Objective: To describe the anatomy, morphology and physiology of the reproductive system of male jaguars, as well as assisted reproduction techniques. Methodology: A literature review on the anatomy and morphology of the jaguar´s reproductive system, its physiological characteristics and assisted reproduction techniques were carried out to document relevant information on the topic. Results: With this review, basic aspects of the morphology of the reproductive system of the jaguars are disclosed, although scarce knowledge is available on their reproduction. The advances in the collection, evaluation and cryopreservation of semen of this feline are shown, in addition to assisted reproduction techniques such as artificial insemination and in vitro fertilization, which have a great potential to safeguard the species. Study limitations: The jaguar, an emblematic species of Latinamerica, is an endangered species, like other wild felids species as ocelot (Leopardus pardalis) and margay (Leopardus wiedii), which makes it necessary to have a national assisted reproduction program. However, for this to be possible, information about their reproductive physiology is necessary, which is complicated in wild animals and even more so because the reproductive mechanisms greatly differ between felids species. There is scarce information in this regard from its free-living or Mexican zoos, it is for this reason necessary to generate such information. Conclusions: It is necessary to continue working on designing protocols for artificial insemination and other assisted reproduction techniques such as in-vitro fertilization specifically for male Panthera onca.

Involuntary childlessness is a well-known phenomenon, and in Denmark, every twelfth child is born through the use of assisted reproduction. Denmark is currently positioned as one of the key global actors both as far as the use of in-vitro ­fertilization (IVF) is concerned as well as within the global ­market in sperm and reproductive technologies. In this article, the authors develop a feminist legal rhetorical framework to discuss how the Danish law and ethical guidelines on adoption and assisted reproduction rhetorically produce different master plots on “natural,” “artificial,” and “monstrous” forms of kinship. The authors conclude with a discussion of the potential that a feminist legal rhetorical framework holds, including its ability to analyze how rhetorical figures and metaphors legitimize certain types of kinship as well as the ability to raise new and provo­cative questions related to gender equality within the law

Abstract Ovarian hyperstimulation syndrome (OHSS) remains one of the most life-threatening and potentially fatal complications of assisted reproduction treatments, arising from excessive stimulation of the ovaries by exogenous gonadotropins administrated during in vitro fertilization procedures, which is characterized by massive fluid shift and accumulation in the peritoneal cavity and other organs, including the lungs and the reproductive tract. The pathogenesis of OHSS remains obscure, and no definitive treatments are currently available. Using RT-PCR, Western blot, and electrophysiological techniques we show that cystic fibrosis transmembrane conductance regulator (CFTR), a cAMP-activated chloride channel expressed in many epithelia, is involved in the pathogenesis of OHSS. Upon ovarian hyperstimulation, rats develop OHSS symptoms, with up-regulated CFTR expression and enhanced CFTR channel activity, which can also be mimicked by administration of estrogen, but not progesterone, alone in ovariectomized rats. Administration of progesterone that suppresses CFTR expression or antiserum against CFTR to OHSS animals results in alleviation of the symptoms. Furthermore, ovarian hyperstimulation does not induce detectable OHSS symptoms in CFTR mutant mice. These findings confirm a critical role of CFTR in the pathogenesis of OHSS and may provide grounds for better assisted reproduction treatment strategy to reduce the risk of OHSS and improve in vitro fertilization outcome.

This article explores the significance of the womb as an organizing principle for relatedness in Vietnam. It argues that contemporary individual and collective responses to in vitro fertilization bring into sharp relief the enduring importance of gestation and the mother-child bond for kinship formation. The author traces the womb as a site for determining maternal relatedness in contemporary assisted reproduction policy through cultural beliefs about gestation, popular legend, and contemporary and historical forms of polygamy and surrogacy, drawing attention to the continuities between past and current practices surrounding infertility and indigenous solutions to the challenges infertility poses in forming kin-relatedness.
