Ovary

Either by wind or a pollinator, pollen grains are carried to the sticky stigma of the ovary and sperm burrow their way down to the ovules. One sperm will fertilize the ova, becoming the zygote, and the other will fuse with the central cell and become the triploid endosperm nucleus. The zygote further develops into the embryo that is surrounded by the endosperm that is encased in a diploid seed coat. The ovary will then swell into the fruiting…

Primarily in this phase, the hormone Gonadotropin – releasing hormone (GNRH) is produced by the hypothalamus, stimulating the pituitary gland which in turn secretes the Follicle – stimulating hormone (FSH). FSH then travels through the blood to the ovaries, where it stimulates follicle growth around the oocyte. (Diagram 3). The developing follicle secretes oestrogen which then activates the generation of the endometrium, the increased levels of oestrogen cause the pituitary gland to secrete the…

Polycystic ovary syndrome is known as a hormonal problem, which is believed to be involved with genetic and environmental factors for its development. Women with PCOS normal have High levels of androgens. These are sometimes called male hormones, though females also make them and or many small cysts (fluid-filled sacs) in their ovaries. A main underlying problem with PCOS is a hormonal imbalance. The cause of PCOS is also…

production is poorly coordinated during the normal menstrual period, inappropriate bleeding and shedding of the endometrium also can occur. During menopause (between 48-55 years old), reduced amount of estrogen and progesterone is produced by the ovaries. Atrophy of the pelvic organs occurs in aging women because of diminished estrogen production after…

(Trigonella foenum-graecum), is used widely in numerous parts of the world as herb, food, spice, and traditional medicine. Different preprations of fenugreek have been reported as an effective remedy against polycystic ovarian disease. Polycystic ovary syndrome (PCOS) is one of the most widespread hormonal disorders among women of reproductive age causing irregular menstrual cycles, histurism, miscarriage and infertility. The study will be conducted to determine physicochemical characteristics…

Ovarian cancer is when cells begin to uncontrollably reproduce in the ovaries, and may spread to other parts of the body. It ranks number five in cancer deaths among women and accounts for more deaths than any other cancer of the reproductive systems of women. It starts in the ovaries and can spread to the rest of the body, giving the woman's lifetime chance of dying from the disease 1 in 100. This cancer mainly develops in older women- about half of the women who are diagnosed are over 63 years…

syndrome (Ellison & Meliker, 2011). This can result after utilizing hormone injections to stimulate the growth of ova in the ovaries. There are no preset doses of hormone that are used; instead, amounts of hormones used vary for every woman (Ellison & Meliker, 2011). An excess of the hormone can cause the ovaries to become painful and swollen. Complications can extend beyond the ovaries and can cause events such as heart attacks, strokes, renal failure, and potentially uterine cancer (Dondorp &…

gonadotropin or hMG (Repronex®, Pergonal®): This medicine is often used for women who don't ovulate due to problems with their pituitary gland. hMG acts directly on the ovaries to stimulate ovulation. It is an injected medicine. • Follicle-stimulating hormone or FSH (Gonal-F®, Follistim®): FSH works much like hMG. It causes the ovaries to begin the process of ovulation. These medicines are usually injected. • Gonadotropin-releasing hormone (Gn-RH) analogs: These medicines are often used for…
