41. E-Doc: Medicine Info For Urofollitrophin (FSH)
A high level of gonadotrophins indicating primary ovarian failure. Primary ovarianfailure should be excluded by determination of serum FSH and LH.
http://www.edoc.co.za/medilink/actives/1072.html

Medicine Info:
Active Ingredients
Urofollitrophin (FSH)
Mechanism:
  • Follicle stimulating hormone is a trophic hormone, stimulating the growth of follicles in the ovary.
Indications:
  • For the induction of ovulation in anovulatory women, especially in cases where Luteinising hormone is raised eg. polycystic ovarian syndrome.
Contra-Indications:
  • Pregnancy.
  • Patients with intracranial lesions, adrenal or thyroid disorders, ovarian cyst enlargements.
  • Presence of any cause of infertility other than anovulation as stated in the indications.
  • A high level of gonadotrophins indicating primary ovarian failure.
  • Patients with abnormal vaginal bleedng of undetermined origin.
Dosage:
  • Management of overdose:
    • Symptoms: See side-effects.
    • Rx : Withdrawl of medicine. Symptomatic and supportive.
  • Dose:
  • See Metrodin* (trade name)
Side-Effects:
  • FSH when given with LH may cause sensitivity reactions and dose related ovarian hyperstimulation varying from mild ovarian enlargement and abnormal discomfort to severe hyperstimulation with ovarian rupture and intraperitoneal haemorrhage. There may be ascites, pleural effusion, oliguria, hypotension, arterial thrombo-embolism. Swelling of pre-existing pituitory tumours leading to visual field defects may occur during pregnancy in women treated for infertility.
  • There is a risk of multiple births.

UpToDate performs a continuous review of over 290 journals and other resources. Updates are added as important new information is published. The literature review for UpToDate version 11.1 is current through December 2002; this topic was last changed on September 17, 2001. Amenorrhea (absence of menses) can be a transient, intermittent, or permanent condition resulting from dysfunction of the hypothalamus, pituitary, ovaries, uterus, or vagina ( show table 1 and show table 2 ). It is often classified as either primary (absence of menarche by age 16) or secondary (absence of menses for more than three cycle intervals or six months in women who were previously menstruating). The menstrual cycle is susceptible to outside influences; thus, missing a single menstrual period is rarely important. In contrast, prolonged amenorrhea might be the earliest sign of a decline in general health or signal an underlying condition, such as a pituitary tumor. The causes and diagnosis of primary amenorrhea, as well as a brief summary of treatment options, are reviewed here. The evaluation of secondary amenorrhea is discussed separately. (

http://www.rxmed.com/b.main/b2.pharmaceutical/b2.1.monographs/CPS- Monographs/CP
HUMEGON® Organon Human Gonadotropin Human Gonadotropins Action And Clinical Pharmacology: Humegon (human gonadotropin) is a purified preparation of gonadotropins extracted from the urine of post menopausal and pregnant women. It contains follicle-stimulating hormone (FSH) and luteinizing hormone (LH), both of which are necessary for the normal gamete maturation (follicle ripening in the female and spermatogenesis in the male) and for gonadal steroid production. Unlike menotropins, human gonadotropin is standardized with hCG. Human gonadotropin is used to stimulate these processes in selected cases of disturbed gonadal function. It is generally used in combination with a gonadotropin with LH activity, such as human chorionic gonadotropin (hCG). The combined treatment may be either sequential (in the case of ovulation induction) or concomitant (in the case of Leydig cell stimulation). tag_IndicationsIndications
Indications And Clinical Uses: Women: Human gonadotropin and human chorionic gonadotropin (hCG) given sequentially are indicated for the induction of ovulation and pregnancy in females infertile due to anovulation where the cause of anovulation is functional and not due to primary ovarian failure.
Men: Human gonadotropin and concomitant hCG is indicated for the stimulation of spermatogenesis in males with primary or secondary hypogonadotropic hypogonadism.

Description
Follitropin alfa (fol-li-TROE-pin AL-fa) is a hormone identical to follicle-stimulating hormone (FSH) produced by the pituitary gland. FSH helps to develop eggs in the ovaries. Follitropin alfa is used as a fertility medicine to develop eggs in women who have not been able to become pregnant because of problems in ovulation. Also, many women wanting to become pregnant will use this medicine while enrolled in a fertility program (assisted reproductive technology [ART]) that uses procedures such as in vitro fertilization (IVF) or embryo transfer (ET). Follitropin alfa may be used with other medicines for these purposes. Follitropin alfa is also used as a fertility medicine to help men with low sperm counts produce more sperms. Treatment with human chorionic gonadotropin should come before treatment with follitropin alfa. This pretreatment elevates the amount of testosterone to the correct level. Treatment with human chorionic gonadotropin should continue as long as follitropin alfa is being used. Some patients may be treated with another hormone called gonadotropin-releasing hormone agonist (GnRHa) before starting treatment with follitropin alfa. GnRHa reduces the amount of FSH released from the pituitary gland. This is done so that the doctor can replace their FSH with follitropin alfa in the proper amounts each day to achieve fertility.

  • The definition of secondary amenorrhea is the absence of menses for at least 3 months in a women who has previously had her menarche. The prevalence in the general population is 2-5%. Hyperprolactinemia amenorrhea is one cause of secondary amenorrhea. Drugs that cause hyperprolactinemia include estrogens, androgens, anxiolytics, narcotics, methyldopa, reserpine, amphetamines, and H2 blockers. Prolactin should be measured in the morning in a fasting state. A normal level is 20-25 ug/L. A relatively common cause of amenorrhea in young women is an acquired form of hypogonadotrophic amenorrhea due to emotional distress, nutritional deficiency, or athletic activity. The female athletic triad is defined as the combined conditions of disordered eating, amenorrhea, and osteoporosis that occurs in female athletes. Physiologic causes of secondary amenorrhea include pregnancy and menopause.

    HOME Introduction What is it? Causes ... Buy the book!
    Fact Sheet: Premature Ovarian Failure (POF) A Brief Look at POF As has been said elswhere on the site, premature ovarian failure (POF) is a condition that used to be called "premature menopause." It's marked by post-menopausal hormone levels and no periods (amenorrhea) ocurring before the age of 40. While it's similar to menopause, it's not strictly menopause. There are several key differences. One of the most important differences is that many women with POF can and do still ovulate from time to time and can even get pregnant. (According to statistics, this occurs to roughly 8 to 10% of women with POF.) This is because POF doesn't necessarily mean lack of viable follicles. Yes, some women with POF do have early depletion of follicles (which is then, in effect, menopause). But others nearly half according to some experts actually still have follicles. The problem in this case is a "disconnect" between hormones and ovarian function or an autoimmune problem. Premature ovarian failure as with many conditions develops over time. Prior to full-blown POF (i.e. no periods for at least 4-6 months and post-menopausal hormone levels), you move through different stages through what's now called "primary ovarian insufficiency" (POI)

    We propose that the presence of anti-zona pellucida antibodies can be detected in human serum. By screening serum obtained from donors with a) POF, b) subfertility, and c) neither of those conditions we intend to determine if their is a correlation between the presence of aZPA and POF in women.
    Introduction:
    Little is known about the causes of Premature Ovarian Failure (POF) in women. This disorder is defined as the loss of ovarian function before the age of forty. It is clinically characterized by secondary amenorrhea and endocrinologically by a hypergonadotropic, hypoestrogenic state. Unfortunately, a definite etiological factor can not be determined for most cases (van Kasteren, 1999).
    Currently, the condition is divided into two classes: excessive depletion of follicles and follicles that are present but fail to function properly. It is also likely that different classes POF exist due to different causes or varying levels of the agents responsible for this disorder. It is possible that one of the major or contributing causes of POF dysfunction involves the autoimmune reaction against the oocyte and/or other components of the follicle. Such a primary relationship might follow an initial abnormal exposure of zona material to the immune system. Alternatively, in POF or other types of pathology, anti zona pellucida antibodies (aZP) might form as a secondary consequence of disease conditions (Shivers and Dunbar, 1977).

    http://www.drdaiter.com/47.html
    Premature Ovarian Failure Ovarian failure results when there are no eggs available for maturation. With ovarian failure the fertility prognosis is poor unless donor eggs are used. The FSH concentration (ideally with LH and estradiol concentrations) can confirm ovarian failure. In one study, women with gonadal (ovarian) failure and primary amenorrhea were consistently found to have no follicular activity on pathology reports (of the ovarian tissue) when the FSH concentration was greater than 40 IU/L. These data may not be entirely applicable to ovarian failure with secondary amenorrhea, but consistently elevated FSH concentrations (usually greater than 25 IU/L and certainly greater than 40 IU/L) with a coincident low estradiol concentration (to rule out a FSH producing pituitary tumor) and secondary amenorrhea strongly suggests ovarian failure.
    Menopause is the absence of menstruation due to the depletion of eggs capable of maturation. The average age of menopause in the USA is about 51-52 years old. Less than 1% of women have "menopause" when younger than 40 years old, so that when this occurs it is called "premature ovarian failure" or POF. There appear to be two main causes of this accelerated loss of eggs such that there is total depletion of maturation capable eggs at a very young age (POF). First, there may be a chromosomal abnormality in the X chromosome affecting the genes that regulate the rate of egg loss. Second, autoimmune disease that produces antibodies that can attack and destroy the ovaries is able to result in early ovarian failure.

    Presentation of the Woman With Premature Ovarian Failure
    The age at which POF occurs may depend upon the number of follicles initially present and the pace of follicular atresia. It may present as primary or secondary amenorrhea. Women with primary amenorrhea are more likely to have a genetic basis for the POF, having had a smaller complement of oocytes initially. About half of women with POF have a history of infrequent or irregular menses, while about one fourth stop menstruating suddenly. Often these women also have a recent history of infertility. Although those women with primary amenorrhea have no symptoms related to low estradiol levels, the majority of those with secondary amenorrhea typically present with the complaints of hot flashes, fatigue, and mood changes. Theses symptoms may start before the complete cessation of menses. Women with primary amenorrhea may present with signs of Turner's syndrome, while those with secondary amenorrhea usually have normal physical findings. At least one third of women with POF have ovarian follicles visible on ultrasound and many have estradiol levels over 50 pg/ml. Almost 20% may occasionally ovulate. A recent study showed no relationship between the risk of POF and age at menarche, cycle length, and oral contraceptive use. Parity was related to a decreased risk of POF and those women with POF were more likely to have a history of infertility.
