“…Alterations in the microenvironment of oocytes in the FF have been suggested to influence oocyte quality from maturation to fertilization, early embryo development, and subsequent pregnancy course [13]. Experimental and clinical studies indicate that growth and fertility are strongly affected by trace element (TE) supply, and deficiencies are known to impair both male and female gametogenesis as well as embryonic development [14][15][16][17][18]. In particular, the trace elements copper (Cu), selenium (Se), and zinc (Zn) have emerged as the most essential micronutrients for both female and male fertility [19][20][21][22][23].…”

Female subfertility is a growing concern, especially in view of an increasing prevalence of polycystic ovary syndrome (PCOS). Assisted reproductive technologies (ART) offer a perspective for pregnancy, but the outcome rate is still suboptimal. The trace elements (TE), copper (Cu), selenium (Se), and zinc (Zn) are essential for fertility and development. We hypothesized that TE concentrations are related to oocyte quality and growth and affect pregnancy outcomes in women undergoing ART. Concentrations of TE were measured by total reflection X-ray fluorescence. Extracellular glutathione peroxidase 3 (GPX3) and selenoprotein P (SELENOP) were determined as additional Se biomarkers. Corresponding serum and follicular fluid (FF) samples were available from women with (n = 20) and without (n = 20) PCOS diagnosis undergoing hormone treatment within the ART procedure, respectively, and FF samples were classified into five groups based on morphological assessment. Serum showed higher TE concentrations than FF, and TE levels correlated positively between both matrices. Individual FF from the same women showed surprisingly high variability in TE concentration, and follicles without oocytes displayed the lowest TE concentrations. Both Se biomarkers GPX3 and SELENOP were present in FF and correlated positively to Se concentrations. Some notable relationships were observed between morphokinetic parameters, TE concentrations, and GPX3 activity. A slightly depressed serum Zn concentration was observed in PCOS. Our results indicate a direct relationship between TE in serum and FF, positive correlations between the three Se biomarkers in FF, and high variability between the FF from the same woman with the lowest TE concentrations in the follicles with the poorest quality. The differences observed in relation to PCOS diagnoses appear relatively minor. Collectively, the data support the notion that TE assessment of follicles may contribute to optimal oocyte selection and subsequently influence ART success.

La endometritis se define como la inflamación del endometrio, y es considerada una de las principales causas de sub e infertilidad en la yegua, que generan pérdidas económicas significativas, con una incidencia del 10 al 15 %. Existen diferentes etiologías, destacándose la mala conformación del perineo, útero abdominal, pérdida de la actividad miometrial, número de montas, factores moleculares y genéticos, y la presencia de bacterias y hongos. El presente artículo expone el caso de una yegua criolla colombiana de 15 años con historial de abortos y nula obtención de embriones, donde fueron realizados como métodos diagnósticos la evaluación del sistema genital externo e interno, ultrasonografía, citología, cultivo y biopsia endometrial; la cual reportó endometritis crónica de clasificación II B, asociada edema tipo 4, y estableciendo un pronóstico reservado para la reproducción, después de comprobarse la endometritis fúngica. El tratamiento consistió en la utilización de complejos vitamínicos, medicina biorreguladora, terapia antimicótica y antibiótica, nutraceúticos, minerales, y lavados intrauterinos. Posterior a la medicación y tres intervalos ovulatorios consecutivos, fueron recuperados y transferidos exitosamente cuatro embriones, de los cuales tres llegaron a término, demostrando así la recuperación de la función endometrial, gracias a la identificación de los microorganismos involucrados y el establecimiento de una terapia adecuada y complementada.
