Background: Ovarian cysts are among the diseases which cause reproductive failure and economic losses in dairy herds. High yelding dairy cattles are suseptable to reproductive failure caused by ovarian cysts, as a result of their exposure to stressful coditions during lactation. OBJECTIVES: This study aimed to monitor metabolic profile tests in dairy cows with ovarian cysts in comparison with c...

BACKGROUND: Ovarian antibodies as detected by indirect immunofluorescence have been used to detect ovarian autoimmunity, but to our knowledge the rate of false positive findings using this method has never been reported. METHODS: Here we examine whether a commercially available ovarian antibody test system, using cynomologous monkey ovary, might be useful in the diagnosis of autoimmune prematur...

BACKGROUND There is a lack of evidence regarding current screening practices for incipient ovarian failure in young women following gonadotoxic therapy and the most appropriate form of estrogen replacement. This study examined the (i) prevalence and management of ovarian failure and (ii) quality-of-life implications of early menopause (EM). METHODS A medical case note audit for 288 women with...

OBJECTIVE To prospectively estimate the risk for earlier ovarian failure among women undergoing hysterectomy with ovarian preservation, as compared with women of similar age without hysterectomy. METHODS A prospective cohort study was conducted among women aged 30 to 47 years undergoing hysterectomy without bilateral oophorectomy (n=406) and women with intact uteri (n=465). Blood samples and ...

The mammalian zona pellucida is an extracellular matrix that occurs in growing oocytes, ovulated eggs and pre-implantation embryos, and is known to be involved in several important events during ovarian folliculogenesis and fertilization. Since the zona pellucida is formed at an early stage of oocyte growth, circulating antibodies against zona pellucida may impair ovarian function. In this arti...

OBJECTIVES The objectives were to determine the time course for ovarian failure in rats caused by 4-vinylcyclohexene diepoxide (VCD) and develop a model for ovarian cancer in which ovarian neoplasms were chemically induced in an animal that was follicle depleted, but retained residual ovarian tissue. METHODS Initially, female Fisher 344 rats were treated with VCD (to induce ovarian failure) o...

OBJECTIVE To determine the frequency and causes of preterm ovarian failure (menopause before 40 years of age) and early menopause (menopause between 40 and 45 years). DESIGN Cross sectional study. SETTING Menopause clinics in Italy. POPULATION Women attending menopause clinics in Italy. METHODS Between 1997 and 1999 we conducted a large cross sectional study on the characteristics of wo...
