“…However, after 48 h of in vitro culture, only the ovarian tissue cryopreserved with DMSO and FCS maintained a percentage of viable follicles similar to the cultured control. These findings are consistent with other studies that have demonstrated the importance of FCS for both cryopreservation and in vitro culture (Abedelahi et al 2008). This might be attributable to the role of FCS as a survival factor and a promoter of follicular development (Mao et al 2002;Basso et al 2007).…”

Goat ovarian cortex fragments were subjected to slow freezing in the presence of various solutions containing intracellular cryoprotectants, including 1.0 M ethylene glycol (EG), propanediol (PROH), or dimethyl sulfoxide (DMSO), with or without sucrose and/or fetal calf serum (FCS). Histological examination revealed that only the DMSO-containing solutions were able to maintain a follicular ultrastructure similar to the morphology observed in the fresh control. Therefore, fragments previously cryopreserved in DMSO solutions (with and without sucrose and/or FCS) were cultured in vitro for 48 h and then subjected to viability, histological, and ultrastructural analysis. No significant differences were observed among the percentages of morphologically normal follicles in cryopreserved ovarian tissue before in vitro culture (DMSO: 62.5%; DMSO + sucrose: 68.3%; DMSO + FCS: 60.0%; DMSO + sucrose + FCS: 60.0%) and after culture (DMSO: 60.8%; DMSO + sucrose: 64.2%; DMSO + FCS: 70.8%; DMSO + sucrose + FCS: 55.0%). Following in vitro culture, the viability analysis showed that only the freezing solution containing DMSO and FCS (75.6%) maintained a percentage of viable follicles similar to that observed after culture without cryopreservation (89.3%). As determined by ultrastructural analysis, morphologically normal preantral follicles were detected in the fresh control and in fragments cultured before and after cryopreservation with DMSO and FCS. Thus, a freezing solution containing DMSO and FCS, under the experimental conditions tested here, guaranteed the maintenance of viability and follicular ultrastructure after short-term in vitro culture.

“…Similarly, in another in vitro culture study [76] on porcine parthenotes, a higher rate of blastocysts, cell number, and inner cell mass (ICM) rate were observed when Se (25 and 250 ng/mL sodium selenite) was added to the culture media. Se supplementation (10 ng/mL sodium selenite) in culture media was also able to improve the in vitro maturation rate of mouse preantral follicles [85]. Same group also reported an increased in vitro developmental potential of vitrified mouse preantral follicles following Se supplementation in in vitro culture media [86].…”

Dietary Selenium Supplementation Ameliorates Female Reproductive Efficiency in Aging Mice

Female reproductive (ovarian) aging is distinctively characterized by a markedly reduced reproductive function due to a remarkable decline in quality and quantity of follicles and oocytes. Selenium (Se) has been implicated in playing many important biological roles in male fertility and reproduction; however, its potential roles in female reproduction, particularly in aging subjects, remain poorly elucidated. Therefore, in the current study we used a murine model of female reproductive aging and elucidated how different Se-levels might affect the reproductive efficiency in aging females. Our results showed that at the end of an 8-week dietary trial, whole-blood Se concentration and blood total antioxidant capacity (TAOC) were significantly reduced in Se-deficient (0.08 mg Se/kg; Se-D) mice, whereas both of these biomarkers were significantly higher in inorganic (0.33 mg/kg; ISe-S) and organic (0.33 mg/kg; OSe-S) Se-supplemented groups. Similarly, compared to the Se-D group, Se supplementation significantly ameliorated the maintenance of follicles and reduced the rate of apoptosis in ovaries. Meanwhile, the rate of in vitro-produced embryos resulting from germinal vesicle (GV) oocytes was also significantly improved in Se-supplemented (ISe-S and OSe-S) groups compared to the Se-D mice, in which none of the embryos developed to the hatched blastocyst stage. RT-qPCR results revealed that mRNA expression of Gpx1, Gpx3, Gpx4, Selenof, p21, and Bcl-2 genes in ovaries of aging mice was differentially modulated by dietary Se levels. A considerably higher mRNA expression of Gpx1, Gpx3, Gpx4, and Selenof was observed in Se-supplemented groups compared to the Se-D group. Similarly, mRNA expression of Bcl-2 and p21 was significantly lower in Se-supplemented groups. Immunohistochemical assay also revealed a significantly higher expression of GPX4 in Se-supplemented mice. Our results reasonably indicate that Se deficiency (or marginal levels) can negatively impact the fertility and reproduction in females, particularly those of an advancing age, and that the Se supplementation (inorganic and organic) can substantiate ovarian function and overall reproductive efficiency in aging females.

Purpose This study was designed to investigate the effect of alpha-lipoic acid (ALA) on reactive oxygen species (ROS) production, total antioxidant capacity (TAC) and developmental competence of cultured pre-antral follicles derived from mouse ovarian tissue. Methods Pre-antral follicles were isolated from immature mouse ovaries and were cultured in α-minimal essential medium supplemented with different concentrations (0, 50, 100, 250 and 500 uM) of ALA. Follicular growth, oocyte maturation and embryo development were evaluated. Separately, ROS and TAC were measured after 0, 24, 48, 72 and 96 h of culture with spectrofluorometery and ferric reducing/antioxidant power (FRAP) assay, respectively. Results In the presence of 100 uM ALA, developmental rates of follicles, oocytes and embryos were significantly higher than other groups (p<0.05). At 96 h after culture, a decrease in ROS and an increase in TAC were observed in ALA group compared to control group (p<0.05). Conclusion ALA (100 uM) improves the in vitro development of follicles. This effect may be mediated by decreasing ROS concentration and increasing follicular TAC level during the culture period.
