A Search for Disorders of Sex Development among Infertile Men

In conclusion, the frequency of DSD in this study was 14%, consisting mainly of sex chromosome abnormalities but also 46,XX and 46,XY DSD. However, this figure may increase as further investigations are conducted in idiopathic cases with signs of primary testicular failure, which may present partial gonadal dysgenesis.Sex Dev

CONCLUSION: When gastroenterologists encounter NAFLD/NASH patients, serum CK should be verified. If hyperCKemia, frontal baldness, a hatched face, history of cataract surgery, and grip myotonia are noted, the possibility of MD may be considered. PMID: 33033573 [PubMed]

Authors: Tvrdá E, Michalko J, Árvay J, Vukovic NL, Ivanišová E, Ďuračka M, Matušíková I, Kačániová M Abstract Schisandra chinensis is a woody vine native to China, Korea, and Russia, which has been used as a traditional herbal remedy to treat male infertility. As very little information is available concerning its effects on ejaculated spermatozoa, the aim of this study was to investigate the chemical, antioxidant, and antibacterial properties of the S. chinensis berry (Omija) extract followed by an assessment of its in vitro effects on bovine sperm ...

AbstractBackgroundThe American Society of Clinical Oncology guidelines recommend early referral to reproductive endocrinology and infertility (REI) specialists for young women diagnosed with breast cancer. Current practice patterns demonstrate an increased utilization of neoadjuvant chemotherapy (NAC). We evaluated premenopausal women with breast cancer after consultation with a Fertility Nurse Specialist (FNS) and determine factors associated with referral to REI specialists.MethodsThis retrospective review included all premenopausal women diagnosed at our institution with stage 0 –III unilateral breast cancers betw...

Over the last years, increasing evidence has focused on crucial pathogenetic role of PRL on malignant, premalignant and benign uterine diseases. Studies in animals and humans have documented that PRL receptors (PRL-Rs) are widely expressed on uterine cells and that PRL is directly synthesized by the endometrium under the stimulatory action of progesterone. Uterine PRL secretion is finely modulated by autocrine/paracrine mechanisms which do not depend on the same control factors implied in the regulation of PRL secretion from pituitary. On the other hand, PRL is synthesized also in the myometrium and directly promotes uteri...

AbstractThe conspicuous absence of personal articulations of miscarriage in mainstream discourses attests to the stigmatised nature of the experience. Notably, there exists a growing body of infertility comics which foreground the authors ’ lived realities of miscarriage. In a close reading of select graphic memoirs such as Jenell Johnson’sPresent/Perfect, Paula Knight ’sThe Facts of Life, Phoebe Potts ’Good Eggs, and Diane Noomin ’sBaby Talk, this article examines how the authors use comics to foreground their predicament. In so doing, the essay argues that these narratives attempt to accord ...

Purpose of review The review presents a clinical algorithm for the evaluation and treatment for adolescents with Klinefelter's syndrome who desire fertility preservation. Recent findings Sperm is present in the ejaculate in around 8% of men with Klinefelter's syndrome. Although most are severely oligospermic/azoospermic, 43–45% of men will have sperm found during a testicular sperm extraction, reaching up to 70% in adolescents. Summary Klinefelter's syndrome (47, XXY) causes hypogonadotophic hypogonadism and severe oligospermia/azoospermia rendering natural conception rare. During puberty, boys often require ...

Klinefelter syndrome (KS) is the most frequent chromosome disorder in males (1:650 newborn males), defined by 47,XXY karyotype. The classical phenotype is that of a tall male with relatively long legs, small, firm testes and gynecomastia. Azoospermia and infertility are almost inevitably present, but may be overcome by TESE and ICSI. Nevertheless, a broad spectrum of phenotypes has been described and>70% of the actually existing KS men may remain undiagnosed throughout their lifespan. Accordingly, hypogonadism is usually not evident until early adulthood and progresses with ageing.
