Overview of the Sexual Response Cycle

The sexual response cycle is a term referencing the changes that occur within the body as it is becoming aroused (Nevid & Rathus, 2010). This cycle, the sexual response cycle, consists of four phases. Phase one is excitement. Phase two is plateau. Phase three is orgasm. Phase four is resolution. Even though the changes that occur in men’s and women’s bodies differ in each phase, they do have some things in common. So that we may learn and better understand what makes us different and the same, we must first learn the components that make up the sexual response cycle. There are two components and they are vasocongestion and myotonia (Nevid & Rathus,

Focusing on just natural clarifications of human conduct, the Biological Theory trusts that physiological variables tremendously affect sexual conduct. Scholars regularly take a gander at anomalous hormonal and androgenic levels in the body and cerebrum to depict freak sexual practices as in rising hormones are identified with physical changes that advance sexual excitement, climax, discharge, and other sexual movement. "In spite of the fact that a survey of natural studies indicates clashing results about the relationship between

The SRY gene is a very important aspect in determining the sex of an individual. In fact it is the SRY that specifically could be seen as the powerhouse machine in determining the sex of an individual. The SRY gene commonly called the Sex Determining Region of the Y- chromosome can normally cause the testis to develop rather than an ovary when it is presented in the chromosome. The function of the SRY gene is to provide a set of instructions for making the Sex-Determining region of the Y protein, which can also perform as a transcription factor, binding to specific regions of DNA and aid in the control and regulation of particular genes. Changes

However, sometimes the individual or couple may encounter problems in one or several areas of these events. According to Sewell (2005), sexual dysfunctions are characterized as impairment or a disturbance in one or more of the basic stages of the sexual response cycle. The four phases associated that can determine normality or a state of functioning is desire, arousal, orgasm and resolution (Sewell, 2005). When these phases are not interrupted the sexual response cycle varies from person to person and “even from time to time within persons” with no single, normal, or correct sexual response (Sewell, 2005). The first phase of the sexual response cycle, desire encompasses the want or libido to engage in sexual behavior. This phase is followed by arousal which progresses at varied rates between men and women with men progressing quicker than women. Women need foreplay and intimacy to become physically aroused. In this phase, physical signs of this are vaginal lubrication in women and penile erection in men, with accelerated breathing in both. Through physical touch and intercourse, arousal progress toward orgasm. The succession from the last phase of arousal to orgasm varies between men and women, while both experience muscle contractions, men are able to achieve this quicker with

The male and female primates have different reproductive strategies. The female’s approaches are similar in all the species while those of males differ according to the species that they belong (Bercovitch, 1991). Female primates invest in their offspring in terms of time and energy. They provide food for the infant even if it means competing with other females until the infant can look after itself. At this point, the female can focus on getting another offspring. However, the number of offspring that she will get is limited by the gestation and lactating periods (Winkler, 1988). Males do not contribute in the nurturing of the infant but may protect it from predators to some extent. The number of babies they can have is unlimited since they can mate with as many females as they want.

This research is comprised of 32 sexually active females for the experiment on classical conditioning for sexual response. This research is about observing conditioned genital responses in females using diverse conditioning measures and genital vibrostimulation and unconditional stimulus (US). Neutral pictures were used as conditional stimuli (CS) and the genital vibrostimulation as the unconditional stimuli (US). Instruments used included pictures, genital vibrator, and a computer program for time supervision. The CS+ produced more VPA results than the CS-. In addition, the genital and individual sexual responses were successfully modulated by the differential conditioning pattern.

Still working on the similarities and differences between humans and their ancestries, in Sex at Dawn we can find, for example, a very interesting discussion about human female orgasm, in where the authors of the book point out that female orgasmic behavior has been observed in some primate species with multimale- multifemale mating systems, whereas the monogamous gibbon female does not exhibit such behavior. Following this, Symons’ (1979) by-product argument is summarized, and a few pages later, changes in vaginal

“These data are interesting because they suggest that orgasm is not necessarily a sexual event, and they may also teach us more about the bodily processes underlying women’s experiences of orgasm.”

Doctors prescribe hormone therapy for females who have had their ovaries removed, stopped having periods at a young age, or are currently menopausal. Women who are menopausal typically experience hot flashes, irritability, vaginal dryness, or other symptoms of menopause. Males typically receive hormone therapy to treat low testosterone levels; however, recent research has led to hormone therapy being used to treat men with prostate cancer. This entry will explain the psychological implications of hormone therapy for men and women by comparing the biochemical effects

1.The Masters and Johnson model of sexual response has four different phases: excitement, plateau, orgasm, and resolution

This item, Comparing Asexual and Sexual Reproduction, allows students to evaluate and communicate information about the basic similarities and differences between the two types of reproduction. Extend this item by having students create a two-column chart with headers “Asexual Reproduction” and “Sexual Reproduction” into which they add descriptions of organisms according to their mode of reproduction. This can be an ongoing project throughout the remainder of the lesson, giving students the opportunity to research and obtain information about different types of organisms and communicate this information via their

The changes and responses that occur in the body of both men and women when sexually aroused are referred to as the sexual response cycle. The sexual response cycle is divided into four separate phases which include excitement, plateau, orgasm, and resolution. These changes are similar for both men and women. According to Nevid and Rathus (2005), each phase is characterized by vasocongestion and myotonia. Vasocongestion is the swelling of the genital tissues with blood, and myotonia is the muscle tension associated with sexual arousal. Although the changes are similar, there are some differences in the way these changes affect men and women.

During 2015, the reproductive cycles of two female, captive, Southern White Rhinoceroses (Ceratotherium simum simum), Moesha (#1357) and Kito (#1353) at Hamilton Zoo were investigated and analysed by non-invasive faecal progesterone concentrations. These two females have had limited reproductive success with one in a long period of acyclicity and the other with normal cycles. Monitoring progesterone levels allows the zoo keepers at Hamilton Zoo to be able to introduce the male Kruger (#1273) when the females are in oestrous (especially if no reproductive behaviour has been observed, to predict pregnancies and to document reproductive health.

Throughout history it is evident that human sexuality changes do to religious, governmental and societal influences. The perception of human sexuality has gone through many changes such as being very open and unlabeled activity; to being very “conservative” and a topic that shouldn’t be talked about in public or at all. In any case, human sexuality has always been a topic of interest because humans are sexual beings who want to understand the consciousness of themselves as male or female and see their personal response when encountered in erotic experiences with other individuals. Unlike many other species whose sexual force is strictly for reproduction, human’s sexual drive seems to be driven by many factors that intertwine with each other which leads to very different outcomes. Do to these obscure human emotions and personal gratification, sex is always shown every culture’s art, literature, social norms, and laws.
