Empirical studies regarding embryo donation in developed countries show that the most probable action would be to discard surplus embryos and, if they would donate them, the preferred option would be for research, and eventually to other couples. There are not enough studies in Hispanic America about the opinions of those who have participated in assisted reproductive technologies (ART) regarding embryo disposition of surplus embryos. Moreover, there are scarce specific laws regulating ART in order to contrast people’s opinion. Works performed in Ecuador, Chile and Peru are also preceding works and basis to design a Latin American Study on embryo donation. It is necessary to perform a descriptive study on Latin American couples opinions regarding embryo donation, which would benefit several areas (clinical practice, research, bioethics, biolaw, etc.).

Objective: To explore patients undergoing complex assisted reproductive technologies’ (ART) opinions on both gamete and embryo donation, as well as the reasons to do it or not. Design: Cross-sectional study of descriptive bioethics, with ethnographic qualitative methodology using a semi-structured interview, applying speech analysis to the resulting written transcript. Setting: Private medical institution, in Lima, Peru. Participants: Twenty women and 12 men who had had at least one complex ART. Interventions: Semi-structured interview, applying speech analysis to the resulting written transcript. Main outcome measures: Opinion on both gamete and embryo donation. Results: Regarding embryo donation, 11 men would donate their embryos for infertility treatment, 6 for research purposes, and only one rejected both possibilities. On the other hand, all 20 women would donate embryos for infer...

We do an updated revision in regards to the current concepts of biology-based early development (combining knowledge of cell biology and molecular genetics), in an accessible way and considering implications of basic science on clinical practice. Didactically we divide the mechanism of human fertilization in several phases: sperm activation, incorporation of the sperm the ovum cytoplasm, metabolic activation of the ovum. pronuclei formation, pronuclei migration, and initiation on of the first cellular division and initial development. Some special considerations are also done regarding the mechanisms al epigenetic regulation in early development, and some implications on biological development in scientific names identifying these stages.
