    Análisis de las variables del espermiograma en jóvenes sanos en Arica-Chile
    (Sociedad Medica de Santiago, 2010) Espinoza Navarro, Omar; Cortés Arancibia, Sandra; Monreal, Julio; Ferreccio Readi, Catterina
    Background: Semen analysis is one of the parameters used to predict male fertility. Semen can be altered by environmental pollutants; therefore it could be used as a biological marker of exposure in contaminated areas. Aim: To analyze the spermogram values in a sample of healthy young males, residing in Arica, Chile. Material and methods: One hundred and two healthy university students volunteers aged 18 to 30 years answered a questionnaire about fertility, habits and andrologic diseases and provided a semen sample. Within three hours after ejaculation, semen volume, pH, sperm concentration, motility and morphology were analyzed. Results: Six percent of volunteers had offspring, 1% declared to be infertile, 32% smoked and 78% consumed alcohol. Semen pH was 7.6 +/- 0.5, volume, 2.9 +/- 1.6 ml, sperm concentration, 62.8 +/- 62.3 x 10(6)/ml, normal morphology, 15.0 +/- 7.9%, overall motility, 42.2 +/- 23.2% and grade A motility, 19.2 +/- 18.6%. The percentage of subjects that had normal semen values was 82% for total sperm count, 76% for sperm concentration, 72% for volume, 64% for vitality, 63% for pH, 57% for morphology, 38% for overall motility and 26% for grade A motility. Conclusions: This sample of healthy young males had a normal sperm count in comparison with international reports. However it is necessary to characterize the spermogram in uncontaminated areas of Chile to ensure that our results are within the expected values for the country.

    Profile of morphology teachers in chilean universities
    (2021) Farfán C., Emilio; Cárdenas, Julio; Espinoza Navarro, Omar; Lizana, Pablo A.; Pacheco, Juan; Salinas, Paulo; Riveros, Andrés; Villarroel, Mauricio
    University teaching in Chile has been influenced in recent decades by changes to the education system, which has increased universities and academic offerings and, therefore, the demand for new instructors. Teaching morphological sciences has not been exempt from these changes, with new instructors needed to fill the growing offerings of programs that include anatomy, embryology and histology. The aim was to understand the profile of the academics teaching morphology in Chile in 2020. A voluntary online survey was applied to 213 university morphology teachers, in which information was collected on professional and academic training, geographical distribution, gender, continuing academic education and employment situation. Overall, the results show that 65.9 % of instructors were men and 35.1 % women, and most (34.6 %) had between 5 and 10 years in morphology, and a master's degree was predominant (53.27 %). In the area of anatomy, 46 % of instructors were physiotherapists and 24.6 % dentists, whereas in the areas of histology and embryology, the group was diverse. In terms of employment, 49.06 % stated they worked full time, mainly in teaching .41.31 % of the instructors were concentrated in the Metropolitan Region. There was no association between gender and graduate training, maximum academic degree attained, type of workday or academic profile, but there was one by disciplinary area. The conclusion drawn is that morphology teachers in Chilean universities are part of a wide range of professionals dedicated to different disciplinary areas, with master's degree and/or specialization, located mainly in the Metropolitan Region. This multidisciplinary profile demonstrates the mainstreaming of morphology teaching in Chile.
