Title: The Human Embryo in the Perspective of Reproductive Medicine. Since when one begins to be a human person? In this work, we take into account the issues, which in most cases lead many people to resort to the reproductive medicine, which generally is referred to as the infertility problems. But in some techniques, the reproductive medicine loses up to 80% of human embryos. In the minds of many people, the human embryo is seen only as a cluster of cells. However, is it really just a cluster of cells, or is it already a person at an early stage of development? As far as one is already man, is he now also the human being, of whom are in our Western culture related rights, especially the right to life? Could we then say with a clear conscience that with these techniques we are acting ethically? We dividend our work into six chapters. In the first and second chapter, we will be briefly acquainted with the issues of infertility, of the reproductive medicine techniques, with the development of the human embryo and with handling of the embryos in the course of these techniques. In the third charter, we will present the two major ethical models in our cultural area that have a different point of view on the status of the human embryo. In the fourth chapter, we will look at how to the question of the...

Preferences for sexual arousal by overstated dominance and submission in sex is categorized as F65.5, sadomasochism, according to ICD, but this behaviour is called BDSM among the general public. The ground of these preferences could be ultimately biological. These preferences reflect behavioural strategy which enables to gain higher reproductive success. Men and women who were sexually aroused by a submissive partner had more male relatives than men and women with other preferences. Contrary to the women, the dominant men reported themselves as more attractive. Women who were aroused by a higher-ranking partner considered themselves more attractive. Sons of couples in which was hierarchical disparity had more siblings than sons of "equal" couples or couples with no hierarchical disparity. Daughters of hierarchically disparate couples had more brothers than daughters of "both dominant" partners. Concurrently, number and gender of offspring as well as self- reported attractiveness are likely to be criteria of the reproductive success in humans. It is also interesting that hierarchically disparate couples, without regard to gender of higher-ranking partner, reached higher reproductive success than "equal" couples. Individuals who preferred higher- or lower-ranking partner were also aroused by...
