Reptile reproduction can be a confusing topic due to the variety of normal reproductive strategies found throughout different reptile species. Nevertheless it important to understand normal reproductive processes to correctly approach some commonly seen problems. The recording of this R.A.C.E.-approved, web-based seminar discusses normal reproductive strategies of reptiles, including important reproductive anatomy and physiology. Three clinically important conditions, pre-ovulatory or follicular stasis, post-ovulatory dystocia, and cloacal prolapse, are also explored in detail.
The guinea pig is a popular companion animal and a common research model. Guinea pigs are useful in reproductive studies because they share many reproductive traits with human beings. This article reviews anatomy and physiology of the guinea pig reproductive tract and summarizes some clinically significant medical problems.
Proper management of the pregnant sow requires an understanding of the risk factors associated with pregnancy-related disease and an ability to recognize early signs of problems. This client education handout explains proper care of the breeding and pregnant sow and provides tips for careful monitoring.

Dystocia is defined as the inability of a sow to deliver her litter normally. In breeding colonies, maternal mortality and loss of the pup is an important and common problem in the guinea pig. This review article discusses the pathogenesis of disease, gestation and parturition, important differential diagnoses, diagnostics, therapy, prognosis, neonatal care, and prevention. There is also a brief quiz to reinforce learning.
View a recording of this AAVSB R.A.C.E.-approved web-based seminar presented by Eric Klaphake, DVM, DACZM, DABVP (Avian Practice), DABVP (Reptile & Amphibian), then take the brief post-test to earn 1 hour of continuing education credit. This webinar explores five common reptile clinical presentations in detail: trauma, gastrointestinal foreign body, neurological deficits, respiratory difficulty, and reproductive problems.
Reproductive emergencies are most commonly seen in small psittacine birds like the cockatiel, lovebird and budgerigar parakeet. This article reviews conditions commonly seen on an emergency basis such as dystocia, egg yolk peritonitis, cloacal or oviductal prolapse, and/or chronic egg laying. Pertinent anatomy and physiology as well as case management, including the reproductive history, physical examination, diagnostic imaging, and behavioral modification techniques are also discussed.
Detecting a shelled egg on physical examination is not necessarily a problem—birds lay eggs everyday! However palpation of a shelled egg is an important clinical finding that can be associated with dystocia. The egg is shelled in a distal part of the oviduct called the uterus or shell gland. Therefore a shelled egg would normally be palpable in either the…
Common reproductive conditions of the reptile include prolapse of the cloaca, oviduct or copulatory organ, yolk coelomitis, dystocia or egg binding, as well as follicular stasis. This review article on twelve key facts explores clinically relevant anatomy and physiology and appropriate husbandry as well as key points of urgent care and general principles of case management.
Cloacal prolapse is a serious and potentially life-threatening problem. Prolapses can originate from the cloaca, oviduct or intestinal tract. The cloaca normally prolapses during egg laying or oviposition, and normal retraction of the cloaca may be slowed or absent in an obese hen or one with hypocalcemia. Excessive abdominal contractions caused by an abnormal egg, dystocia, cloacal disease, gastrointestinal disease or chronic mastubatory behavior can also promote prolapse.
