The Reproductive System and Its Disorders

Externally, the penis consists of the body or shaft, which terminates in the glans penis, a cap-like extension of the corpus spongiosum. The word glans is from the Latin for "acorn," so the term is often used for any rounded mass or gland-like structure (for example, glans clitoridis is the erectile tissue at the end of the clitoris). The glans penis is molded into an expanded rim called the corona (from the Greek for "crown," as in coronary). The prepuce or foreskin, a fold of skin between the corona and shaft of the penis, folds forward over the glans unless removed by the surgical procedure known as circumcision.

Mechanical friction and pressure are stimuli which play a dominant role in the triggering of ejaculation during intercourse and masturbation. There are receptors to mechanical stimuli particularly in the glans penis and also in other regions of the penis. Signals from the activated receptors travel to nerve centers responsible for ejaculation. Electroejaculation, which was discussed earlier, is essentially a means of exciting these same centers directly, bypassing the mechanical sensory receptors and some of the neural pathways from the receptors to the ejaculation center. Some subjects have the receptors and neural pathways intact but still do not achieve an ejaculation by intercourse or by masturbation. This state may be a sequel to a number of conditions such as spinal cord injury, alcoholism, and psychogenic aberrations. Possibly there may not be any morphological deficiencies per se and it may only be that the threshold of activation has increased. Giving stimuli at higher intensity than possible in the normal sexual act may help cross the threshold and trigger ejaculation. An alternative form of stimulus, for example a vibration, may also have the same effect at a lower and better tolerated stimulus intensity. Vibratory ejaculation is based on this concept.
ENTRIES A–Z

Orgasms are typically generated by somatosensory stimulation of the genitals during masturbation or sexual intercourse, and the pattern of preferred stimulation differs for different individuals. Some women prefer gentle and indirect massaging of the CLITORIS, whereas others prefer quick and direct clitoral contact. Still other women may prefer vaginal stimulation to achieve orgasm. Some women prefer a single, intense orgasm whereas others prefer many quick orgasms of small intensity. Likewise, in some men, repeated stimulation of the glans penis may lead to orgasm, whereas for others the entire penile shaft must be stimulated. Some men prefer quick and intense genital stimulation, whereas others prefer less intense genital stimulation and more whole-body touching. Delayed or inhibited orgasm can occur in both men and women following use of any DRUG that inhibits SYMPATHETIC AROUSAL, or if STRESS or control issues pervade the relationship or the sexual act.

Fixed drug eruptions (FDE) are usually characterized with solitary erythematous or dark red macular, plaque or bullous lesions. These lesions may be solitary or in multiple numbers. Most importantly, lesions develop in the same region with repetitive exposures of triggering agents. The development of these lesions can take several hours, days, or even years at the first episode [2,3]. Among the frequently accused drugs are various antibiotics, non-steroidal anti-inflammatory drugs, barbiturates, allopurinol, metronidazole, pirantel pamoad, albendazole, sulfonamides, tetracycline, carbamazepine phenolphthalein, and griseofulvin [4]. Lesions mostly prefer intertriginous areas and genital area. In male patients, glans penis involvement is typical. Lesions regress after leaving post-inflammatory pigmentation. This pigmentation increases with each repeated attack [3,4]. In our case, the lesions started in genital area on the second day of treatment and oral mucosa lesions appeared on the fourth day of treatment. The presence of lesion in genital areas helped us for differential diagnosis. Furthermore, another method helping diagnosis was the patch test. The tests prepared with trigger agents are administered on the lesion areas (in varying concentration with saline or petrolatum). In our case, we could not perform a test because the lesions were on unappropiate areas for test [6,7].
In Pursuit of Pleasure: A Biopsychosocial Perspective on Sexual Pleasure and Gender

In a similar vein, conflating sexuality with reproduction seems to have led to the widely held belief that the sexual act that helps humans reproduce (penile-vaginal intercourse), should also be the most sexually pleasurable. When considering the overwhelming evidence that penile-vaginal intercourse advances heterosexual men’s orgasms, as discussed earlier, this seems like a reasonable thought, at least from a male perspective. This line of thought has inspired researchers to hunt for sexually sensitive locations within the vaginal wall (e.g., Alzate, 1985; Semmens & Semmens, 1978). And even though the anterior vaginal wall has consistently been found to be the spot that is most sensitive to electric stimulation, the vaginal wall is in fact rather insensitive, especially when compared to the sensitivity of the (glans) clitoris (Weijmar Schultz et al., 1989). Having a relatively insensitive vaginal wall may make perfect sense when it comes to reproduction, with women’s vagina’s having to accommodate a baby’s head of approximately 10 cm in diameter during delivery. Labeling the vagina a reproductive rather than a sexual organ would help women to no longer feel sexually dysfunctional when they have difficulty becoming sexually aroused, let alone experience orgasm, from penile-vaginal intercourse without direct or indirect stimulation of their pleasure organ, the clitoris. After all, who would expect men to reach orgasm without stimulation of the (glans) penis?
Outcome of hyaluronic acid gel injection in glans penis for treatment of lifelong premature ejaculation: A pilot study

This result can be attributed to a lowered glans penis sensory threshold [16]. The delayed digestion of this gel demonstrates that cross-linkage stabilization of the material can enhance the lifespan of the natural polymer by several hundred times without biocompatibility reduction. There is deterioration of the implant, but it exhibits an isovolemic degradation feature. As a result of the isovolemic degradation, a less concentrated hyaluronan network has a greater capacity to bind water, which permits the correction to be maintained even at low concentrations of the materials [17].
