Summary In vitro production of embryos has gained prominence as a tool for use in wildlife conservation programmes in situ and ex situ. However, the development of this technique depends on steps that include ovarian stimulation, collection and oocyte maturation. The purpose of this study was to assess the feasibility of an ovarian stimulation protocol for follicular aspiration, the efficiency of videolaparoscopy for follicular aspiration and test a medium for in vitro oocyte maturation for the species Mazama gouazoubira. Five females were submitted to repeated ovarian stimulation (hormone protocol using controlled internal drug release), and estradiol benzoate on D0 and eight injections of follicle-stimulating hormone, once every 12 h, from D4 onwards at 30-day intervals. Fourteen surgical procedures were performed in superstimulated females, resulting in the collection of 94 oocytes and an average of 17.1 ± 9.1 follicles observed, 13.5 ± 6.6 follicles aspirated and 7.2 ± 3.7 oocytes collected per surgery. After collection, the oocytes were submitted to in vitro maturation for 24 h and stained with Hoechst 33342 dye to evaluate their nuclear status; 64.5% of the oocytes reached MII and 16.1% were spontaneously activated by parthenogenesis. The nuclear status of oocytes that did not undergo in vitro maturation was evaluated; 80.9% were found to be immature.

The Right

We present a very rare case of right-sided isolated pleural effusion in a patient with severe endometriosis who, in relation to in vitro fertilization (IVF), developed ovarian hyperstimulation syndrome (OHSS). Earlier laparotomy showed grade IV endometriosis including endometriotic implants of the diaphragm. The patient had no known risk factors for OHSS and only a moderate number of oocytes aspirated. She received, however, repeated hCG injections for luteal support. The patient did not achieve pregnancy but was hospitalized due to pain in the right side of the chest and dyspnoea. A chest computed tomography (CT) showed a pleural effusion on the right side. Total of 1000 ml of pleural fluid was drained after a single thoracentesis. After three days, the symptoms and fluid production ceased. Ascites is a common finding in OHSS, but pleural effusions are rare. Further, isolated pleural effusions have not previously been described in a patient with endometriosis. We suggest that the repeated hCG injections induced effusions from the endometriotic lesions at the diaphragm and as a consequence this patient developed isolated hydrothorax.

Background: Complications associated with oocyte retrieval include ovarian hyperstimulation syndrome, ovarian torsion, infection, bleeding, and even acute urinary retention. Case: A 29 year old female presented to the emergency department for dizziness and syncope following oocyte retrieval and was admitted for ovarian hyperstimulation syndrome. Her urinary catheter was obstructed by blood clots and relieved with bladder irrigated. The catheter was removed after twenty-four hours, and she was able to void spontaneously. Four days after discharge, she returned for urinary retention. She underwent cystoscopy and 10cc of blood clots was evacuated. The bladder appeared normal without intravesicular bleeding, and she was discharged home. Twelve hours later, the patient returned for urinary retention. Another cystoscopy was performed and 150cc of blood clots was evacuation. Her symptoms resolved. Conclusion: Hematuria and urinary retention are rare but serious complications of oocyte retrieval. Management options include a urinary catheter, bladder irrigation, urologic imaging, and cystoscopy
