Females are the larger sex in a majority of animals.[81] For instance, female southern read more black widow spiders are typically twice bey long birli the males.[84] This size disparity may be associated with the cost of producing egg cells, which requires more nutrition than producing sperm: larger females are able to produce more eggs.

The brain is its own pleasure center during sex. Just being physically close with another human being is known to increase levels of oxytocin — the “cuddle hormone” — in the brain, making you feel happy and safe.
At the microscopic level, single-celled organisms reproduce continually by growing and dividing successively to give rise to enormous populations of mostly identical descendants. All such reproduction depends on the capacity of cells to grow and divide, which is a basic property of life. In the case of most animals, however, particularly the higher forms, reproduction by nonsexual means is apparently incompatible with the structural complexity and activity of the individual.
Because the life span of all individual forms of life, from microbes to man, is limited, the first concern of any particular population is to produce successors. This is reproduction, pure and simple. Among lower animals and plants it may be accomplished without involving eggs and sperm. Ferns, for example, shed millions of microscopic, nonsexual spores, which are capable of growing into new plants if they settle in a suitable environment. Many higher plants also reproduce by nonsexual means. Bulbs bud off new bulbs from the side. Certain jellyfish, sea anemones, marine worms, and other lowly creatures bud off parts of the body during one season or another, each thereby giving rise to populations of new, though identical, individuals.

There is a growing consensus that sexual health cannot be achieved and maintained without respect for, and protection of, certain human rights. The working definition of sexual rights given below is a contribution to the continuing dialogue on human rights related to sexual health.
Sex helps the spread of advantageous traits through recombination. The diagrams compare the evolution of allele frequency in a sexual population (tamamen) and an asexual population (bottom). The vertical axis shows frequency and the horizontal axis shows time. The alleles a/A and b/B occur at random. The advantageous alleles A and B, arising independently, sevimli be rapidly combined by sexual reproduction into the most advantageous combination AB. Asexual reproduction takes longer to achieve this combination because it can only produce AB if A arises in an individual which already has B or vice versa. The biological cause of an organism developing into one sex or the other is called sex determination.
Encyclopaedia Britannica's editors oversee subject areas in which they have extensive knowledge, whether from years of experience gained by working on that content or via study for an advanced degree. They write new content and verify and edit content received from contributors.
Although some churches are discreet on the subject, other evangelical churches in United States and Switzerland speak of a satisfying sexuality birli a gift from God and a component of a harmonious Christian marriage, in messages during worship services or conferences.[186][187] Many evangelical books and websites are specialized on the subject.[188]
