PURPOSE This cohort study was established to investigate the effects of unilateral and bilateral oophorectomy on the ageing processes in women. PARTICIPANTS We used the records-linkage system of the Rochester Epidemiology Project (REP, http://www.rochesterproject.org) to identify 570 women who underwent unilateral oophorectomy and 1653 women who underwent bilateral oophorectomy in Olmsted Cou...

BACKGROUND The evidence for a neuroprotective effect of estrogen in women remains controversial. OBJECTIVE We studied the long-term risk of parkinsonism and of cognitive impairment or dementia in women who underwent oophorectomy before menopause. METHODS We conducted a historical cohort study among all women residing in Olmsted County, Minn., USA, who underwent unilateral or bilateral oopho...

OBJECTIVE To describe a coelioscopic-assisted prefemoral oophorectomy technique for use in chelonians. DESIGN Descriptive report. ANIMALS 11 adult female turtles (6 red-eared sliders, 2 box turtles, 1 painted turtle, 1 four-eyed turtle, and 1 Chinese red-necked pond turtle). Five turtles required oophorectomy because of reproductive tract disease; the remaining 6 underwent elective oophorec...

Women experience a significant decline in circulating androgen concentrations after bilateral oophorectomy. Despite several limitations, studying women after oophorectomy remains a good model for investigating the effects of both androgen deficiency and androgen replacement. Current data show that most women experience satisfying sexual lives after hysterectomy and bilateral oophorectomy. This ...

OBJECTIVE To report long-term mortality after oophorectomy or ovarian conservation at the time of hysterectomy in subgroups of women based on age at the time of surgery, use of estrogen therapy, presence of risk factors for coronary heart disease, and length of follow-up. METHODS This was a prospective cohort study of 30,117 Nurses' Health Study participants undergoing hysterectomy for benign...

STUDY QUESTION Is unilateral oophorectomy associated with age at menopause? SUMMARY ANSWER Women who had undergone unilateral oophorectomy entered menopause 1 year earlier than women with two ovaries intact. WHAT IS ALREADY KNOWN There is substantial variation in age at natural menopause. Unilateral oophorectomy implies a significant reduction of the ovarian follicular reserve. Thus, one mi...

BACKGROUND Bilateral oophorectomy is commonly performed at the time of hysterectomy for benign disease. Indications for oophorectomy vary, but in most cases relatively little high-quality information is available to inform the surgeon or patient regarding the relative risks and benefits of ovarian conservation or removal. This review will address the common clinical situations when oophorectomy...

OBJECTIVE To study the association between bilateral oophorectomy and the rate of accumulation of multimorbidity. PATIENTS AND METHODS In this historical cohort study, the Rochester Epidemiology Project records-linkage system was used to identify all premenopausal women who underwent bilateral oophorectomy before age 50 years between January 1, 1988, and December 31, 2007, in Olmsted County, ...

1. The effects of a low calcium diet and of oophorectomy, separately and together, on cortical and trabecular bone mass, have been examined in mature female rats. 2. Calcium deprivation caused a significant decrease of weight, cortical cross-sectional area and ratio of cortical to total area in the femur, it significantly reduced the volume of trabecular bone and increased the percentage of ost...

This study was undertaken to determine the incidence of subsequent oophorectomy due to ovarian pathology or ovarian cancer in women with prior hysterectomy for benign gynecologic conditions at Chiang Mai University Hospital. Medical records of women who underwent hysterectomy for benign gynecologic diseases and pre-cancerous lesions between January 1, 2004 and December 31, 2013 at Chiang Mai Un...
