Women carrying a BRCA mutation have an increased risk of developing breast and ovarian cancer. The most effective strategy to reduce this risk is the bilateral salpingo-oophorectomy, with or without additional risk-reducing mastectomy. Risk-reducing bilateral salpingo-oophorectomy (RRBSO) is recommended between age 35 and 40 and between age 40 and 45 years for women carriers of BRCA1 and BRCA2 mutations, respectively. Consequently, most BRCA mutation carriers undergo this procedure prior to a natural menopause and develop an anticipated lack of hormones. This condition has a detrimental impact on various systems, affecting both the quality of life and longevity; in particular, women carrying BRCA1 mutation, who are likely to have surgery earlier as compared to BRCA2. Hormonal replacement therapy (HRT) is the only effective strategy able to significantly compensate the hormonal deprivation and counteract menopausal symptoms, both in spontaneous and surgical menopause. Although recent evidence suggests that HRT does not diminish the protective effect of RRBSO in BRCA mutation carriers, concerns regarding the safety of estrogen and progesterone intake reduce the use in this setting. Furthermore, there is strong data demonstrating that the use of estrogen alone after RRBSO does not increase the risk of breast cancer among women with a BRCA1 mutation. The additional progesterone intake, mandatory for the protection of the endometrium during HRT, warrants further studies. However, when hysterectomy is performed at the time of RRBSO, the indication of progesterone addition decays and consequently its potential effect on breast cancer risk. Similarly, in patients conserving the uterus but undergoing risk-reducing mastectomy, the addition of progesterone should not raise significant concerns for breast cancer risk anymore. Therefore, BRCA mutation carriers require careful counselling about the scenarios following their RRBSO, menopausal symptoms or the fear associated with HRT use.

Review
Without preventive interventions, women with germline pathogenic variants in or have high lifetime risks for breast cancer and tubo-ovarian cancer. The increased risk for breast cancer starts at a considerably younger age than that for tubo-ovarian cancer. Risk-reducing bilateral salpingo-oophorectomy (rrBSO) is effective in reducing tubo-ovarian cancer risk for and mutation carriers, but whether it reduces breast cancer risk is less clear. All studies of rrBSO and breast cancer risk are observational in nature and subject to various forms of bias and confounding, thus limiting conclusions that can be drawn about causation. Early studies supported a statistically significant protective association for rrBSO on breast cancer risk, which is reflected by several international guidelines that recommend consideration of premenopausal rrBSO for breast cancer risk reduction. However, these historical studies were hampered by the presence of several important biases, including immortal person-time bias, confounding by indication, informative censoring, and confounding by other risk factors, which may have led to overestimation of any protective benefit. Contemporary studies, specifically designed to reduce some of these biases, have yielded contradictory results. Taken together, there is no clear and consistent evidence for a role of premenopausal rrBSO in reducing breast cancer risk in or mutation carriers.

Obstetrics and Gynecology May 2022To evaluate trends in the incidence of premenopausal unilateral and bilateral oophorectomy between 1950 and 2018.
OBJECTIVE
To evaluate trends in the incidence of premenopausal unilateral and bilateral oophorectomy between 1950 and 2018.
METHODS
The Rochester Epidemiology Project medical records-linkage system was used to identify all women aged 18-49 years who were residents of Olmsted County, Minnesota, and underwent unilateral or bilateral oophorectomy before spontaneous menopause between January 1, 1950, and December 31, 2018. Population denominators were derived from the U.S. Decennial Censuses for the years 1950-2010, and intercensal year population denominators were linearly interpolated. For 2011-2018, the annual population denominators were obtained from the U.S. Census projections. Where appropriate, overall incidence rates were age-adjusted to the total U.S. female population from the 2010 Census.
RESULTS
There were 5,154 oophorectomies in Olmsted County across the 69-year period between 1950 and 2018, and 2.9% showed malignant disease on pathology. A total of 2,092 (40.6%) women underwent unilateral oophorectomy, and 3,062 (59.4%) women underwent bilateral oophorectomy. More than half (n=1,750, 57.2%) of the bilateral oophorectomies occurred between 1990 and 2009. Until 1975-1979, the incidence of unilateral oophorectomy was mostly higher than bilateral oophorectomy. From 1980-1984 until 2000-2004, the incidence of bilateral oophorectomy more than doubled and the incidence of unilateral oophorectomy declined. After 2005, both procedures declined and converged to a similar incidence in 2015-2018. The decline in premenopausal bilateral oophorectomy over the past 14 years (2005-2018) was most pronounced for women who underwent oophorectomy concurrently with hysterectomy or did not have any ovarian indication.
CONCLUSION
The incidence rates of unilateral and bilateral oophorectomy have varied greatly across the 69-year period of this study. In the past 14 years, the incidence of premenopausal unilateral and bilateral oophorectomy has decreased. These trends reflect the effects of the initial 2005-2006 publications and the subsequent expanding body of evidence against the practice of oophorectomy for noncancer indications.

In this invited review, we discuss some unresolved and controversial issues concerning premature (<40 years) or early (40-45 years) bilateral oophorectomy. First, we clarify the terminology. Second, we summarize the long-term harmful consequences of bilateral oophorectomy. Third, we discuss the restrictive indications for bilateral oophorectomy in premenopausal women to prevent ovarian cancer that are justified by the current scientific evidence. Fourth, we explain the importance of estrogen replacement therapy when bilateral oophorectomy is performed. Hormone replacement therapy is indicated after bilateral oophorectomy until the age of expected natural menopause like in premature or early primary ovarian insufficiency. Fifth, we discuss the relationship between adverse childhood experiences, adverse adult experiences, mental health, gynecologic symptoms and bilateral oophorectomy. The acceptance and popularity of bilateral oophorectomy over several decades, and its persistence even in the absence of supporting scientific evidence, suggest that non-medical factors related to sex, gender, reproduction, cultural beliefs and socioeconomic structure are involved. We discuss some of these non-medical factors and the need for more research in this area.

Bilateral salpingo-oophorectomy (BSO) is a risk management approach with strong evidence of mortality reduction for women with germline mutations in the tumor suppressor genes BRCA1 and BRCA2 (BRCA1/2). Few studies to date have evaluated uptake of BSO in women from diverse racial and ethnic backgrounds who carry BRCA1/2 mutations. The objective of the UPTAKE study was to explore rates and predictors of risk-reducing BSO among Latinas affected and unaffected with breast cancer who had a deleterious BRCA1/2 mutation. We recruited 100 Latina women with deleterious BRCA1/2 mutations from community hospitals, academic health systems, community, and advocacy organizations. Women completed interviews in Spanish or English. We obtained copies of genetic test reports for participants who provided signed medical release. After performing threefold cross-validation LASSO for variable selection, we used multiple logistic regression to identify demographic and clinical predictors of BSO. Among 100 participants, 68 had undergone BSO at the time of interview. Of these 68, 35 were US-born (61% of all US-born participants) and 33 were not (77% of the non-US-born participants). Among Latinas with BRCA1/2 mutations, older age (p = 0.004), personal history of breast cancer (p = 0.003), higher income (p = 0.002), and not having a full-time job (p = 0.027) were identified as variables significantly associated with uptake of BSO. Results suggest a high rate of uptake of risk-reducing BSO among a sample of Latinas with BRCA1/2 mutations living in the US. We document factors associated with BSO uptake in a diverse sample of women. Relevant to genetic counseling, our findings identify possible targets for supporting Latinas' decision-making about BSO following receipt of a positive BRCA1/2 test.

Review
Surgical Menopause and Bilateral Oophorectomy: Effect of Estrogen-Progesterone and Testosterone Replacement Therapy on Psychological Well-being and Sexual Functioning; A Systematic Literature Review.
BACKGROUND
Besides experiencing vasomotor symptoms, after surgical menopause and bilateral salpingo-oophorectomy (BSO), women experience moderate to severe psychological and sexual symptoms.
AIMS
To systematically review and meta-analyze the effect of systemic hormone replacement therapy (sHRT) on psychological well-being and sexual functioning in women after surgical menopause and BSO.
METHODS
Medline/Pubmed, EMBASE and PsychInfo were systematically searched until November 2021. Randomized controlled trials investigating the effect of sHRT on psychological well-being and/or sexual functioning in surgically menopausal women and women after BSO were eligible for inclusion. Two independent authors performed study selection, risk of bias assessment and data extraction. Standardized mean differences (SMDs) were calculated.
OUTCOMES
Primary outcomes for psychological well-being were defined as overall psychological well-being, depression, and anxiety. Primary outcomes for sexual functioning were defined as overall sexual functioning, sexual desire, and sexual satisfaction. All outcomes were assessed on short (≤12 weeks) or medium term (13-26 weeks).
RESULTS
Twelve studies were included. Estradiol had a beneficial effect on depressed mood on short term 3-6 years after surgery or 2 years (median) after surgery with high heterogeneity (SMD: -1.37, 95%CI: -2.38 to -0.37, P = .007, I 79%). Testosterone had a beneficial effect on overall sexual functioning on short to medium term 4.6 years (mean) after surgery (SMD 0.38, 95%CI 0.11-0.65, I 0%) and on sexual desire on medium term at least 3-12 months after surgery (SMD 0.38, 95%CI 0.19-0.56, I 54%). For most studies, risk of bias was uncertain.
CLINICAL IMPLICATIONS
Estradiol may beneficially affect psychological symptoms after surgical menopause or BSO and testosterone might improve sexual desire and overall sexual functioning.
STRENGTHS AND LIMITATIONS
This review only included patient-reported outcomes, thereby reflected perceived and not simply objective symptoms in surgically menopausal women and women after BSO. The small number of studies highly varied in nature and bias could not be excluded, therefore our results should be interpreted with great caution.
CONCLUSION
Independent randomized controlled clinical trials investigating the effects of estrogen-progesterone and testosterone on psychological and sexual symptoms after surgical menopause are needed.

The Journals of Gerontology. Series A,... Sep 2017The cause-effect relationship between bilateral oophorectomy and accelerated aging remains controversial. We conducted new analyses to further address this controversy.
BACKGROUND
The cause-effect relationship between bilateral oophorectomy and accelerated aging remains controversial. We conducted new analyses to further address this controversy.
METHODS
The Rochester Epidemiology Project records-linkage system was used to identify all premenopausal women who underwent bilateral oophorectomy for a noncancerous condition before age 50 years between 1988 and 2007 in Olmsted County, MN. Each woman was randomly matched to a referent woman born in the same year (±1 year) who had not undergone bilateral oophorectomy. We studied the rate of accumulation of 18 common chronic conditions over a median of approximately 14 years of follow-up (historical cohort study). Analyses were restricted to women free of any of the 18 chronic conditions at the time of oophorectomy (or index date).
RESULTS
After adjustments for race/ethnicity, education, body mass index, smoking, and age and calendar year at the index date, women who underwent oophorectomy before age 46 years experienced an accelerated rate of accumulation of the 18 chronic conditions considered together (hazard ratio = 1.24; 95% confidence interval: 1.12, 1.37; p < .001). The single-year incidence rate of new conditions was most different in the first 6 years after oophorectomy but the difference attenuated thereafter. Findings did not vary by surgical indication for the oophorectomy.
CONCLUSIONS
Bilateral oophorectomy is associated with a higher risk of multimorbidity among women who did not have any of the 18 selected conditions at baseline. The association did not vary by surgical indication for oophorectomy. Our findings suggest that bilateral oophorectomy is causally linked to accelerated aging.

BACKGROUND
Whether oophorectomy reduces breast cancer risk among BRCA mutation carriers is a matter of debate. We undertook a prospective analysis of bilateral oophorectomy and breast cancer risk in BRCA mutation carriers.
METHODS
Subjects had no history of cancer, had both breasts intact, and had information on oophorectomy status (n = 3722). Women were followed until breast cancer diagnosis, prophylactic bilateral mastectomy, or death. A Cox regression model was used to estimate the hazard ratios (HRs) and 95% confidence intervals (CIs) of breast cancer associated with oophorectomy (coded as a time-dependent variable). All statistical tests were two-sided.
RESULTS
Over a mean follow-up of 5.6 years, 350 new breast cancers were diagnosed. Among women with a BRCA1 or BRCA2 mutation, oophorectomy was not associated with breast cancer risk compared with women who did not undergo an oophorectomy. The age-adjusted hazard ratio associated with oophorectomy was 0.96 (95% CI = 0.73 to 1.26, P = 76) for BRCA1 and was 0.65 (95% CI = 0.37 to 1.16, P = 14) for BRCA2 mutation carriers. In stratified analyses, the effect of oophorectomy was statistically significant for breast cancer in BRCA2 mutation carriers diagnosed prior to age 50 years (age-adjusted HR = 0.18, 95% CI = 0.05 to 0.63, P = 007). Oophorectomy was not associated with risk of breast cancer prior to age 50 years among BRCA1 mutation carriers (age-adjusted HR = 0.79, 95% CI = 0.55 to 1.13, P = 51).
CONCLUSIONS
Findings from this large prospective study support a role of oophorectomy for the prevention of premenopausal breast cancer in BRCA2, but not BRCA1 mutation carriers. These findings warrant further evaluation.

BACKGROUND
Little is known about the long-term risks of stroke and ischemic heart disease (IHD) in women who had a hysterectomy alone (HA) or with bilateral oophorectomy (HBO) for benign diseases, particularly in China where the burden of cardiovascular diseases (CVD) is high. We assessed mean levels of cardiovascular risk factors and relative risks of stroke and IHD in Chinese women who had a HA or HBO.
METHODS
A total of 302 510 women, aged 30 to 79 years were enrolled in the China Kadoorie Biobank from 2004 to 2008 and followed up for a mean of 9.8 years. The analysis involved premenopausal women without prior cardiovascular disease or cancer at enrollment. We calculated adjusted hazard ratios for incident cases of CVD and their pathological types (ischemic stroke, hemorrhagic stroke, and IHD) after HA and HBO. Analyses were stratified by age and region and adjusted for levels of education, household income, smoking status, alcohol consumption, physical activity, body mass index, systolic blood pressure, diabetes, self-reported health, and number of pregnancies.
RESULTS
Among 282 722 eligible women, 8478 had HA, and 1360 had HBO. Women who had HA had 9% higher risk of CVD after HA (hazard ratio, 1.09 [95% CI, 1.06-1.12]) and 19% higher risk of CVD after HBO (1.19 [95% CI, 1.12-1.26]) compared with women who did not. Both HA and HBO were associated with higher risks of ischemic stroke and IHD but not with hemorrhagic stroke. The relative risks of CVD associated with HA and HBO were more extreme at younger age of surgery.
CONCLUSIONS
Women who had either HA or HBO have higher risks of ischemic stroke and IHD, and these risks should be evaluated when discussing these interventions. Additional screening for risk factors for CVD should be considered in women following HA and HBO operations, especially if such operations are performed at younger age.

BACKGROUND
Gynecologic surgery is hypothesized to reduce risk of breast cancer; however, associations may be modified by subsequent hormone use. Our objective was to examine the association between gynecologic surgery and breast cancer incidence considering the use of hormone therapy.
METHODS
The Sister Study is a prospective cohort of initially breast cancer-free women aged 35-74 years with a sister who had breast cancer. We used Cox proportional hazards models to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for the association between gynecologic surgery (no surgery, hysterectomy only, bilateral oophorectomy with or without hysterectomy) and incident breast cancer among 50 701 women.
RESULTS
History of gynecologic surgery was common, with 13.8% reporting hysterectomy only and 18.1% reporting bilateral oophorectomy with or without hysterectomy. During follow-up (median = 11.4 years), 3948 cases were diagnosed. Compared with no surgery, bilateral oophorectomy was inversely associated with breast cancer (HR = 0.91, 95% CI = 0.83 to 1.00), and hysterectomy alone was positively associated (HR = 1.12, 95% CI = 1.02 to 1.23). Compared with no surgery and no hormone therapy, bilateral oophorectomy combined with estrogen only therapy (HR = 0.83, 95% CI = 0.74 to 0.94) was inversely associated with breast cancer, while hysterectomy combined with estrogen plus progestin therapy was positively associated with breast cancer (HR = 1.25, 95% CI = 1.01 to 1.55).
CONCLUSIONS
We observed an inverse association between bilateral oophorectomy and breast cancer risk. The positive association between hysterectomy and breast cancer may be due to concomitant estrogen plus progestin therapy.
