Establishing reproductive potential and advances in fertility preservation techniques for XY individuals with DSD (differences in sex development).

Clin Endocrinol (Oxf) 2019 Apr 20. Epub 2019 Apr 20.

Elizabeth Garrett Anderson UCL Institute of Women's Health, University College London Hospitals, 250 Euston Road, London, NW12PG.

Discordance between gonadal type and gender identity has often led to an assumption of infertility in patients with differences in sex development (DSD). However, there is now greater recognition of fertility being an important issue for this group of patients. Currently, gonadal tissue that may have fertility potential is not being stored for individuals with DSD and, where gonadectomy forms part of management, is often discarded. Read More

Authors:
Sumit Ghosh

Bioorg Chem 2019 Apr 11;88:102925. Epub 2019 Apr 11.

Department of Chemistry, Indian Institute of Technology Kanpur, Kanpur, Uttar Pradesh 208016, India. Electronic address:

Cisplatin or (SP-4-2)-diamminedichloridoplatinum(II) is one of the most potential and widely used drugs for the treatment of various solid cancers such as testicular, ovarian, head and neck, bladder, lung, cervical cancer, melanoma, lymphomas and several others. Cisplatin exerts anticancer activity via multiple mechanisms but its most acceptable mechanism involves generation of DNA lesions by interacting with purine bases on DNA followed by activation of several signal transduction pathways which finally lead to apoptosis. However, side effects and drug resistance are the two inherent challenges of cisplatin which limit its application and effectiveness. Read More

Long-Term Follow Up of the Erectile Function of Testicular Cancer Survivors.

Front Endocrinol (Lausanne) 2019 2;10:196. Epub 2019 Apr 2.

Laboratory of Seminology-Sperm Bank Loredana Gandini, Department of Experimental Medicine, Sapienza University of Rome, Rome, Italy.

The diagnosis of testicular cancer (TC) can have a considerable and persistent impact on a patient's sexuality, especially given its location. The high prevalence of TC in young adults, and the good prognosis, explain the great interest in sexual dysfunction and its influence on post-treatment quality of life. The aim of this study was to evaluate the impact of the diagnosis and treatments (inguinal orchiectomy and chemotherapy) on sex life. Read More

Role of Nodal signalling in testis development and initiation of testicular cancer.

Reproduction 2019 Apr 1. Epub 2019 Apr 1.

A Jorgensen, Department of Growth and Reproduction, Rigshospitalet, Kobenhavn, Denmark.

Testicular development from the initially bipotential gonad is a tightly regulated process involving a complex signalling cascade to ensure proper sequential expression of signalling factors and secretion of steroid hormones. Initially, Sertoli cell specification facilitates differentiation of the steroidogenic fetal Leydig cells and establishment of the somatic niche, which is critical in supporting the germ cell population. Impairment of the somatic niche during fetal life may lead to development of male reproductive disorders, including arrest of gonocyte differentiation, which is considered the first step in the testicular cancer pathogenesis.

"Hey, that could be me": The role of similarity in narrative persuasion.

PLoS One 2019 18;14(4):e0215359. Epub 2019 Apr 18.

University of Groningen, Groningen, The Netherlands.

Stories are often used in health communication because of accumulating evidence of their potential to affect people's attitudes and health behavioral intentions. Similarity between the reader and the story's protagonist appears to positively influence narrative persuasion, but the exact role of similarity on persuasive outcomes is debated, as some research finds clear effects of similarity manipulations whereas others do not. Possibly, these mixed results were found because the similarity manipulations were not always relevant to the topic of the story. Read More

Different Clinical Presentations and Management in Complete Androgen Insensitivity Syndrome (CAIS).

Int J Environ Res Public Health 2019 Apr 9;16(7). Epub 2019 Apr 9.

Pediatric Clinic, Department of Surgical and Biomedical Sciences, Università degli Studi di Perugia, 06132 Perugia, Italy.

Complete androgen insensitivity syndrome (CAIS) is an X-linked recessive genetic disorder resulting from maternally inherited or de novo mutations involving the androgen receptor gene, situated in the Xq11-q12 region. The diagnosis is based on the presence of female external genitalia in a 46, XY human individual, with normally developed but undescended testes and complete unresponsiveness of target tissues to androgens. Subsequently, pelvic ultrasound or magnetic resonance imaging (MRI) could be helpful in confirming the absence of Mullerian structures, revealing the presence of a blind-ending vagina and identifying testes.

Stem cells survive oncotherapy & can regenerate non-functional gonads: A paradigm shift for oncofertility.

Authors:
Deepa Bhartiya

Indian J Med Res 2018 Dec;148(Supplement):S38-S49

Stem Cell Biology Department, ICMR-National Institute for Research in Reproductive Health, Mumbai, India.

A large proportion of patients who survive cancer are rendered infertile as an unwanted side effect of oncotherapy. Currently accepted approaches for fertility preservation involve banking eggs/sperm/embryos or ovarian/testicular tissue before oncotherapy for future use. Such approaches are invasive, expensive, technically challenging and depend on assisted reproductive technologies (ART). Read More

Clock genes and cancer development in particular in endocrine tissues.

Endocr Relat Cancer 2019 Apr 1. Epub 2019 Apr 1.

G Chrousos, Pediatrics, National and Kapodistrian University of Athens - Faculty of Medicine, Athens, Greece.

Circadian rhythms in central and peripheral level are operated by transcriptional/translational feedback loops involving a set of genes called 'clock genes' that are implicated in the development of several diseases including malignancies. Dysregulation of Clock system can affect cancer susceptibility by regulating DNA damage and repair mechanisms as well as apoptosis. A number of oncogenic pathways can be dysregulated via clock genes' epigenetic alterations including hypermethylation of clock genes' promoters or variants of clock genes. Read More

A multicentre retrospective cohort study of ovarian germ cell tumours: Evidence for chemotherapy de-escalation and alignment of paediatric and adult practice.

Eur J Cancer 2019 Apr 4;113:19-27. Epub 2019 Apr 4.

Barts Health NHS Trust, West Smithfield, London, EC1A 7BE, UK; University College Hospital, 235 Euston Road London, NW1 2BU, UK; Centre for Molecular Oncology, Barts Cancer Institute, Queen Mary University of London, Charterhouse Square, London EC1M 6BQ, UK. Electronic address:

Background: Adult guidelines recommend BEP (bleomycin, etoposide, cisplatin) for all ovarian germ cell tumours, causing debilitating toxicities in young patients who will survive long term. Paediatricians successfully reduce toxicities by using lower bleomycin doses and substituting carboplatin for cisplatin, while testicular and paediatric immature teratomas (ITs) are safely managed with surgery alone.

Aim: The aim was to determine whether reduced-toxicity treatment could rationally be extended to patients older than 18 years. Read More

Pathogenesis of Testicular Germ Cell Neoplasia: A Conceptual Approach.

Adv Anat Pathol 2019 Apr 3. Epub 2019 Apr 3.

Department of Pathology, Hospital of the University of Pennsylvania, Philadelphia, PA.

Testicular germ cell tumors are a diverse group of neoplasms, consisting of the prepubertal type 1 tumors, pure teratoma, and pure yolk sac tumor, the type 2 tumors, which are biologically malignant, preceded by germ cell neoplasia in situ, and harbor chromosome 12p abnormalities, and the type 3 tumor, spermatocytic tumor, which features chromosome 9p amplification. These arise in distinct clinical settings, and harbor distinct genetic abnormalities, immunohistochemical properties, and morphologic features. Here we have attempted to unify embryology, morphology, immunohistochemistry, and genetics in order to distill this fascinating group of neoplasms into what we hope is a useful framework for understanding their classification.

Testicular Cancer in Infertile Men With and Without Testicular Microlithiasis: A Systematic Review and Meta-Analysis of Case-Control Studies.

Front Endocrinol (Lausanne) 2019 21;10:164. Epub 2019 Mar 21.

Andrology Unit, Department of Clinical Medicine, Public Health, Life and Environment Sciences, University of L'Aquila, L'Aquila, Italy.

An association between testicular microlithiasis (TM) and both carcinoma (CIS) of the testis and testicular germ cell tumors (TGCTs) has been reported. Furthermore, TM seems to be significantly more prevalent in men with male-factor infertility, representing itself a risk factor for TGCT. Nevertheless, the evidence of the association of TM with a higher prevalence of testicular cancer in infertile men remains inconclusive. Read More

Association Study Among Candidate Genetic Polymorphisms and Chemotherapy-Related Severe Toxicity in Testicular Cancer Patients.

Front Pharmacol 2019 8;10:206. Epub 2019 Mar 8.

Laboratory of Chemical Carcinogenesis and Pharmacogenetics, Department of Basic and Clinical Oncology, Faculty of Medicine, University of Chile, Santiago, Chile.

Testicular cancer is one of the most commonly occurring malignant tumors in young men with fourfold higher rate of incidence and threefold higher mortality rates in Chile than the average global rates. Surgery is the initial line of treatment for testicular cancers, and is generally followed by chemotherapy, usually with combinations of bleomycin, etoposide, and cisplatin (BEP). However, the adverse effects of chemotherapy vary significantly among individuals; therefore, the present study explored the association of functionally significant allelic variations in genes related to the pharmacokinetics/pharmacodynamics of BEP and DNA repair enzymes with chemotherapy-induced toxicity in BEP-treated testicular cancer patients.

Extramitochondrial cardiolipin suggests a novel function of mitochondria in spermatogenesis.

J Cell Biol 2019 Mar 26. Epub 2019 Mar 26.

Department of Anesthesiology, New York University School of Medicine, New York, NY

Mitochondria contain cardiolipin (CL), an organelle-specific phospholipid that carries four fatty acids with a strong preference for unsaturated chains. Unsaturation is essential for the stability and for the function of mitochondrial CL. Surprisingly, we found tetrapalmitoyl-CL (TPCL), a fully saturated species, in the testes of humans and mice.

[Testicular germ cell tumors: Histopathological and molecular features].

Bull Cancer 2019 Apr 21;106(4):328-341. Epub 2019 Mar 21.

Hôpital Foch, service d'anatomie et cytologie pathologiques, 40, rue Worth, 92150 Suresnes, France; Institut Curie, service de pathologie, 35, rue Dailly, 92240 Saint Cloud, France. Electronic address:

In 2016, the WHO classification of testicular germ cell tumors was revised considering advances in the understanding of their tumorigenesis and molecular features. This restructuring led to a division into two major groups with, on one hand, prepubertal-type tumors, not derived from germ cell neoplasia in situ (GCNIS), and on the other hand, postpubertal-type tumors, GCNIS-derived, which occur in youg men (seminoma and non seminomatous germ cell tumors - embryonal carcinoma, yolk sac tumor, teratoma and choriocarcinoma essentially). The term germ cell neoplasia in situ is consensually accepted as a new terminology for the precursor lesion. Read More

Autologous grafting of cryopreserved prepubertal rhesus testis produces sperm and offspring.

Science 2019 03;363(6433):1314-1319

Molecular Genetics and Developmental Biology Graduate Program, University of Pittsburgh School of Medicine, Pittsburgh, PA, USA.

Testicular tissue cryopreservation is an experimental method to preserve the fertility of prepubertal patients before they initiate gonadotoxic therapies for cancer or other conditions. Here we provide the proof of principle that cryopreserved prepubertal testicular tissues can be autologously grafted under the back skin or scrotal skin of castrated pubertal rhesus macaques and matured to produce functional sperm. During the 8- to 12-month observation period, grafts grew and produced testosterone. Read More
