Assessing physiological, behavioral and movement responses to Suprelorin implant delivery methods in free‐ranging eastern grey kangaroos Macropus giganteus

Wildlife Biology, EarlyView.
Overabundant populations of eastern grey kangaroos Macropus giganteus in peri‐urban areas pose ecological and social challenges. Current management strategies are often hindered by animal welfare and logistical concerns. This study aimed to assess stress responses of kangaroos to two contraceptive delivery methods.

Molecular Mechanisms of Dysregulated LH and FSH Secretion in Human Reproductive Failure

Biomedicines
Several reproductive issues in both men and women are caused by changes in the pulsatile secretion of luteinizing hormone (LH) and follicle-stimulating hormone (FSH).

Advent of NK3R Antagonists for the Treatment of Menopausal Hot Flushes: A Narrative Review

BJOG: An International Journal of Obstetrics &Gynaecology, EarlyView.
ABSTRACT The menopause transition is marked by symptoms predominantly attributed to declining oestrogen levels. Approximately 80% of women experience associated symptoms, and 25% experience severe symptoms. The commonest are vasomotor symptoms (VMS), collectively referring to hot flushes and/or night sweats.

Testicular histopathology and its association with germ cell numbers, serum concentrations of reproductive hormones, and semen quality

Andrology, EarlyView.
Abstract Background It is well‐established that spermatogenesis, semen quality, and reproductive hormones are interlinked. It is, however, less well‐described how various specific testicular histopathologies are linked to reproductive hormones and semen quality.

A drop in serum estradiol levels during GnRH antagonist cotreatment in cycles stimulated with gonadotropins is associated with lower cumulative live birth rates

Frontiers in Endocrinology
Over the last decades, the gonadotropin-releasing hormone (GnRH) antagonist protocol has become widely used for prevention of premature luteinizing hormone surge during ovarian stimulation with exogenous gonadotropins.

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

Andrology, 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.

Identification of MEF2A, MEF2C, and MEF2D interactomes in basal and Fsk‐stimulated mouse MA‐10 Leydig cells

Andrology, EarlyView.
Abstract Background Myocyte enhancer factor 2 transcription factors regulate essential transcriptional programs in various cell types. The activity of myocyte enhancer factor 2 factors is modulated through interactions with cofactors, chromatin remodelers, and other regulatory proteins, which are dependent on cell context and physiological state.

Cryptorchidism: Novel genetic insights into CCDC149 mutations

Andrology, EarlyView.
Abstract Background Cryptorchidism, characterized by the failure of one or both testes to descend into the scrotum, is a common congenital condition that can lead to infertility and increased risk of testicular cancer. CCDC149, a coiled‐coil domain‐containing protein, has been implicated in various developmental processes, but its role in the male ...

Luteinizing hormone receptor knockout mouse: What has it taught us? [PDF]

Andrology
Abstract Luteinizing hormone (LH), along with its agonist choriongonadotropin (hCG) in humans, is the key hormone responsible for the tropic regulation of the gonadal function. LH and hCG act through their cognate receptor, the luteinizing hormone/choriongonadotropin receptor (LHCGR; more appropriately LHR in rodents lacking CG), located in the testis ...
