any case, there is an old story that the shade of your pee is an indicator of your infant's sexual orientation. The thought is that: Here are the"Symptoms of Having Baby Boy". Overcast, dull and light pee implies you're having a young lady. Dull, neon pee implies you're having a kid. I wouldn't put much believability into the pee shading test, however a few ladies swear that it functions admirably for them. It could likewise be that the pre-birth vitamins are causing the neon-like pee. 5. Fetal Heart Rate: One of the signs you are having a kid or young lady is said to be the fetal heart rate. There are indicators that can help you through this sign, yet it's fairly basic truly. It couldn't be any more obvious, you have to decide the accompanying first: The fetal pulse: On the off chance that the fetal pulse is 140+ every moment, talk has it that you'll be having a child young lady. Fetal heart rates that are slower have a tendency to demonstrate that you're having an infant kid. Here are the"Symptoms of Having Baby Boy".

Cause http://perimenopausalbleeding.mymenopauseonline.com/ The causes of menopause can be considered from complementary proximate (mechanistic) perspectives (how it happens) or from ultimate (adaptive evolutionary) perspectives (why it happens). The latter group are hypotheses only. Proximate perspective Natural or physiological menopause occurs as a part of a woman's normal aging process. It is the result of the eventual depletion of almost all of the oocytes and ovarian follicles in the ovaries. This causes an increase in circulating follicle stimulating hormone (FSH) and luteinizing hormone (LH) levels because there are a decreased number of oocytes and follicles responding to these hormones and producing estrogen. This decrease in the production of estrogen leads to the perimenopausal symptoms of hot flashes, insomnia and mood changes. Long term effects may include osteoporosis and vaginal atrophy. Evolutionary theories of menopause In contrast to males, females invest more in their gametes, making them a highly valuable resource. Selection should therefore in theory favour a quantity of ova that would be sufficient for the female lifespan. Over-investment is resourcefully wasteful and under-investment leads to reduced fitness. Human females, however, spend over one third of their lifespan in a post-reproductive phase. Possible evolutionary explanations for survival beyond reproductive maturation range from the non-adaptive to the adaptive. Non-adaptive hypotheses The high cost of female investment in offspring may lead to physiological deteriorations that amplify susceptibility to becoming infertile. This hypothesis suggests the reproductive lifespan in humans has been optimized, but it has proven more difficult in females and thus their reproductive span is shorter. If this hypothesis were true however, age at menopause should be negatively correlated with reproductive effort and the available data does not support this. A recent increase in female longevity due to improvements in the standard of living and social care has also been suggested. It is difficult for selection, however, to favour aid from offspring to parents and grandparents Irrespective of living standards, adaptive responses are limited by physiological mechanisms. In other words senescence is programmed and regulated by specific genes.

Menstrual cycle explained: includes hormone phases in a woman explained (of the female reproductive system). These phases include the ovarian phases: Follicular, Ovulation, and Luteal and the uterine phases: Menstrual, Proliferative, and Secretory. A typical menstrual cycle in a woman is 28 days. The follicular phase of the ovarian cycle is approximately 1-13 cycle days and occurs simultaneously as the menstrual and proliferative phase of the uterine cycle. The menstrual phase occurs cycle days 1-6, while the proliferative phase occurs cycle days 7-14. During the menstrual phase, the stratum functionalis layer of the endometrium is shed. This phase occurs during the follicular phase. During the follicular phase the hypothalamus is releasing gonadotropin releasing hormone (GnRH) which stimulates the anterior pituitary gland to release follicular-stimulating hormone (FSH) and luteinizing hormone (LH). FSH stimulates the follicles in the ovary to mature. One follicle will mature into what is called a Graafian follilce which will release a mature egg called an ovum. As the follicle matures it steadily releases estrogen which causes the uterus to rebuild the stratum functionalis layer of the endometrium (during the proliferative phase) for possible implantation of a fertilized ovum. Once the Graafian follicle is mature estrogen peaks to a point where it will cause a positive feedback loop to the anterior pituitary gland which will cause a massive amount of luteinzing hormone to be release (known as the LH surge). LH causes the wall of the graafian follicle to break down and helps release the egg. Luteinizing hormone also turns the follicle into the corpus luteum. 24-36 hours after the LH surge ovulation occurs. Ovulation tends to occur on cycle day 14. Next is the luteal and secretory phase which occurs simultaneously as well. During the luteal phase, the corpus luteum is formed which releases progesterone and estrogen. These hormones play a role in making the endometrium ready for possible implantation. If pregnancy does not occur the corpus luteum will die in 14 days and turn in the corpus albicans and progestrone and estrogen levels will drop. This will signal for the hypothalamus to release GnRH which cause the anterior pituitary gland to release FSH and LH causing the reproductive cycle to start all over again. If fertilization of the ovum occurs, the fertilized egg will release HcG. HcG will prevent the corpus luteum from dying so pregnancy can be maintained. Once the placenta is fully developed it will take over with the secretion of progesterone and estrogen (which will occurs around 8 weeks gestation) and then the corpus luteum will die.
