The clinical usefulness of plasma LH and FSH radioimmunoassays, both in basal and dynamic conditions, is briefly discussed. While occasional LH and FSH determinations may indicate only a serious gonad failure, at least when high values are found, dynamic studies before and after LH-RH i.v. injection may suggest a hypothalamic or pituitary lesion.

INSL3 Expression in Leydig Cells is a Biomarker for Immunocastration in Boars: Transcriptional Evidence

Andrology, EarlyView.
ABSTRACT Background Study aimed to obtain insights into physiological responses to immunocastration in pubertal boars by evaluating effects of alternative vaccination protocols and identifying a reliable immunocastration biomarker. Objectives It was hypothesized that the timing of gonadotropin‐releasing hormone (GnRH) suppression by immunocastration ...

Healthy Aging Men Do Not Suffer From Relevant Limitations of Their Reproductive Functions

Andrology, EarlyView.
Abstract Background While metabolic disorders are well‐established contributors to testosterone decline and erectile dysfunction (ED), little is known about the natural progression of reproductive parameters in healthy aging men. Objectives This study aimed to evaluate longitudinal changes in reproductive parameters and sought to determine the ...

Sperm Telomere Interactions Are Impaired in Testicular Cancer Before and After Adjuvant Therapy

Andrology, EarlyView.
ABSTRACT Background No study has yet explored telomere length or interaction in sperm nuclei of testicular cancer (TC) patients exposed to chemotherapy or radiotherapy. However, sperm telomere dynamics have emerged as a potential marker in male infertility.
