why corpus luteum degenerates when the ovum is unfertilised?
466567
it produces lots of estrogen and progesterone, which inhibit lutenizing hormone which, if left unchecked, would keep the corpus luteum large.  so the corpus luteum, indirectly kills itself.

A doctor told me once that orgasm can stimulate ovulation- thus causing a second period in a cycle. It never happened to me, but it could explain all those pregnancies that couldn't possibly happen!

Hey girl, I have had the same problem for the past eight years. My doctors tell me tha I have an hormone imbalance and this inhibits ovulation some months and ultimately affects my menstrual cycle.\n\nI was unable to get pregnant for some time until recently (my son is nine months).\n\nYou need to do tests to confirm whether or not this is so or if there are other problems. All the best!

A certain amount of free fluid in the pelvis, behind the uterus, is normal at certain points in your cycle; after ovulation, a small amount of fluid released with the egg collects behind the uterus and is eventually reabsorbed by the body. A larger amount of fluid may indicate a ruptured ovarian cyst. Pain is usually present in this instance, but most often resolves on its own within a few days. Infection is another possibility, but in this case symptoms such as pain and fever are often significant.

Women over 35 MAY have more difficulty conceiving and bearing a child.\n\nTwo reasons for this:\n\n1) A woman has as many eggs are she will ever have at birth. As she ages, her eggs do too, and their quality does decline with age. This means a higher risk of miscarriage, certain birth defects (like Down's syndrome), and also, if the egg released at ovulation  is of poor quality, a lower likihood it will implant and grow if it is fertilized (making it harder to get pregnant).\n\n2) As women approach menopause, they may ovulate less frequently, meaning fewer chances per year of getting pregnant. Also, changes in the hormonal workings of their reproductive organs could result in a lower quality egg, as the egg must be "ripened" and matured in the ovary before being released each menstural cycle.\n\nAll said, fertility is a very individual thing. Age may decrease the ease or liklihood of a woman getting pregnant, but it depends a lot upon the individual woman (and man) involved.

Here you go I hope this helps! And no Flying won't make it pop/rupture!\n\nBackground: Ovarian cysts and their complications can be present from the neonatal period to postmenopause. Most ovarian cysts occur in the childbearing years and are benign in nature. However, ovarian cysts can herald an underlying malignant process or, possibly, become a red herring, distracting the clinician from a more dangerous condition, such as ectopic pregnancy, ovarian torsion, or appendicitis.\n\n\nPathophysiology: Under the guidance of the hypothalamic-pituitary axis, the healthy ovary produces hormones that regulate follicular maturation and degeneration within the menstrual cycle. \n\nMultiple follicles are recruited during the proliferative phase of the menstrual cycle. However, only one follicle reaches maturity and produces estrogen. The follicular cyst transforms into a corpus luteum following ovulation and produces progesterone until the beginning of the next cycle. At that time, the follicle usually atrophies into the corpus albicans. \n\nFollicular dysgenesis occurs with hypothalamic-pituitary dysfunction or because of native anatomic defects in the reproductive system. When follicular development into a corpus luteum is arrested, a luteal ovarian cyst can result. \n\nTwo functional ovarian cysts may develop; follicular cysts (ie, graafian follicular cysts) occur in the first 2 weeks of the cycle, and corpus luteal cysts occur in the later half of the cycle. The rupture of the follicular cyst can lead to sharp severe unilateral pain of mittelschmerz (occurring mid-cycle), and it is experienced by approximately 25% of menstruating women. Similarly, failure of corpus luteum degeneration leads to a luteal cyst formation. These may become inflamed or spontaneously hemorrhage, producing symptoms during the later half of the menstrual cycle. \n\nCarcinomatous processes of the ovary, both primary and metastatic (eg, Krukenberg tumors), frequently are complicated by cystic degeneration. The formation of inclusions of the ovary's germinal epithelium may lead to cystic development. \n\nOvarian cysts can cause adnexal torsion, with a predilection to the right side. Cysts larger than 4 cm are more likely to cause torsion, but reports of such occurrences have been observed at 2 cm. Torsion more commonly occurs in a cystic ovary accompanied by a tumor, with benign processes outnumbering malignant ones. Benign dermoid cysts are the most common growth associated with torsion. Because torsion results from complete or partial twisting of the ovarian pedicle, an obvious sequela is ovarian necrosis. This sequence terminates with inflammation, possibly leading to infection, sepsis, and death. Increased incidences of ureteral injury, ovarian vessel thrombosis, and concomitant pulmonary emboli also have been reported. \n\nOvarian cysts are commonly complicated by hemorrhage. The right side appears preferred in hemorrhagic degeneration. It is postulated that the rigid rectosigmoid on the left provides cushioning from trauma and twisting. This may reduce torsion and hemorrhagic complications. The relatively lax ileocecal region on the right is not as efficient at such prevention as the left. \n\nIn patients with a hemorrhagic ovarian cyst, look for an ectopic pregnancy because the coexistence of both entities is increased. Putting the obvious complications aside, a hemorrhagic cyst in the course of pregnancy leads to a marked increase in the incidence of spontaneous abortions and warrants close obstetrical observance. \n\nThe timing of the menstrual cycle may help to differentiate the types of hemorrhagic cysts. Graafian follicle cysts occur in the initial 2-3 weeks of the cycle, whereas corpus luteal cysts occur in the final 1-2 weeks of the cycle. \n\nOvarian cysts also are associated with infertility and irregular menstrual bleeding. Finding a cyst in a woman of postmenopausal age should prompt an all out search for ovarian neoplasms. No functiona

From http://en.wikipedia.org/wiki/Menstrual_cycle\n\nOnly human beings and the great apes experience a true menstrual cycle. Most placental mammals experience estrus instead. The menstrual cycle is under the control of the reproductive hormone system and is necessary for reproduction. In women, menstrual cycles occur typically on a monthly basis between puberty and menopause.\n\nDuring the menstrual cycle, the sexually mature female body releases one egg (or occasionally two, which might result in dizygotic, or non-identical, twins) at the time of ovulation. The lining of the uterus, the endometrium, builds up in a synchronised fashion. After ovulation, this lining changes to prepare for potential implantation of the fertilized egg to establish a pregnancy. If fertilization and pregnancy do not ensue, the uterus sheds the lining and a new menstrual cycle begins. The process of the shedding of the lining is called menstruation. Menstruation manifests itself to the outer world in the form of the menses (also menstruum): essentially part of the endometrium and blood products that pass out of the body through the vagina. Although this is commonly referred to as blood, it differs in composition from venous blood.\n\nCommon usage refers to menstruation and menses as a period. This bleeding serves as a sign that a woman has not become pregnant. (However, this cannot be taken as certainty, as sometimes there is some bleeding in early pregnancy.) During the reproductive years, failure to menstruate may provide the first indication to a woman that she may have become pregnant. A woman might say that her "period is late" when an expected menstruation has not started and she might have become pregnant.\n\nMenstruation forms a normal part of a natural cyclic process occurring in healthy women between puberty and the end of the reproductive years. The onset of menstruation, known as menarche, occurs at an average age of 12, but can occur any time between the ages of 8 and 16.[1] However, the condition precocious puberty has caused menstruation to occur in girls as young as 8 months old. The last period, menopause, usually occurs between the ages of 45 and 55. Deviations from this pattern deserve medical attention. Amenorrhea refers to a prolonged absence of menses during the reproductive years of a woman for reasons other than pregnancy. For example, women with very low body fat, such as athletes, may cease to menstruate. The presence of menstruation does not prove that ovulation took place; women who do not ovulate may have menstrual cycles. Those anovulatory cycles tend to take place less regularly and show greater variation in cycle length. In addition, the absence of menstruation also does not prove that ovulation did not take place, because hormone disruptions in non-pregnant women can suppress bleeding on occasion.\n\nWomen show considerable variation in the lengths of their menstrual cycles, and the length of the menstrual cycle differs in different animals.\n\nWhile cycle length may vary, 28 days is generally taken as representative of the average ovulatory cycle in women. Convention uses the onset of menstrual bleeding to mark the beginning of the cycle, so the first day of bleeding is called "Cycle Day one".\n\nOne can divide the menstrual cycle into four phases:\n\nMenstruation\nEumenorrhea denotes normal, regular menstruation that lasts for a few days (usually 3 to 5 days, but anywhere from 2 to 7 days is considered normal.[2] The average blood loss during menstruation is 35 millilitres with 10-80 mL considered normal;[3] many women also notice shed endometrium lining that appears as tissue mixed with the blood. An enzyme called plasmin — contained in the endometrium — inhibits the blood from clotting. Because of this blood loss, women have higher dietary requirements for iron than do males to prevent iron deficiency. Many women experience uterine cramps, also referred to as dysmenorrhea, during this time

After having children the mucus discharge does thicken. The irregular bloody spotting with it probably means your system is a bit out of whack after having children and being off Depo. Talk to your OB/GYN and see if getting back on some kind of birth control will help regulate your periods again. If they continue to get worse though, they might consider a D&C or ablation. Stop using Depro though...it's now being related to bone disorders. Ask your dr. about the NuvaRing....it's easy to use and works very well. Regulated my periods immediately!

I already told you. That you could be pregnant because you were having unprotected sex. The bleeding that you experienced was due to your going off birth control and possibly due to your miscarriage. It was hormonal. It does not mean that you were not ovulating. Since you were taking birth control, it is going to throw off your cycle a little bit and your ovulation will be sporatic. It could happen anytime! \n\nWhen a woman is not taking birth control, typically she will ovulating half way through her cycle but, birth control supresses ovulation and some women ovulate irregularly even during their period! Since you went off birth control and were only on it for 2 weeks, you were not protected and could have ovulating the first day off the pill or a few days later when you started to bleed. The only time that it is safe to have sex while off active pills is if you took at least 21 active pills in a row. You did not. You may have ovulated. \n\nTake a pregnancy test  because you had unprotected sex and talk to your doctor about getting sterilised because you seem to need it.

the part of flower that gets converted to fruit on fusing with sperms from the pollen grains is the ovary... the ovules inside the ovary gets converted into seeds

the follicle of the ovary breaks and an egg emerges.  Little hairs extending off of the fallopian tubs guide the egg into the tubes.\n\nThe egg travels through the fallopian tubes floating on the current caused by the tiny hairs in the fallopian tubes.  The end of its journey is a gentle rest upon the nutrient walls of the uterus.

The female sexual cycle is a repeating process on average lasting for 28 days.\nIt's purpose is to;\n\n    * release a single mature ovum\n    * prepare the uterine endometrium for implantation\n\nThe cycle can be broken down into a number of phases...\n\nFollicular Phase (10-16 days)\nThe follicular phase corresponds to the proliferative phase of the endometrium.\n\n    * The pituitary gland, located in the middle of the base of the brain, releases two hormones, follicle-stimulating hormone (FSH) and luteinizing hormone (LH).\n    * These stimulate the ovary and cause follicular growth.\n    * It is during the follicular phase that a cohort of eggs are recruited and begin to develop and mature inside fluid-filled follicle within the ovary.\n    * As these eggs develop fewer and fewer progress until only one remains.\n      At about days 5-7 of cycle the dominant ovarian follicle emerges and vascularity doubles for this follicle.\n    * The developing follicle secretes the hormone estrogen.\n\nOvulatory Phase (36 hours)\n\n    * The ovulatory phase begins when the level of LH surges, causing the follicle to burst and the egg to be released from the ovary.\n    * The fimbria of the fallopian tube sweep over the ovary and wave the egg into the fallopian tube.\n    * There are changes in the cervical mucus, which becomes clear and thin and increases in quantity, helping sperm through the cervical canal.\n\nLuteal Phase (14 days)\nCorresponds to the secretory phase of the endometrium.\n\n    * During the luteal phase, the follicle that produced the egg becomes a functioning gland called the corpus luteum.\n    * The corpus luteum produces oestrogen which continues to promote the proliferative activity in the endometrium and progesterone which prepares the uterus with the thick lining needed for implantation.\n\nIf implantation does not occur then;\n\n    * The ovum passes through the uterus,\n    * The corpus luteum will cease to function on about Day 26 and regress,\n    * There will be a rapid fall in the secretion of estrogen and progesterone,\n    * The endometrium shrinks due to extracellular fluid loss,\n    * The endometrial blood flow decreases with cell death and destruction of blood vessels,\n    * The uterus will then break down and shed its lining,\n\nMenstruation (4 - 5 days)\nMenses\n\n    * The menstrual bleeding as the uterus sheds the endometrium from the previous cycle.\n    * Blood Loss: 20-80 ml (av. 35 ml).\n    * Demise of corpus luteum.\n    * Estrogen and Progesterone withdrawal.
