This reproductive tactic is an obligatory feature of male rattlesnakes’ reproductive cycle due to asynchrony between spermatogenesis and mating. Given that the ductus deferens is the primary site of sperm storage in male snakes, we aimed to investigate the morphological and histochemical changes in the distal ductus deferens of <em>C. durissus</em> throughout its reproductive cycle. In this species, spermatogenesis begins in spring and peaks in summer, while testes regress during autumn and winter. The distal ductus deferens of 28 mature male specimens was evaluated using histomorphometric and histochemical methods. Spermatozoa were consistently observed within the lumen of the ductus deferens in almost all specimens. The principal cells of the distal region of ductus deferens reacted positively for Periodic Acid-Schiff and Bromophenol Blue. Secretions were observed in the apical region of the principal cells' cytoplasm and along the epithelium edge, which may be related to gamete maintenance. Increased secretory activity of the principal cells was observed during periods of testicular activity. A reduction in the lumen of ductus deferens occurs during testicular regression, indicating possible fluid resorption by epithelial cells. Fluid resorption might be one of the mechanisms to ensure stored sperm viability, as it provides an increase in the glycoprotein’s concentration.</div></div>","PeriodicalId":75220,"journal":{"name":"Theriogenology wild","volume":"5 ","pages":"Article 100114"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142529773","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We incubated eggs and monitored embryonic development of <em>K. scorpioides</em> through egg candling. Fertile eggs were incubated, and candling analyses were performed weekly. Embryonic development in the early stages (first third of incubation) presented the following characteristics: presence of the vitelline circulatory system, expansion of this system, and descent of the embryo onto the yolk. Then, in the middle stages (second third of incubation), the intense pigmentation of the embryo was observed, with the body moving to prone position. Subsequently, in the late stages, the embryo grew, filling a large part of the internal space of the egg. The incubation period took on average 116.50 ± 13.11 days.

Unfortunately, the difficulty of accessing a significant number of animals under suitable physiological conditions hampers the advancement of these technologies. Pharmacological semen collection in jaguars is effective in acquiring a sufficient amount of sperm. However, the outcomes of artificial insemination (AI) and in vitro fertilization operations are impacted by poor sperm quality and limited freezability of the cells. Hormonal stimulation with eCG and hCG may be used to collect oocytes in jaguars; however, proximity to males influences ovarian response to exogenous hormones. Thus, the non-copulatory ovulation stimuli pattern must be considered in AI and laparoscopic ovum pick-up protocols in this species. Somatic cells may be an alternative for biobanks since they are easier to collect and transport and can be obtained from any age, sex, or origin of an animal, including post-mortem samples. Our research group recently succeeded in cultivating cells from three jaguars that were found dead on highways, demonstrating that cultivation is effective even in degenerating tissues.

In experiment 1, twenty ejaculates from 11 bulls were analyzed for percentages (%) of sperm motility (%MOT), viability (%VIA), and activities of SOD and GPx.
