The chemistry of the Body

Surgical castration involves the permanent removal of the testes and was the most common method in the past, usually as punishment. It is still used today in the traditional neutering of pets to prevent overpopulation. In some countries, such as the Czech Republic and Germany, a testicular pulpectomy is performed, in which part of the testes are removed, without obvious disfigurement, and testosterone production is greatly reduced but not eliminated.50 Such castration is, clearly, irreversible.

For many years, researchers have looked for an alternative neutering/contraceptive method for animals, especially stray dog and cats. A single intratesticular injection that could cause the interruption of spermatogenesis would be particularly interesting for its simplicity and speed, as it could be applied to many animals in a single day without the need for specific equipment or environment. In general, zinc gluconate and calcium chloride, the most used substances for chemical castration by intratesticular injection, cause atrophy in the seminiferous tubules, disruption in spermatogenesis, fibrosis and calcification of testicular parenchyma and reduction of testicular volume, together with reduced sperm motility and low sperm count or azoospermia, leading to subfertility or infertility in male animals (Fagundes et al. 2014; Vannucchi et al. 2015; Silva et al. 2018; Leoci et al. 2019; Rafatmah, Mogheiseh, and Eshghi 2019). However, many studies report side effects in the treated animals, such as swelling, inflammation, pain, hemorrhage, necrosis and scrotal ulcerations (Levy et al. 2008; Oliveira et al. 2013; Forzán et al. 2014; Rafatmah, Mogheiseh, and Eshghi 2019). In this sense, researches are still needed to optimize these methods or find new approaches to impair male animal reproduction.
Compounded bioidentical menopausal hormone therapy – a physician perspective
Published in Climacteric, 2021
Package labeling for some cutaneous FDA-approved estradiol and testosterone preparations has cautioned about the possibility of inadvertent transfer to small children and pets, and provided guidance to minimize this occurrence. Case reports highlight examples of transfer of cutaneous estradiol products (predominantly, cBHT creams) from adults to small children54–56 and pets57–60. Complications include delays in the correct diagnosis when evaluating signs of gynecomastia in children and unnecessary and costly diagnostic procedures to evaluate sexual development (nipple and vulvar enlargement) in animals, especially after neutering.

A team of FVM veterinarians offered advice to the MHW team on dog selection and helped develop a health care plan. Preventative health care included vaccinations and parasite control tailored to the dog’s needs (Canadian Parasitology Expert Panel, n.d.; Ford et al., 2017). Risks were assessed based on the dog’s habitat and lifestyle. Neutering was performed at 8.5 months as per the current recommendations for Australian Labradoodles (Hart et al., 2020). Students at the FVM provided preventative healthcare for the dog, under faculty supervision, as a learning experience, including a commitment to manage the dog’s wellness needs.
