[Experimental study of electro-ejaculation in the baboon (author's transl)]

Area of Science:

• Reproductive medicine
• Neuro-urology
• Animal models in research

Background:

• Electro-ejaculation is a method for obtaining semen samples.
• Paraplegia can lead to ejaculatory dysfunction, impacting fertility.
• Developing effective assistive reproductive technologies is crucial for affected individuals.

Purpose of the Study:

• To adapt and evaluate an electro-ejaculation apparatus for use in paraplegic males.
• To assess the safety and efficacy of intra-rectal electrode stimulation for semen retrieval.
• To determine the potential of this technique for improving procreation in paraplegic men.

Main Methods:

• Development of a specialized apparatus for intra-rectal electrode stimulation.
• Performance of 27 electro-ejaculations on 9 paraplegic monkeys.
• Evaluation of semen parameters (volume, motility, sperm count) and assessment for complications.

Main Results:

• 22 out of 27 electro-ejaculations were successful, with 3 yielding only coagulum.
• Semen quality, including sperm motility and count, was reduced compared to normal ejaculation but deemed utilizable.
• No complications or lesions were observed during animal observation, rectoscopy, or histological examination.

Conclusions:

• The developed apparatus and technique are safe and applicable for semen retrieval in paraplegic males.
• Electro-ejaculation shows potential to enhance fertility and procreation possibilities for paraplegic individuals.
• Further refinement of the technique may improve semen quality and success rates.
