INSL3 Expression in Leydig Cells is a Biomarker for Immunocastration in Boars: Transcriptional Evidence. [PDF]

open access: yesAndrology
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 ...

Wiederaufnahme der Hodenfunktion bei Ebern nach Immunisierung gegen das Go-nadotropin Releasing Hormon (GnRH) mit dem kommerziellen Antigen IMPROVAC® [PDF]

open access: yes, 2012
Traditionally, male pigs are surgically castrated without anaesthesia to avoid later occurrence of the sex odour androstenone in the carcass.Active immunization against GnRH is a painless alternative which inhibits LH and thus steroidogenesis in the Leydig cells.Time between second vaccination and return of Leydig cell function is unknown.

Effects of an anti-gonadoliberin releasing hormone vaccine on testicular, epididymal and spermatogenic development in the horse. [PDF]

open access: yesReprod Domest Anim, 2022
Abstract The effects of the GnRH vaccine Improvac® on testicular and epididymal morphometrics, histology and spermatogenesis were measured in 19 young (15–20 months) colts randomly assigned to one control (saline, castration at 57 days, n = 6) or either of two GnRH vaccine‐treatment groups, T‐57 (castration at 57 days, n = 7) or T‐100 (castration at ...

Advances in the ultrasound diagnosis in equine reproductive medicine: New approaches. [PDF]

open access: yesReprod Domest Anim, 2022
Abstract Ultrasound technology has led to new lines of research in equine reproduction, and it has helped to greatly improve clinical diagnosis and reproductive outcomes in equine practice. This review aims to discuss the potential clinical uses and new approaches of ultrasonography in equine reproduction.

The effectiveness of Imrovac® in industrial pork production

open access: yesTheoretical and Applied Veterinary Medicine, 2021
The clinical efficacy of the use of immunobiological castration was studied in comparison with boars in which orchidectomy was performed by open method «on a ligature», as well as in non-castrated animals.

Effects of immunocastration and supplementary feeding level on the performance and blood biochemical markers of farmed yearling fallow deer (Dama dama)

open access: yesJournal of Animal Physiology and Animal Nutrition, Volume 107, Issue 5, Page 1158-1166, September 2023., 2023
Abstract In cervids, blood biochemical markers may reflect changes in various physiological and environmental factors, especially in response to changes in metabolism following nutrient supplementation or the manipulation of hormone production. Decreasing androgen production through immunocastration (IC) to ease the husbandry of male animals is ...

Immunocastration in adult boars as a model for late‐onset hypogonadism

open access: yesAndrology, Volume 10, Issue 6, Page 1217-1232, September 2022., 2022
Abstract Background While immunocastration has been studied in male pre‐pubertal pigs, data on older, sexually mature animals are limited. To understand the physiological effects of androgen deprivation in the late sexual development phase, we compared mature immunocastrated boars (n = 19; average age = 480 days) to young male immunocastrated pigs (n =

Suppression of reproductive behaviour and gonadal function in female horses—An update

open access: yesReproduction in Domestic Animals, Volume 57, Issue S4, Page 4-12, September 2022., 2022
Abstract The behaviour of mares is often detrimental to their performance resulting in frequent demand for methods to suppress gonadal function. In addition, prevention of unintended reproduction especially in feral horse populations may require methods for suppression of gonadal function.
