Sexual health and wellbeing and the menopause: An EMAS clinical guide.

Introduction: Sexual health and wellbeing are significant aspects of quality of life. However, taking a sexual history is often avoided in medical practice, leaving a void in management and awareness. As the menopause can have a major impact on sexual health, it is imperative that healthcare providers are appropriately trained in sexual health and wellbeing and the aligned disciplines in order to achieve optimal care.

EMAS position statement: Thyroid disease and menopause.

Introduction: Thyroid diseases are common in women in their late reproductive years; therefore, thyroid disease and menopause may co-exist. Both conditions may present with a wide range of symptoms, leading to diagnostic challenges and delayed diagnosis. Aim To construct the first European Menopause and Andropause Society (EMAS) statement on thyroid diseases and menopause.

Evaluating the safety and efficacy of cryopreserved ovarian tissue transplantation in leukemia patients with different bone marrow remission status using xenotransplantation.

Background: Leukemia patients undergoing cryopreserved ovarian tissue transplantation (OTT) may carry a high risk of disease induction. Measurable residual disease (MRD) in bone marrow is linked to an elevated risk of relapse. It is controversial whether leukemia patients must be allowed to achieve measurable residual disease negative (MRD-negative) status instead of measurable residual disease positive (MRD-positive) status before ovarian tissue cryopreservation (OTC).

Practice guideline on ovarian tissue cryopreservation and transplantation in the prevention and treatment of iatrogenic premature ovarian insufficiency.

Premature ovarian insufficiency (POI) refers to the decline of ovarian function before the age of 40. POI causes a reduction in or loss of female fertility, accompanied by different degrees of menopausal symptoms, which increases the risk of chronic diseases related to early menopause and seriously affects patients' quality of life and health. It is conservatively estimated that at least one million prepubertal girls and women of reproductive age in China are at risk of iatrogenic POI caused by radiotherapy and chemotherapy every year.

Effects of different volumes of ovariectomy on fertility and offspring development of rats.

Objective: The purpose of this study was to explore the effect of removal of different volumes of ovarian tissue on fertility and offspring development of SD rats.

Methods: SD rats were randomly divided into 6 groups according to different volumes of ovariectomy: Sham group (n=6), non-ovariectomized; 25%-OVX group (n=6), with half of the left ovary excised; 50%-OVX group (n=5), with the left ovary excised; 75%-OVX group (n=5), with the left ovary and half of the right ovary excised; 87.5%-OVX group (n=6), with the left ovary and three quarters of the right ovary excised; 100%-OVX group (n=6), with bilateral ovaries excised.

EMAS position statement: Testosterone replacement therapy in older men.

Introduction: Late-onset hypogonadism is the clinical entity characterised by low testosterone concentrations associated with clinical symptoms in the absence of organic disease in ageing men. It has been associated with metabolic syndrome, reduced bone mineral density, and increased cardiovascular morbidity and mortality risk. Although testosterone replacement therapy (TRT) reverses most of these conditions in young hypogonadal men, the risk/benefit ratio of TRT in older men is debatable.

Traditional Chinese medicine Dingkun pill to increase fertility in women with a thin endometrium-a prospective randomized study.

Objective: The aim of this study is to optimize the treatment methods of infertility, which is suggested to be mainly caused by thin endometrium, using a special form of traditional Chinese medicine, the Dingkun pill (DKP), to increase the beneficial endometrial effect of conventional hormone/progestogen therapy.

Methods: A total of 307 patients visiting our specialized gynecological endocrinology department because of infertility, which we suggested to be caused by thin endometrium [endometrial thickness (EMT) < 7 mm], were randomly assigned to the experimental group and the control group. The experimental group was treated with estradiol + sequential dydrogesterone + DKP (every day); the control group received hormonal treatment without the Chinese medicine.

Methods: Prospective, randomized, open-labeled 3-monthly study; 104 patients (aged 20-40 years) receiving either ZGNZC (experimental group,  = 55) or not (control group,  = 49). Main outcomes: thickness/type of the endometrium during ovulation and pregnancy rate.

Prevalence of diminished ovarian reserve in Chinese women with follicular cysts and menstrual disorders.

Objectives: To assess the prevalence of diminished ovarian reserve (DOR) in Chinese women with follicular cysts and menstrual disorders and relationship to hormonal markers.

Methods: 117 women with follicular cysts and menstrual disorders, aged 24 ∼ 53 (39.19 ± 6.

Clinical Importance of PGRMC1 in Hormone Responsive Breast Cancer.

Background: For the development of PGRMC1, a multifunctional receptor belonging to membrane-associated progesterone receptor proteins (MAPR) family, as possible predictive marker for increased hormone-dependent breast cancer (BC) risk, a systematic research program has been performed, starting with different BC cells, continued with animal studies and finally with clinical studies with BC patients.

Summary: In vitro studies showed dose- and time-dependent BC cell proliferations with all available synthetic progestogens (not with progesterone), but mostly significant only in the presence of PGRMC1. Different animal (xenograft) studies confirmed that synthetic progestogens, but not progesterone and dydrogesterone, increased the estradiol-induced tumor proliferation, although with dydrogesterone, a small time-dependent increase could be seen.

Sexual function in Chinese women with different clinical phenotypes of polycystic ovary syndrome.

To investigate sexual function stratified according to four clinical phenotypes of polycystic ovary syndrome (PCOS) and its association with clinical and quality of life parameters, and to compare these with healthy controls in Chinese women with PCOS. A cross-sectional study was designed in 1000 PCOS women and 500 control women aged 18-45 years. PCOS women were grouped into four clinical phenotypes according to the Rotterdam Criteria.

EMAS position statement: Vitamin D and menopausal health.

Introduction: There is increasing evidence that vitamin D has widespread tissue effects. In addition to osteoporosis, vitamin D deficiency has been associated with cardiovascular disease, diabetes, cancer, infections and neurodegenerative disease. However, the effect of vitamin D supplementation on non-skeletal outcomes requires clarification, especially in postmenopausal women.

Ovarian tissue cryopreservation for a 3-year-old girl with Mosaic Turner syndrome in China: First case report and literature review.

Background: Although it cannot be predicted accurately which young females will develop premature ovarian insufficiency (POI) following chemotherapy or irradiation, patients at high risk of POI should be offered ovarian tissue cryopreservation (OTC). Our ovarian tissue cryobank is the first center in China. OTC was firstly performed on a 3-year-old girl with mosaic Turner syndrome (TS) in China.

Effects of hypoxia-preconditioned HucMSCs on neovascularization and follicle survival in frozen/thawed human ovarian cortex transplanted to immunodeficient mice.

Background: The massive loss of follicles in the early stage of ovarian tissue transplantation is considered a significant restriction to the efficacy of ovarian tissue cryopreservation (OTC) and transplantation (OT). The use of mesenchymal stem cells (MSCs) before transplantation of ovarian fragments shortened the hypoxic period and boosted neovascularization. Hypoxia-preconditioned MSCs can enhance the potential of angiogenesis.
