Semen quality in patients with testicular cancer is associated with age and with greatly elevated levels of beta human chorionic gonadotropin

open access: yesAndrology, EarlyView.
Abstract Background Poor semen quality is a well‐known feature in patients with testicular germ cell tumours (GCTs) at the time of diagnosis but the underlying biological reasons are incompletely understood. Objectives This study aimed to identify GCT‐specific clinical factors that are involved with poor semen quality in GCT patients.

Pharmacogenetics of follicle‐stimulating hormone action in the male

open access: yesAndrology, EarlyView.
Abstract Male factor infertility (MFI) is involved in half of the cases of couple infertility. The follicle‐stimulating hormone (FSH) therapy is considered efficient to improve semen parameters and pregnancy rate in patients with idiopathic MFI, following the lesson learned from hypogonadotropic hypogonadism.

The role of iron in normal and impaired testicular function

open access: yesAndrology, EarlyView.
Abstract Iron plays a critical role in testicular physiology, impacting spermatogenesis, testosterone production, and overall testicular function. Iron homeostasis is maintained through systemic and cellular regulatory mechanisms, including hepcidin‐mediated systemic iron control and the iron‐responsive element/iron regulatory protein (IRE/IRP) system ...

Maternal, childhood and adolescent influences on Leydig cell functional capacity and circulating INSL3 concentration in young adults: Importance of childhood infections and body mass index

open access: yesAndrology, EarlyView.
Abstract Background The constitutive Leydig cell hormone insulin‐like peptide 3 (INSL3) is considered a good estimate of the adult Leydig cell functional capacity and appears to remain relatively consistent throughout adult male life, only gradually declining into old age.

Semen Cryopreservation in Testicular Cancer: Before or After Orchidectomy?

open access: yesAndrology, EarlyView.
ABSTRACT Background Fertility preservation in patients with testicular cancer remains a clinical priority, yet the optimal timing for sperm cryopreservation—before or after orchidectomy—remains a matter of debate. Objectives The aim of this study was to determine the optimal timing for semen cryopreservation and the best‐quality sample for ART.

A concept for a new approach to combined oral contraception from adolescence to perimenopause: Continuous use of the oral GnRH antagonist Relugolix and the fetal estrogen Estetrol

open access: yesActa Obstetricia et Gynecologica Scandinavica, EarlyView.
It is expected that the relugolix estetrol combination RE4W will enable women to control their fertility and prevent menstrual cycle related problems, while offering a smooth transition through perimenopause into the postmenopause and decrease the risk of breast cancer.
