Objective—To determine an efficient method for the collection of semen samples by means of electroejaculation, characterize spermatozoa quality and quantity, and determine the effect of refrigerated storage on motility of spermatozoa obtained from green iguanas (Iguana iguana).

Animals—18 adult green iguanas.

Procedures—Green iguanas were anesthetized, and semen samples were obtained by means of electroejaculation. Up to 3 series of electrostimulations were performed; the procedure was stopped after a semen sample was obtained. Various semen sample variables were evaluated.

Results—Semen samples were obtained from 16 iguanas; most (n = 10) iguanas produced a semen sample after the second series of electrostimulations. Median semen sample volume was 0.05 mL. Mean spermatozoa concentration was 2 69.0 × 106 spermatozoa/mL. Median percentage of motile spermatozoa was 78%. The only morphological abnormality of spermatozoa was bent tails (mean percentage in a semen sample, 5.7%). Spermatozoa motility decreased significantly during refrigeration (4°C); median percentage motility after 24, 48, and 72 hours of refrigeration was 60%, 33%, and 0%, respectively.

Conclusions and Clinical Relevance—Results of this study suggested electroejaculation can be performed to collect semen samples from green iguanas, characteristics of iguana semen samples are similar to those for semen samples obtained from other reptiles, and motility of iguana spermatozoa decreases during refrigeration within 48 to 72 hours.

Bleeding as a result of trauma, hemorrhagic diseases, or primary platelet-related abnormalities is a major cause of morbidity and mortality in humans and animals. 1–5 In humans, for example, hemorrhage is the most common cause of preventable death following traumatic injury in patients < 65 years of age and is a leading cause of potentially survivable deaths during military operations. 1,3,6 Treatment for hemorrhage, in addition to supportive care and volume resuscitation, frequently includes IV administration of whole blood or platelet concentrates to counteract the effects of a rapid decrease in platelet numbers associated with platelet consumption and
