Hormones fertility

Options are medical hormonal treatments and/or surgery. Surgical treatment by laparoscopic ablation of endometriotic lesions plus adhesiolysis may improve fertility. Hormonal treatments should not be used for endometriosis in women with fertility problems as they tend to lead to ovarian suppression. Laparoscopic ablation of endometrial deposits may relieve pain in some women. Radical surgery (e.g. total abdominal hysterectomy, salpingo-oophorectomy or both) is reserved for women who have completed their family and in whom other treatments have failed. It is usually curative although... 

Antibody-based immunological tests were in vogue before the development of monoclonal antibodies. For example, earlier pregnancy tests were based on the detection of fertility hormones by using polyclonal antisera. To a large extent, this and other such tests now use monoclonal antibodies, and occupy a large segment of the commercial immunoassay market (Campbell, 1991 Scott and Fleischman, 1991 Hoffman... 

Hormone storage and release. Fora woman to be fertile, hormones must be stored and available for release at the precise time of need. Chemicals that block the storage sites or prevent their release once stored interfere with hormone availability. 

There are a many reports that evaluate the performance of the nonliquid reagent systems however, owing to proprietary constraints, there are relatively few articles that describe the actual preparation or detail the characteristics of these analytical devices. This veil of secrecy is particularly true of the Drichem (82) and Konica nonliquid reagent systems information on these systems is confined almost exclusively to the patent literature. Very few clinical or performance evaluations have been reported. Therefore, these systems will not be dealt with in this overview. The OPUS (83) and the Stratus II (84) Immunoassay Systems are also nonliquid reagent systems that deal with the immunoassays of therapeutic drugs, fertility hormones, thyroid function, and other metabolites. The Stratus II can also be used to measure CK-MB as the protein rather than the enzyme. An excellent review by Chan (85) describes the hardware and performance of the OPUS, Stratus, and other such systems. 

Xenobiotic induced disruption of female fertility follows essentially the same pattern as that of the male and can be caused by changes in pituitary-hypothalamic function, primary disruption of ovarian structure or hormone secretion, or changes in the rate of hormone deactivation. In addition, there may be changes in the synthesis of estrogen induced production of the yolk protein by the liver (vitellogenesis), which in turn can lead to failure to lay down sufficient yolk in the developing oocytes. Vitellogenesis provides a valuable biomarker for endocrine dysfunction in both sexes,but is more properly considered as part of the liver function. 

Hormonal contraceptives belong to the most widely prescribed and most efficacious drugs that have a profound impact on western societies since their inauguration in the 1960s. In women, oral hormonal contraceptives are used to prevent fertilization or implantation in cases of unplanned pregnancies. Apart from these primary objectives, there are significant additional medical benefits contributing to a substantial improvement of reproductive health in women. 

The health effects of phytoestrogens fertility, development and hormonal effects... 

Phytoestrogens were first associated with adverse effects on mammalian development and fertility from observations of animals consuming phytoestrogen-rich plants. Ewes feeding on Australian clover developed abnormal plasma concentrations of endogenous hormones with subsequent loss of fertility (Bennett etal.,l 946 Moersch et al., 1967 Obst and Seamark, 1975). 

There has been some speculation that estrogenic compounds may adversely affect the fertility of men by reducing testosterone levels and sperm counts (Atanassova et al, 2000). To date, however, the limited information available suggests that consumption of phytoestrogens does not affect reproductive hormones or semen quality (Nagata, 2000 Nagata et al., 2001 Mitchell et...
