Abstract
Objectives: Our review aimed to consolidate the latest update on the application of in
vitro maturation among immature oocyte harvest in combination with ovarian
tissue cryopreservation known as ovarian tissue oocyte–in vitro
maturation. Methods: A thorough search for relevant studies was conducted via PubMed, Google
Scholar, EMBASE, and clinical.gov databases up to December 2020. The primary
outcome was the oocyte maturation rate, which measured the number of
immature oocytes (geminal vesicle stage) that progressed to mature oocytes
(meiosis II stage) following in vitro maturation. The secondary outcomes
were the fertilization rate following intracytoplasmic sperm injection/in
vitro fertilization of these oocytes for the embryo cryopreservation cohort.
Our review included pre-pubertal girls and women with cancer who underwent
ovarian tissue oocyte–in vitro maturation as fertility preservation. Results: The primary search identified 207 studies. Twelve manuscripts were selected
for inclusion in our review following duplication assessment, title and
abstract screening, and full-text evaluation tailored to our inclusion
criteria. All the population belonged to a cancer group and underwent
concurrent ovarian tissue oocyte–in vitro maturation. A total of 5724
immature oocytes were obtained following ovarian tissue cryopreservation.
Approximately 33.84% of the immature oocytes successfully matured via in
vitro maturation, which were cryopreserved as oocytes or fertilized as
embryos and subsequently stored for future use. Conclusion: Our review proposed the potential application of ovarian tissue oocyte–in
vitro maturation in increasing the number of mature oocytes. The acceptable
improvement in oocyte maturation rate following in vitro maturation
indicates that improving oocyte outcomes is an excellent cost-effective
strategy for fertility preservation among women with cancer.

Abstract
While the interactions of the gut microbiome and blood metabolome have been widely studied in polycystic ovary disease in women, follicular cysts of ewes have been scarcely investigated using these methods. In this study, the fecal microbiome and serum metabolome were used to compare between ewes diagnosed with ovarian cystic follicles and ewes with normal follicles, to investigate alterations of the fecal bacterial community composition and metabolic parameters in relation to follicular cystogenesis. Ewes from the same feeding and management system were diagnosed with a follicular cyst (n = 6) or confirmed to have normal follicles (n = 6) by using a B-mode ultrasound scanner. Blood serum and fresh fecal samples of all ewes were collected and analyzed. The α-diversity of fecal microbiome did not differ significantly between follicular cyst ewes and normal follicle ewes. Three genera (Bacteroides, Anaerosporobacter, and Angelakisella) were identified and their balance differentiated between follicular cyst and normal follicle ewes. Alterations of several serum metabolite concentrations, belonging to lipids and lipid-like molecules, organic acids and derivatives, organic oxygen compounds, benzenoids, phenylpropanoids and polyketides, and organoheterocyclic compounds, were associated with the presence of a follicular cyst. Correlation analysis between fecal bacterial communities and serum metabolites indicated a positive correlation between Anaerosporobacter and several fatty acids, and a negative correlation between Bacteroides and L-proline. These observations provide new insights for the complex interactions of the gut microbiota and the host serum lipid profiles, and support gut microbiota as a potential strategy to treat and prevent follicular cysts in sheep.

Abstract
The development of new bioactive molecules based on the molecular hybridization has been widely explored. In line with this, reliable tests should be employed to give information about the toxicology of these new molecules. In this sense, the use of in vitro tests is a valuable tool, especially the in vitro maturation of oocytes (IVM), which is an efficient resource to discover the potential toxicity of synthetic molecules. Thus, the aim of the present study was to evaluate the toxicological effects of the selenium-containing indolyl compound 3-(4-Chlorophenylselanyl)-1-methyl-1H-indole (CMI), on different quality parameters of bovine oocytes through the IVM. Different concentrations of the CMI compound (0, 25, 50, 100, 200 μM) were supplemented during the in vitro maturation process. After, the oocyte maturation rate, glutathione (GSH) levels, reactive oxygen species (ROS) levels, membrane, and mitochondrial integrity were evaluated. The results showed that the lowest concentration of CMI induced the highest GSH production (P < 0.05), an important marker of cytoplasmic quality and maturation. All treatments increased ROS production in relation to non-supplementation (P < 0.05). In addition, oocyte maturation was reduced only with the highest concentration of CMI (P < 0.05). Supplementation with CMI did not impact mitochondrial activity, integrity and cell membrane. To our knowledge, this is the first study that evaluates CMI on the oocyte in vitro maturation process. Importantly, our results did not find any toxic effect of CMI on bovine oocytes. CMI was efficient for cytoplasmic maturation by promoting an increase in the intracellular levels of glutathione.

Abstract
The efficiency of oocyte in-vitro maturation (IVM) and vitrification procedures after ex-vivo collection from ovarian tissue were assessed according to patient age, number of retrieved oocytes and tissue transport conditions. The combined procedure was performed in 136 patients: 130 adults (mean 27.6 ± 5.6 years) and six prepubertal girls (mean 8.7 ± 2.3 years). A higher mean number of oocytes were collected in girls compared with adults (11.5 ± 8.0 versus 3.8 ± 4.2, respectively, P < 0.001) but the percentage of degenerated oocytes was significantly higher in girls (35.5% versus 17.1%, respectively, P < 0.001). IVM rates were significantly lower in prepubertal than postpubertal population (10.3% versus 28.1%, P = 0.002). In adults, a negative correlation was observed between number of retrieved oocytes and age (P = 0.002; r = -0.271); the correlation was positive between anti-Müllerian hormone (AMH) and number of collected oocytes (P = 0.002; r = 0.264). IVM rates were not correlated with AMH levels (r = 0.06) or age (r = -0.033). At present, nine oocytes and one embryo have been warmed in four patients and one biochemical pregnancy obtained. This suggests the combined procedure could be an additional option for fertility preservation.

Abstract
We compare protocols for the short-term preservation of collared peccarie's ovarian preantral follicles (PFs) by using phosphate buffered saline- (PBS) or powdered coconut water- (ACP(r)) based medium. For morphology analysis each pair of ovaries collected from six females was divided into nine fragments. One fragment was destined for morphology analysis (histology and transmission electron microscopy - TEM), constituting the control group and the other fragments were placed in tubes with PBS or ACP(r), packed in 5 L Styrofoam boxes, stored for 4h, 12h, 24h, and 36h, and then analyzed. For viability analysis a pair of ovaries from two additional females was divided into nine fragments; one fragment was immediately destined for viability analysis (Trypan blue test) and the other fragments were stored as previously described, until 24h and then analyzed. After 4h storage in ACP(r) medium, the follicular integrity was similar to control (87.8% vs 94.4%, respectively); however, ultrastructural analyses revealed swollen mitochondria as the first signals of PF degeneration. It was observed that ACP(r) (66.7%) was more efficient than PBS (49.4%) to preserve the morphological integrity after 36h storage (P<0.05); however, no differences were observed on follicular viability (P>0.05). In conclusion, the use of the ACP(r) is recommended for the short-term preservation of Pecari tajacupreantral follicles.

Abstract
The objective of this study was to determine the influence of powdered coconut water (ACP-318(®)) diluted in high glucose (11.0 mM) TCM199 in the achievement of nuclear in vitro maturation (IVM) of canine oocytes. Cumulus oocyte complexes (COCs) (n = 632) were randomly allocated into three experimental groups named as group 1 (control group), group 2 (5% powdered coconut water) and group 3 (10% powdered coconut water). The percentage of meiotic resumption (MR) (GVBD to MII) was 39.1% (81/207), 50.2% (108/215) and 46.6% (98/210) for groups 1, 2 and 3 respectively (p < 0.05). There were no differences in MR rates among groups 2 and 3. The medium with ACP-318(®) slightly enhanced the nuclear maturation of canine oocytes when a comparison was established with rates of maturation exhibited by oocytes in the experimental group 1 without ACP-318(®) (p < 0.05). The results suggest that oocytes' nuclear morphology integrity and meiosis achievement were positively influenced when exposed to high glucose TCM199 supplemented with 5% powdered coconut water. Further investigation must be performed for a better understanding of powdered coconut water influence in cellular events during IVM of dog oocytes.

Abstract
Preantral follicles (PFs) form a far larger oocyte reservoir (~90% of the follicular population) than antral follicles. Several laboratories have focussed efforts on cryopreservation and in vitro culture (IVC) of PFs to obtain large numbers of fertilisable oocytes. This technology could be used to improve the reproductive potential of economically important animals, including goats, to preserve endangered species and breeds and improve fertility after chemotherapy in young women. Caprine PFs have been successfully cryopreserved using either vitrification or slow freezing. In addition, in vitro embryo production from oocytes enclosed in caprine PFs grown and matured in vitro was also achieved. The present paper selectively reviews the published studies on cryopreservation and IVC of caprine PFs to highlight advances, limitations and prospects.

Abstract
Ovarian cortical fragments from five adult ewes were in vitro cultured for 1, 3 or 5 days in the presence of minimum essential medium either supplemented or not by follicle-stimulating hormone (FSH) (100 ng/ml) or indole-3-acetic acid (IAA) (10, 20, 40 or 100 ng/ml), alone or in combination. After in vitro culture, ovarian fragments were submitted to follicular isolation and viability test was performed using trypan blue. Addition of IAA (10 ng/ml) to a free-FSH medium resulted in the highest percentages of viable follicles, but was progressively deleterious in higher concentrations (20, 40 and 100 ng/ml) if in absence of FSH. Follicular development was observed only when FSH was added to an IAA-free medium. In conclusion, IAA at a concentration of 10 ng/ml increases follicular survival in vitro. However, at high concentrations (20, 40 or 100 ng/ml), this auxin may be deleterious to preantral follicles, the addition of FSH to the medium being necessary.

Abstract
The use of the large pool of preantral follicles is a promising alternative to provide high numbers of fertilizable oocytes to reproductive biotechnology. This issue is particularly important to canids, since current rates of success of in vitro techniques using oocytes are very limited, and many species within this family are threatened by extinction. The aim of this study was to evaluate effects of temperature, medium and time on morphology and viability of canine preantral follicles during short-term preservation. Canine ovaries were cut into fragments which were incubated in 0.9% NaCl solution or in minimum essential medium (MEM) at 4, 20 or 38 degrees C for 2, 6, 12 or 24 h. Afterwards, preantral follicles were analyzed by histology, transmission electron microscopy and viability testing using trypan blue, calcein-AM and ethidium homodimer-1. Percentages of morphological normal and viable follicles were maintained similar to control (time 0 h) after incubation in 0.9% NaCl at 4 or 20 degrees C for up to 6h and at 38 degrees C for 2 h. Using MEM, such preservation was possible for 12h at 4 or 20 degrees C, and for 6h at 38 degrees C. These results indicate that preservation of canine preantral follicles might be better accomplished through hypothermic (4 or 20 degrees C) storage in MEM, which ensures maintenance of morphology and viability for up to 12h.

Abstract
Investigou-se a eficiência da solução salina 0,9% (SS) e TCM 199 na conservação de folículos pré-antrais (FOPA) bovinos in situ em diferentes temperaturas e tempos de incubação. Cada par ovariano foi dividido em 25 fragmentos. Um fragmento foi escolhido aleatoriamente e fixado imediatamente após a coleta (controle). Os demais foram distribuídos em tubos contendo SS ou TCM 199 a 4, 20 ou 39ºC por 2, 4, 12 ou 24h. A análise histológica mostrou que a conservação a 4ºC em ambas as soluções manteve a porcentagem de FOPA normais similar ao controle. A conservação em SS a 20ºC por 12 ou 24h, TCM 199 a 20ºC por 24h e em ambas as soluções a 39ºC a partir de 2h aumentou (P<0,05) a porcentagem de FOPA degenerados comparada à porcentagem de folículos-controle. Em ambas as soluções, independente do tempo de incubação, a porcentagem de folículos normais, após conservação a 39ºC, foi (P<0,05) menor que a obtida com 4 e 20ºC. FOPA bovinos podem ser conservados eficientemente a 4ºC por até 24h em ambas as soluções, e a 20ºC por 4 e 12h em SS e TCM 199, respectivamente.

Abstract
Oocytes lose their developmental competence during prolonged storage of the ovary. In the present study, we supplemented the preservation solution for pig ovaries (phosphate buffered saline, PBS) with glucose and preserved the ovaries for 6 h at 25 C. Subsequently, we examined the glucose concentration of the follicular fluid (FF), pH of the FF, survival rate of the granulosa cells, and maturation and developmental competence of oocytes after storage. During storage, the glucose concentration of the FF (2.1 mM), pH of the FF (7.4), and survival rate of the granulosa cells (69.5%) rapidly decreased (glucose concentration: under 1.1 mM; pH: 6.8; and survival rate: 43%). On the other hand, when the preservation solution was supplemented with glucose (15 mM), the glucose concentration of the FF increased and the survival rate of the granulosa cells improved, although the pH of the FF decreased further (from 6.8 to 6.6). In addition, supplementation with glucose significantly improved the rates of oocytes at metaphase II (0 h: 65.0%; 6 h without glucose: 23.8%; and 6 h with glucose: 43.8%) and attenuated the decline in the rates of fertilization and development that resulted from prolonged storage, although there were no significant differences. In conclusion, modification of the preservation solution by the addition of glucose increased the glucose concentration of the FF and improved the rate of maturation of pig oocytes.

Abstract
Avaliou-se o desenvolvimento de folículos pré-antrais ovinos após o cultivo in vitro do córtex ovariano em várias concentrações de ácido 3-indol acético (IAA). O córtex ovariano foi dividido em fragmentos de aproximadamente 3×3mm. Um fragmento foi imediatamente fixado em Bouin (controle - dia 0) e os demais destinados ao cultivo por dois ou seis dias em meio essencial mínimo (MEM+) acrescido de 10, 40, 100, 500 ou 1000ng/ml de IAA. Após o cultivo in vitro, não houve variação entre folículos dos tratamentos e folículos-controle, exceto nos suplementados com 40ng/ml de IAA. Nestes observaram-se redução de folículos primordiais e aumento de folículos em desenvolvimento (P<0,05). Em relação aos folículos do grupo-controle, houve redução de pré-antrais normais no cultivo de seis dias (P<0,05). Após dois dias de cultivo, a redução foi observada somente nos folículos suplementados com 500 ou 1000ng/ml de IAA. Folículos pré-antrais ovinos podem ser ativados in vitro com sucesso após o cultivo em MEM+ suplementado com 40ng/ml de IAA.

Abstract
The objective was to determine the morphological and ultrastructural features of sheep primordial follicles preserved in either 0.9% saline solution or TCM 199 at different temperatures. Soon after death, the ovarian pair of each ewe (n = 5) was divided into 25 fragments. One fragment was immediately fixed for morphological evaluation (control). The other 24 fragments were randomly distributed in tubes containing 2 ml of 0.9% saline solution or TCM 199 and maintained at 4, 20 or 39 degrees C for 2, 4, 12, or 24h. Based on histological assessment, storage of ovarian fragments in 0.9% saline solution at 20 degrees C for up to 24h and in both solutions at 39 degrees C for 4, 12 or 24h increased (P < 0.01) the percentage of degenerate primordial follicles compared with controls. In contrast, preservation at 4 degrees C in both solutions, kept the percentage of morphologically normal primordial follicles similar to control values. Although histological integrity of primordial follicles was maintained in fragments stored at 20 degrees C for up to 24h in TCM 199, these results were not confirmed by ultrastructural analysis. Based on transmission electron microscopy, only primordial follicles stored at 4 degrees C for up to 24h, at 20 degrees C for up to 12h and at 39 degrees C for up to 2h in both solutions were ultrastructurally normal. In conclusion, sheep primordial follicles were successfully preserved at 4 degrees C for up to 24h, at 20 degrees C for up to 12h and at 39 degrees C for 2h in 0.9% saline solution or TCM 199.

Abstract
The maintenance of follicle quality during the transportation of ovaries is essential for the successful cryopreservation and in vitro development of preantral follicles. The objective of this study was to evaluate the effect of cooling ovarian tissue on the conservation of zebu cow preantral follicles. Ovarian pieces were immersed in saline or coconut water (CW) solutions and maintained at 4 or 20 degrees C for 6, 12, or 18 h. Preantral follicles were evaluated by histology and transmission electron microscopy. Storage of ovarian pieces at 20 degrees C for 12 or 18 h significantly reduced the percentage of morphologically normal follicles compared to controls. In contrast, conservation at 4 degrees C for up to 18 h and at 20 degrees C for up to 6 h kept the percentage of normal follicles similar to controls. However, the type of solution that the ovaries were immersed in had little effect on the results. Decreased cellular metabolism probably accounted for better preservation of preantral follicles at 4 degrees C. In conclusion, zebu cow ovaries were successfully stored at 4 degrees C for up to 18 h with no morphological damage to preantral follicles. However, at 20 degrees C, ovaries could only be stored for 6 h.
