Ejaculation dysfunction

Francesco Lotti, Mario Maggi
Infertility affects up to 12% of all men, and sexual dysfunction occurs frequently in men of reproductive age, causing infertility in some instances. In infertile men, hypoactive sexual desire and lack of sexual satisfaction are the most prevalent types of sexual dysfunction, ranging from 8.9% to 68.7%. Erectile dysfunction and/or premature ejaculation, evaluated with validated tools, have a prevalence of one in six infertile men, and orgasmic dysfunction has a prevalence of one in ten infertile men. In addition, infertile men can experience a heavy psychological burden...

Diabetes mellitus is associated with the impairment of sexual function including desire and orgasmic dysfunction. Sexual dysfunction in the diabetes mellitus is due to a selective defect of the nitric oxide synthase (NOS) within paraventricular nucleus (PVN). c-Fos is an immediate early gene and c-Fos expression represents neuronal activity in response to various stimuli. In the present study, we investigated the effects of treadmill exercise on sexual behaviors and the expressions of NOS and c-Fos in the PVN were evaluated using streptozotocin (STZ)-induced diabetic rats...

The effects of aqueous extract of Brysocarpus coccineus roots (AEBCR) were studied on sexual behaviour and testicular function of paroxetine-induced sexual dysfunction (SD) in male rats. Ninety, sexually matured male rats (150.88 ± 5.53 g) were assigned into two groups: A and B. Fifteen SD animals from group B were each allotted to B1, B2, B3, B4 and B5 and received distilled water (DW), Powmax M (7.14 mg/kg body weight, b.w.) 50, 100 and 150 mg/kg b.w of AEBCR, respectively, for 7 days while the non-SD animals (group A) received DW...

BACKGROUND: Ejaculation consists of the emission of semen from seminal vesicles and prostate, followed by expulsion. Ejaculatory dysfunction may take several forms including premature ejaculation, delayed or anejaculation, retrograde ejaculation, and painful ejaculation. Ejaculation is what we can see whereas orgasm is what we feel. The presence of ejaculate does not indicate the ability to experience orgasm. Hence, for the purpose of this work we consider orgasm and ejaculation as 2 separate neurobiological phenomena...

Klinefelter syndrome is a frequent cause of hypogonadism, but despite hundreds of publications on different aspects of Klinefelter syndrome, only a few studies dealt with sexual dysfunction. In particular, testosterone is critical for various aspects of sexual response, but its role on sexuality in Klinefelter syndrome patients is debatable and no studies have evaluated the efficacy of testosterone treatment on sexual dysfunction in these subjects. Furthermore, the impact of psychological and relational aspects on sexual function of Klinefelter syndrome subjects is poorly defined...

The 5-α-reductase inhibitors finasteride and dutasteride are frequently used in the treatment of androgenetic alopecia and benign prostatichyperplasia. These drugs are effective at reducing levels of dihydrotestosterone, the primary androgen responsible for the pathogenesis of both these conditions. However, finasteride and dutasteride have also been shown to produce an increase in the incidence of sexual dysfunction, namely, impotence, decreased libido, and ejaculation disorder. The purpose of this study is to review the existing medical literature with regard to the sexual side effects of 5-α-reductase inhibitor therapy...

Unconsummated marriage are mainly due to vaginismus or erectile dysfunction. They contribute to about 5% of couples in an infertility clinic. Their incidence is increasing in the metropolitan cities because of stressful lifestyles. Many of couples are advised intrauterine insemination as fertility treatment. However, home insemination is a simple, inexpensive and effective way of achieving pregnancy in such couples. We present the first study to document pregnancy rates of artificial home intravaginal insemination in couples with unconsummated marriage...

The BCR consists of the contraction of the bulbocavernosus muscle in response to squeezing the glans penis or clitoris, and is mediated through the pudendal nerve. In case of a complete lesion, the presence of BCR is indicative of intact S2-S4 spinal reflex arcs and loss of supraspinal inhibition, determining an upper motor neuron (UMN) lesion, its absence a lower motor neuron (LMN) lesion. The BCR further helps distinguish conus medullaris from cauda equina syndromes. Sensory or motor function in the most caudal sacral segments, not BCR, defines the sacral sparing as part of the International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI)...

Penile hypersensitivity plays an important role in premature ejaculation (PE), but differences in penile sensitivity among subtypes of PE are unknown. Therefore, we compared penile sensory thresholds in PE subtypes of lifelong and acquired PE, PE with and without erectile dysfunction (ED), PE with an intravaginal ejaculation latency time ≤1 min and >1 min, and PE with and without orgasmic pleasure perceptual dysfunction. During August 2014 to January 2016, 136 patients with PE were included. Penile warm, cold, and vibratory thresholds were measured...

Androgenetic alopecia, generally recognized as male pattern baldness, is a gradually developing medical and physiological change, which is manifested by continuous hair-loss from scalp. Finasteride (4-aza-3-oxosteroid) is a potent anti-baldness compound that selectively and competitively inhibits the 5α-reductase isoenzymes. Prolonged oral use of finasteride leads to the emergence of sexual disorders including decrease in libido, gynecomastia, erectile dysfunction, ejaculation disorder, orgasm disorders and mood disturbances...

Delayed ejaculation (DE) is a poorly defined and uncommon form of male sexual dysfunction, characterized by a marked delay in ejaculation or an inability to achieve ejaculation. It is often quite concerning to patients and their partners, and sometimes frustrates couples' attempts to conceive. This article aims to review the pathophysiology of DE and anejaculation (AE), to explore our current understanding of the diagnosis, and to present the treatment options for this condition. Electronic databases were searched from 1966 to October 2017, including PubMed (MEDLINE) and Embase...
