Men's sexual response to female partner's intranasal oxytocin administration for hypoactive sexual desire disorder: an open prospective cohort study

Evaluation of male sexual parameters in infertile couples with a history of abortion

INTRODUCTION

It is thought that both individuals are affected psychologically and sexually in couples experiencing abortion. In addition to the stress caused by infertility, sexual life may also be negatively affected in couples who experience psychogenic wear, such as abortion and curettage. The aim of this study is to evaluate male sexual functions in infertile couples with a history of abortion and male infertility component.

METHODS

Five hundred forty-seven male patients' data were evaluated retrospectively. Group 1 was the included the males of the couples without abortion history and the rest with abortion history was group 2. In addition to demographic data, abortion history, libido level, presence of morning erection and intercourse frequency were evaluated. Hormone levels of all patients were evaluated. After that we created sub-group 1 and sub-group 2 from these groups, respectively, due to whether the patients fulfilled the international index of erectile function (IIEF), Beck anxiety inventory (BAI) and Beck depression inventory (BDI).

RESULTS

There were not any significant differences between the groups regarding psychiatric scale scores, hormone levels, libido, intercourse frequency and IIEF scores. Only orgasmic dysfunction was significant in the males of the couples with abortion history.

CONCLUSION

Man is not affected from abortion process in which woman get involved. Men only have orgasmic dysfunction when there is one or more abortion history in couples.

Oxytocin, Erectile Function and Sexual Behavior: Last Discoveries and Possible Advances

A continuously increasing amount of research shows that oxytocin is involved in numerous central functions. Among the functions in which oxytocin is thought to be involved are those that play a role in social and sexual behaviors, and the involvement of central oxytocin in erectile function and sexual behavior was indeed one of the first to be discovered in laboratory animals in the 1980s. The first part of this review summarizes the results of studies done in laboratory animals that support a facilitatory role of oxytocin in male and female sexual behavior and reveal mechanisms through which this ancient neuropeptide participates in concert with other neurotransmitters and neuropeptides in this complex function, which is fundamental for the species reproduction. The second part summarizes the results of studies done mainly with intranasal oxytocin in men and women with the aim to translate the results found in laboratory animals to humans. Unexpectedly, the results of these studies do not appear to confirm the facilitatory role of oxytocin found in male and female sexual behavior in animals, both in men and women. Possible explanations for the failure of oxytocin to improve sexual behavior in men and women and strategies to attempt to overcome this impasse are considered.

I Want You to Want Me: A Qualitative Analysis of Heterosexual Men's Desire to Feel Desired in Intimate Relationships

Current sexual scripts for heterosexual relationships in the Western world stipulate that men should be the ones to initiate sexual activity, push to the next level of physical intimacy, and to desire women (and not be desirable themselves). However, there is building evidence that sexual scripts and gender roles are not only limited, they may be evolving and shifting over time. The purpose of the current study was to explore the degree to which feeling desired is considered important to heterosexual men in intimate relationships as well as how heterosexual men feel desired by their partners. Three hundred men between the ages of 18 and 65 were recruited from the online platform Reddit. Using Thematic Analysis, we determined that the vast majority of men in this study felt that feeling desired was very important to their sexual experiences. Men in this study listed several ways they felt desired, many that fell outside of traditional gender roles such as romantic, non-sexual touch and having women initiate sexual activity. The findings add to a growing body of literature which suggests traditional sexual scripts for heterosexual men may be limiting and not accurate for all men's sexual experiences.

Influence of Genotype and Hyperandrogenism on Sexual Function in Women With Congenital Adrenal Hyperplasia

BACKGROUND

Depending on CYP21A2 genotype, congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency leads to biochemical alterations (including hyperandrogenism, hypocortisolism, and hypoaldosteronism) and a wide spectrum of phenotypic disease manifestation. The latter include life-threatening salt-wasting crises, prenatal virilization of genitalia in women (classic CAH [C-CAH]) as well as milder forms of the disease exclusively presenting with hirsutism, acne or reduced fertility (nonclassic CAH [NC-CAH]), and could influence sexual function and identity.

AIM

The present study evaluated sexual function, gender identification, and partner preference in women with C-CAH and NC-CAH.

METHODS

In a cross-sectional cohort analysis, 35 female patients with CAH were divided into 2 groups: C-CAH (salt-wasting/simple virilizing; n = 17) and NC-CAH (n = 18) according to genotype and phenotype. Sexual function and sexual distress were assessed using established questionnaires, including the Female Sexual Function Index. Phenotype (defined by signs of hyperandrogenism) was assessed clinically (Ferriman-Gallwey score) and with the ovulatory function index. CYP21A2 genotype was determined by Sanger sequencing and multiplex ligation-dependent probe amplification. Sexual function was also separately analyzed in the context of clinical signs of androgenization in women with (n = 13) and without acne (n = 22).

OUTCOMES

The study outcomes were sexual function and sexual distress in relation to genotype, clinical signs of androgenization, and biochemical parameters.

RESULTS

Women with NC-CAH had significantly lower orgasm scores, a trend toward lower sexual function with higher sexual distress, as well as biochemical evidence of hyperandrogenism (higher dehydroepiandrosterone sulfate and lower SHBG) and a trend toward more clinical signs of hyperandrogenism (hirsutism). Indicators of in utero and childhood androgen excess as well as the presence of acne in all patients were related to lower sexual function and higher sexual distress. Clinical signs of hyperandrogenism correlated well with cardiovascular and metabolic risk factors.

CLINICAL TRANSLATION

Women with NC-CAH and women with clinical signs of hyperandrogenism demonstrated higher distress compared to women with C-CAH and women without clinical signs of hyperandrogenism, respectively, regarding different aspects of sexual function.

CONCLUSIONS

These data underline the importance of early diagnosis and therapy initiation, especially in patients with NC-CAH. Schernthaner-Reiter MH, Baumgartner-Parzer S, Egarter HC, et al.

Nose-to-brain peptide delivery - The potential of nanotechnology

Nose-to-brain (N-to-B) delivery offers to protein and peptide drugs the possibility to reach the brain in a non-invasive way. This article is a comprehensive review of the state-of-the-art of this emerging peptide delivery route, as well as of the challenges associated to it. Emphasis is given on the potential of nanosized drug delivery carriers to enhance the direct N-to-B transport of protein or peptide drugs. In particular, polymer- and lipid- based nanocarriers are comparatively analyzed in terms of the influence of their physicochemical characteristics and composition on their in vivo fate and efficacy. The use of biorecognitive ligands and permeation enhancers in order to enhance their brain targeting efficiency is also discussed. The article concludes highlighting the early stage of this research field and its still unveiled potential. The final message is that more explicatory PK/PD studies are required in order to achieve the translation from preclinical to the clinical development phase.
