Testicular cancer is the most common malignancy in young men. We discuss four cases of germ cell tumours (GCTs) presenting to general practitioners and physicians where there were notable preventable delays in the diagnosis and management. This diagnostic delay is associated with a more advanced stage of disease, and subsequent increased treatment-related morbidity and decreased survival. Our series highlights the variety of ways in which GCTs may present and we discuss the importance of prompt diagnosis through a thorough history and examination, early measurement of serum tumour markers and appropriate multidisciplinary team discussion. GCTs are highly curable cancers in the majority of patients and delays in management can, therefore, have devastating consequences.

A human induced pluripotent stem cell (iPSC) line was generated from patient with Kennedy Disease (KD), who carried the CAG repeat expansion mutation in AR gene. Peripheral blood mononuclear cells (PBMCs) were reprogrammed using non-integrating delivery of KFL4, OCT4, SOX2, BCL-XL and c-MYC. The iPSC line expresses pluripotency markers, displays a normal karyotype, and is capable of differentiate into three germ layers in vitro.

Libido plays a crucial role in influencing semen quality, yet the underlying regulatory mechanisms remain unclear. As a central axis in male goose reproduction, the hypothalamic-pituitary-testicular-external genitalia (HPTE) axis may contribute to the regulation of this process. In this study, we established a rating scale for goose libido based on average number of massages to erection (ANM) and the erection type, and evaluated semen quality across the entire flock.

Skin and hair development is regulated by multitude of programs of activation and silencing of gene expression to maintain normal skin and hair follicle (HF) development, homeostasis, and cycling. Here, we have identified E74-like factor 5 (Elf5) transcription factor, as a novel regulator of keratinocyte proliferation and differentiation processes in skin. Expression analysis has revealed that Elf5 expression was localised and elevated in stem/progenitor cell populations of both the epidermis (basal and suprabasal) and in HF bulge and hair germ stem cell (SCs) compartments during skin and hair development and cycling.

Background: Few studies have examined childbirth and adverse perinatal outcomes among male adolescents and young adults with cancer (AYAs, diagnosed at age 15-39 years). We conducted a population-based assessment of these outcomes in a large, diverse sample.
Methods: Male AYAs diagnosed between January 1, 1995 and December 31, 2015 were identified using the Texas Cancer Registry and linked to live birth certificates and the Texas Birth Defects Registry through December 31, 2016.
