The traditional definition indicates that fertilization is a process of union of the male and female pronuclei for the formation of a new being. It is not just the penetration of a small cell (sperm) in a large (oocyte). It is an intercellular interaction, highly specialized, in which an active gamete other.

Objective: To study the diminishing frequency of exclusive breast feeding and the effect of precocious breast feeding (PBF) and skin- skin contact (SSC) in exclusive breast feeding (EBF). Procedures: Study group (n=30): Skin to skin contact and breast feeding in the first half hour of the child birth and EBF control within 5-15 days. Control group (n=30): The same procedure but without SSC and PBE Prospective longitudinal study. Results: In the study group EBF was present in 93,33% in the first 5 days and in 73,3% in the first 15 days; in the control group EBF was present in 76,67% and 30% (p<0,05), respectively. Risk groups in which EBF decreases: Less than 21 years old, high school urban-marginal procedence and primigravid. Conclusion: The PBF and SSC is determinant to guarantee EBF in a short period.

Responsible Fatherhood (PR) is a constant reality of today and its importance is such that our constitution mentions. Globally, the UN and the Catholic church have addressed the issue by having been dedicated in 1994 to the family.

To determine the seroprevalence of cytomegalovirus in women of childbearing age who work in kindergartens of Lima, identify those capable of acquiring a primary infection (HIV-negative) and factors associated with seroprevalence of cytomegalovirus in this risk group. DESIGN: A total of nine kindergartens who met the eligibility criteria, with a total of 79 women of childbearing age were included. The information was gathered from questionnaires. All women underwent including the AxSYM CMV 1gG to detect antibodies against cytomegalovirus 1gG. The information collected was processed using frequency analysis and to determine the association contingency coefficient (C) and chi-square test for significance was calculated. RESULTS: The seroprevalence (serology) was found 72.1%, what determines a percentage susceptibility of 27.8% (22 subjects). The associated seropsitividad moderate and statis...
