RESUMEN
PURPOSE: What are the reproductive outcomes of women who had fertility preservation (FP) using either oocyte or embryo vitrification after fertility-sparing surgery (FSS) for a borderline ovarian tumor (BOT)? METHODS: A retrospective, single-center cohort study was conducted between January 2013 and December 2021. Patients with BOT who resorted to FP by vitrifying oocytes or embryos were included. Both clinical and reproductive parameters were reviewed. The primary outcome was live birth. RESULTS: In total, thirteen patients who performed 31 FP cycles were included. Of those, six patients achieved eight live births after a mean follow-up period of 79 months. Three further pregnancies are still ongoing. All pregnancies/live births were obtained without using their cryopreserved oocytes or embryos. CONCLUSION: Women who had FSS for BOT have favorable prospects of live offspring, even without the need to use their cryopreserved material. Fertility preservation in patients with BOT has to be considered as a tool to mitigate the risk of infertility that may arise in case of BOT recurrence requiring castrating surgery.

Goldfish (Carassius auratus) were fitted with intracranial stainless steel microelectrodes for electrical evocation of behavioural arousal and its cardiac and ventilatory correlates. Behaviour was monitored on a videosystem and ECG electrodes and a buccal catheter were implanted to monitor physiological responses. Thresholds for responses were described in relation to the current spread likely to excite CNS tissue. Two types of responses were obtained. These were (A) cardiac and ventilatory responses alone, apparently due to stimulation of primary sensory pathways and (B) these responses and behavioural arousal responses which were elicited at higher thresholds. These latter, more complete expressions of arousal resulted from stimulation of the Dm/Dc region of the telencephalon, the dorsal diencephalon and the midbrain tegmentum. Response thresholds were higher and physiological response magnitudes lower in the midbrain tegmentum compared to the forebrain regions.
