Resveratrol alleviates chemotherapy-induced oogonial stem cell apoptosis and ovarian aging in mice.

Resveratrol alleviates chemotherapy-induced oogonial stem cell apoptosis and ovarian aging in mice. Aging (Albany NY). 2019 Feb 14;11(3):1030-1044 Authors: Wu M, Ma L, Xue L, Ye W, Lu Z, Li X, Jin Y, Qin X, Chen D, Tang W, Chen Y, Hong Z, Zhang J, Luo A, Wang S Abstract Chemotherapy-induced ovarian aging not only increases the risk for early menopause-related complications but also results in infertility in young female cancer survivors. Oogonial stem cells have the ability to generate new oocytes and thus provide new opportunities for treating ovarian aging and female infertility. Resveratrol (3,5,4'-trihydroxy-trans-stilbene) is a natural phenol derived from plants, that has been shown to have positive effects on longevity and redox flow in lipid metabolism and a preventive function against certain tumors. To evaluate whether resveratrol could promote the repair of oogonial stem cells damage in a busulfan/cyclophosphamide (Bu/Cy)-induced accelerated ovarian aging model, female mice were administered 30 and 100 mg/kg/d resveratrol through a gavage for 2 weeks. We demonstrated that resveratrol (30 mg/kg/d) relieved oogonial stem cells loss and showed an attenuating effect on Bu/Cy-induced oxidative apoptosis in mouse ovaries, which may be attributed to the attenuation of oxidative levels in ovaries. Additionally, we also showed that Res exerted a dose-dependent effect on oogonial stem cells and attenuated H2O2-induced cytotoxicity and oxidative stress in...

This study evaluated the association between BRCA mutation status and serum anti-Müllerian hormone (AMH) level in young, reproductive-aged patients with breast cancer. Materials and Methods: Patients ≤ 40 years of age with breast cancer and who had known BRCA status and baseline serum AMH level at Samsung Medical Center, Seoul, Korea, were considered for inclusion. A total of 52 BRCA mutation carriers (27 BRCA1 and 25 BRCA2) and 264 non-carriers were selected for analyses. The serum level of AMH was compared according to presence of a BRCA mutation, and linear and logistic regression analyses were performed to eva...

Cancer treatment — and cancer itself — can threaten fertility. This is a tremendously important survivorship issue for many people. As an oncologist, I’m often asked questions about preserving fertility during cancer treatment. If this issue affects you, here is an overview of key options. When should you talk to your cancer team about fertility? Future children may not be foremost on your mind when you are diagnosed with cancer. Soon afterward, though, it’s worth talking to your doctor about fertility issues, if this is important to you now or might one day become important. Your doctor can explain...

This article reviews guidelines for surveillance of women with ovarian, endometrial, cervical, and vulvar cancer. It also reviews many of the long-term physical side effects of gynecologic cancer treatment including fatigue, neuropathy, lymphedema, cognitive dysfunction, sexual health concerns, menopausal symptoms, infertility, and economic stressors. Finally, survivorship care plans are reviewed as a tool for coordinating care for women with a history of gynecologic cancer.

When Noah Shulman was born a few days after Christmas 2016, his parents Kristelle and Evan had no reason to worry about him. The pregnancy went smoothly, and so did the birth. But within a few days of taking his first breath, Noah began to struggle. He wasn’t feeding, so he started losing weight. He was also lethargic. Several pediatricians reassured the Shulmans that they were probably just overly sensitive to Noah’s symptoms because Kristelle is a nurse and Evan is a physician assistant–a case of first-time-parent-white-coat syndrome. “They kind of dismissed us as neurotic parents,” says Eva...

Authors: Cui W, Stern C, Hickey M, Goldblatt F, Anazodo A, Stevenson WS, Phillips KA Abstract Alkylating chemotherapy is often used to treat pre-menopausal women for various malignancies and autoimmune diseases. Chemotherapy-associated ovarian failure is a potential consequence of this treatment which can cause infertility, and increases the risk of other long term adverse health sequelae. Randomised trials, predominantly of women undergoing alkylating chemotherapy for breast cancer, have shown evidence for the efficacy of gonadotropin-releasing hormone agonists (GnRHa) in preventing chemotherapy-associated ovarian...

A lot of people are very worried whether IVF is safe or not, and many infertile couples are not allowed to do IVF by their family members, because they are concerned about the side effects of IVF - both on the mother , and the baby. After all, they believe that in an IVF cycle we're pumping the mother full of powerful hormonal injections – surely these are going to have some adverse effects on the body.Thus, many people believe that these hormones increase the risk of breast cancer and ovarian cancer ; or that an IVF patient will run out of eggs faster and become menopausal sooner, because the IVF cycle “ uses ...

Conclusion: The patients of SLCT can present with hormonal magnification and manifest high AFP, CA125, and T levels. SLCT is characterized by a solid or mixed solid-cystic mass on CT/MR scans, and shows marked or moderated heterogeneous and constantly enhancement upon postcontrast study. The clinical characteristics and imaging findings are features and appropriated imaging should be performed whenever an SLCT is suspected.

Authors: Hayashi C, Chishima F, Matsumoto K, Kato E, Shinya K, Nakao T, Nakamura A, Yamamoto T Abstract Preservation of fertility has been recommended for cancer-bearing patients of reproductive age before undergoing cancer treatment. However, there are many considerations and it is difficult to preserve fertility for all patients undergoing therapy for malignancies. Female cancer survivors had lower pregnancy and live birth rates compared with others that underwent assisted reproductive technologies (ARTs). We should continue to consider the issue of infertility in patients who underwent therapies for malignancies...

CONCLUSION: Our results show that Epstein-Barr infection is possibly associated with autoimmune ovarian failure. The devastating impact on fertility in such disorder can be successfully avoided by in vitro maturation of oocytes from excised ovarian tissue. PMID: 29618356 [PubMed - in process]

ConclusionsThese findings suggest that a single dose of 5-FU is mildly ovotoxic, but any effects on ovarian function are likely transient because the primordial follicle population is not depleted. Collectively, these data support the notion that 5-FU is unlikely to impact on the long-term fertility of women.
