Key Findings
- No significant change in testis size after 6 weeks
- Endocrine response to hCG stimulation unchanged
- Histology showed normal spermatogenesis
Practical Outcomes
- For biohackers looking to suppress male fertility with a GnRH implant, this goat study suggests the approach may not work, at least in the short term. It provides no actionable protocol for humans and highlights the need for more species‑relevant research before trying similar methods.
Summary
A slow‑release GnRH implant (deslorelin) was put into a healthy adult male goat, but after six weeks it didn’t shrink the testicles, didn’t change hormone responses, and sperm production stayed normal, meaning the goat stayed fertile.
Abstract
A 9.4 mg deslorelin slow-release implant was inserted into an adult, healthy billy goat to achieve temporary infertility and a reduction in sexual behavior. The implant was inserted in late autumn. No significant change in testis size was observed over the following 6 weeks. The endocrine function of the testis, which was examined by stimulation with human chorionic gonadotropin, was also unchanged after 6 weeks compared to the initial examination. Histological examination revealed a preserved spermatogenesis.In conclusion, the application of a GnRH analogue implant in the adult male goat has no influence on the investigated parameters - and thus probably also on its fertility.
