Delayed ejaculation (DE) is a sexual health condition in which a man takes a long time to ejaculate or is unable to ejaculate, particularly during partnered sex. It can also refer to a significant increase in the time it takes a man to ejaculate during sex compared to his previous “normal.” Often, ejaculation latency time is discussed with regard to DE, which is the time it takes a person to ejaculate during penetrative sex.

The clitoris is an organ that is central to female sexual pleasure, yet very little was known about it until recently. Unlike its anatomical counterpart, the penis, which was accurately described as early as 35 BCE by Hippocrates, the clitoris was not fully anatomically described until the year 2005. This historical neglect of the clitoris has led to some major consequences for patients, health care professionals, and society as a whole.

Historically, there has been a considerable lack of research on care for transgender individuals. Expanding on this data could go a long way toward addressing the health inequities that disproportionately affect this group as well as toward understanding and meeting their unique health care needs.

Priapism is a long-lasting, unwanted, and often painful erection. Individuals who have an erection for more than four hours should seek emergency medical care to mitigate any potential damage to the penis. Even when priapism is addressed quickly and properly, it can lead to sexual dysfunction such as erectile dysfunction (ED), Peyronie’s disease (PD), or recurrent priapism.

Many studies have shown there is a strong association between relationship satisfaction and sexual satisfaction. Couples who communicate well and maintain a close connection with one another also tend to be more satisfied with their sex life, whereas couples who experience discord in their relationship may feel less satisfied with their sex life.

Prostate cancer treatments often have a negative impact on a man’s sexual function. However, to date, most of the research on prostate cancer and sexual dysfunction centers on erectile dysfunction, even though this cancer and its treatments may cause other sexual difficulties.

Pregnancy causes several physical and hormonal changes in a woman’s body. These changes can have an impact on the expectant mother’s sexuality and sexual function.

Menopause is a transition that occurs for women in mid-life when their monthly menstruation cycle stops. When this happens, the body’s estrogen levels drop, which can cause hot flashes and night sweats (vasomotor symptoms), vaginal dryness, pain with intercourse, and changes in mood.

Sexual dysfunction, mental health issues, and relationship dissatisfaction are often interrelated issues. Past studies have shown a relationship between relationship quality and sexual satisfaction that is bidirectional, meaning that it occurs in both directions. If a person is satisfied in their relationship, they are more likely to be satisfied with their sex life and vice versa. On the other hand, if a person is dissatisfied in their relationship, they are more likely to experience sexual dissatisfaction.

The clitoris is a historically understudied part of human anatomy. Despite its significant role in sexual pleasure and functioning in women, accurate descriptions of this organ are difficult to find. In fact, the lack of scientific information on the clitoris may be due in part to the persisting taboo around female sexuality and pleasure.

A person’s gender identity refers to their deeply held sense of self with regard to their gender. This gender identity can match the sex a person is assigned at birth (i.e., cisgender individuals) or it may be the “opposite” of the sex a person is assigned at birth (i.e., transgender individuals). Furthermore, some individuals have a gender identity that lies between or beyond the binary view of gender and may identify as nonbinary, genderqueer, gender fluid, gender expansive, or another identity.

Peyronie’s disease (PD) is a sexual health condition that affects up to 13% of the adult men in the United States. In men with PD, plaques of scar tissue form under the skin of the penis, causing it to curve or take on a deformity when it is erect. This can lead to painful erections, erectile dysfunction (ED), low self-esteem, mental health issues, and relationship difficulties.
