Fulltext Serotonin reuptake inhibitor citalopram inhibits GnRH synthesis and spermatogenesis in the male zebrafish

Prasad P, Ogawa S, Parhar IS

Selective serotonin reuptake inhibitors (SSRIs) are widely used antidepressants for the treatment of depression. However, SSRIs cause sexual side effects such as anorgasmia, erectile dysfunction, and diminished libido that are thought to be mediated through the serotonin (5-hydroxytryptamine, 5-HT) system. In vertebrates, gonadotropin-releasing hormone (GnRH) neurons play an important role in the control of reproduction. To elucidate the neuroendocrine mechanisms of SSRI-induced reproductive failure, we examined the neuronal association between 5-HT and GnRH (GnRH2 and GnRH3) systems in the male zebrafish. Double-label immunofluorescence and confocal laser microscopy followed by three-dimensional construction analysis showed close associations between 5-HT fibers with GnRH3 fibers and preoptic-GnRH3 cell bodies, but there was no association with GnRH2 cell bodies and fibers. Quantitative real-time PCR showed that short-term treatment (2 wk) with low to medium doses (4 and 40 μg/L, respectively) of citalopram significantly decreased mRNA levels of gnrh3, gonadotropins (lhb and fshb) and 5-HT-related genes (tph2 and sert) in the male zebrafish. In addition, short-term citalopram treatment significantly decreased the fluorescence density of 5-HT and GnRH3 fibers compared with controls. Short-term treatment with low, medium, and high (100 μg/L) citalopram doses had no effects on the profiles of different stages of spermatogenesis, while long-term (1 mo) citalopram treatment with medium and high doses significantly inhibited the different stages of spermatogenesis. These results show morphological and functional associations between the 5-HT and the hypophysiotropic GnHR3 system, which involve SSRI-induced reproductive failures.

Fulltext Libido, sexuality and the levonorgestrel IUS in Malaysia

Wong CY

J Fam Plann Reprod Health Care, 2001 Jan;27(1):56.

Hysterectomy and tubal sterilisation are two commonly performed gynaecological procedures in Malaysia. Little has been published about the psychological impact on sexuality of such operations in the Far East. Many Malaysian patients believe that surgery to the pelvic organs may be detrimental to the sexual health and needs of women. There is a widespread belief that the uterus is essential for the libido and sexual wellbeing of women. It is also believed that tubal sterilisation may result in the loss of libido and thus of sexual desire for her husband. Despite counselling to dispel these misconceptions, patients frequently refuse surgical management for fear of losing their libido and sexuality. Inability to satisfy and consummate marriage is a valid reason for the partner to find another wife (Muslims in Malaysia are legally allowed to have four wives). This fear of ultimately losing the husband to another woman due to lack of libido and loss of sexuality often causes women to refuse appropriate surgery. The recent availability of the levonorgestrel intra-uterine system (IUS) in Malaysia provides a suitable medical alternative to surgery in managing some of these patients. There is good evidence to suggest the effectiveness of the levonorgestrel IUS in the treatment of menorrhagia. The use of the levonorgestrel IUS in women whose cultural beliefs/misconceptions are not amenable to counselling, may help in the psychological preservation of their libido and sexuality.

Introduction: Teenage pregnancy is common and has become a key public health concern for all. This study aims to discover the meaning of lived experiences and to strategize in addressing the phenomenon from the previous or current unwed pregnant girls’ or young women’s perspective. Methods: A qualitative study was conducted among 10 girls or young women recruited during their stay at two shelters in Selangor but came from various state in Malay- sia; who have experienced becoming unwed mothers when they were between 10 to 19 years old. All participants gave informed consent. In-depth face-to-face interviews were conducted, audiotaped and transcribed. All quotes were encoded using Qualitative Data Analysis (QDA) Miner program. Data were analyzed using interpretative phe- nomenological analysis. Results: The themes emerged from the analyses; i) Trajectory of sexual activity, ii) struggles of motherhood to un-wed teenage mother. Most of these girls were pregnant due to consensual sexual intercourse although there were some refutes but their actions have led them for this to happen. They described how indirect relationship such as communication via telephone and the internet may have initiated the desire for sexual activity which led to a short first-time meeting and short term partnership, caused them to enact the sinful deed. They were overwhelmed with ambivalence feelings of wanting to terminate the pregnancy, abandon the newborn or to endure the journey of motherhood together with their ex-nuptial baby. Conclusion: The findings of this study showed that the strength of indirect relationship is able to evoke sexual desire that contributes to out-of-wedlock pregnancy. Max- imum support is needed from all; peers, parents, educators and the whole community structures.

Sexual desire includes complex motivation and drive. In the context of biological and cognitive- emotive state art of science, it is often a neglected field in medicine. In regard to the treatment, study on women's sexual function received less attention compared to the men's sexuality. In the past, this endeavor was relatively not well disseminated in the scientific community. Recently, there was a revolutionized surge of drug targets available to treat women with low sexual desire. It is timely to review the relevant biological approach, especially in the context of pharmacotherapy to understand this interesting clinical entity which was modulated by numerous interactive psychosocial inter-play and factors. The complex inter-play between numerous dimensional factors lends insights to understand the neural mechanism, i.e. the rewards centre pathway and its interaction with external psychosocialstimulus, e.g. relationship or other meaningful life events. The function of hormones, e.g. oxytocin or testosterone regulation was described. The role of neurotransmitters as reflected by the introduction of a molecule of flibenserin, a full agonist of the 5-HT1A and partial agonist of the D4 to treat premenopausal women with low sexual desire was deliberated. Based on this fundamental scientific core knowledge, we suggest an outline on know-how of introduction for sex therapy (i.e. "inner-self" and "outer-self") where the role of partner is narrated. Then, we also highlighted on the use of pharmacological agent as an adjunct scope of therapy, i.e. phosphodiasterase-5 (PDE-5) inhibitors and hormonal treatment in helping the patient with low sexual desire.

Yee A, Loh HS, Loh HH, Riahi S, Ng CG, Sulaiman AHB

Ann Gen Psychiatry, 2019;18:25.
PMID: 31649742 DOI: 10.1186/s12991-019-0249-z

Background: Methadone is an effective therapy for opiate dependence. However, one of the commonest side effects is sexual dysfunction among male patients. Buprenorphine is an alternative to methadone. This study aimed to compare sexual desire among opiate-dependent male patients on buprenorphine (BMT) and methadone maintenance therapy (MMT).
Methods: This cross-sectional study involved 126 male opiate-dependent patient who were tested for total testosterone (TT) and prolactin levels, and were interviewed and completed the Sexual Desire Inventory-2 (SDI-2), Malay language of International Index of Erectile Function (Mal-IIEF-15) and the Malay version of the self-rated Montgomery-Asberg Depression Rating Scale (MADRS-BM) questionnaires.
Results: There were 95 (75.4%) patients on MMT and 31 (24.6%) on BMT. Patients on MMT scored significantly lower in the sexual desire domain (Mal-IIEF-15 scores) (p

PMID: 23243445 DOI: 10.1155/2012/429268

Eurycoma longifolia is reputed as an aphrodisiac and remedy for decreased male libido. A randomized, double-blind, placebo controlled, parallel group study was carried out to investigate the clinical evidence of E. longifolia in men. The 12-week study in 109 men between 30 and 55 years of age consisted of either treatment of 300 mg of water extract of E. longifolia (Physta) or placebo. Primary endpoints were the Quality of Life investigated by SF-36 questionnaire and Sexual Well-Being investigated by International Index of Erectile Function (IIEF) and Sexual Health Questionnaires (SHQ); Seminal Fluid Analysis (SFA), fat mass and safety profiles. Repeated measures ANOVA analysis was used to compare changes in the endpoints. The E. longifolia (EL) group significantly improved in the domain Physical Functioning of SF-36, from baseline to week 12 compared to placebo (P = 0.006) and in between group at week 12 (P = 0.028). The EL group showed higher scores in the overall Erectile Function domain in IIEF (P < 0.001), sexual libido (14% by week 12), SFA- with sperm motility at 44.4%, and semen volume at 18.2% at the end of treatment. Subjects with BMI ≥ 25 kg/m(2) significantly improved in fat mass lost (P = 0.008). All safety parameters were comparable to placebo.

Hypersexuality As a Neuropsychiatric Disorder: The Neurobiology and Treatment Options

Asiff M, Sidi H, Masiran R, Kumar J, Das S, Hatta NH, et al.

Curr Drug Targets, 2018;19(12):1391-1401.

Hypersexuality refers to abnormally increased or extreme involvement in any sexual activity. It is clinically challenging, presents trans-diagnostically and there is extensive medical literature addressing the nosology, pathogenesis and neuropsychiatric aspects in this clinical syndrome. Classification includes deviant behaviours, diagnosable entities related to impulsivity, and obsessional phenomena. Some clinicians view an increase in sexual desire as 'normal' i.e. psychodynamic theorists consider it as egodefensive at times alleviating unconscious anxiety rooted in intrapsychic conflicts. We highlight hypersexuality as multi-dimensional involving an increase in sexual activity that is associated with distress and functional impairment. The aetiology of hypersexuality is multi-factorial with differential diagnoses that include major psychiatric disorders (e.g. bipolar disorder), adverse effects of treatments (e.g. levodopatreatment), substance-induced disorders (e.g. amphetamine substance use), neuropathological disorders (e.g. frontal lobe syndrome), among others. Numerous neurotransmitters are implicated in its pathogenesis, with dopamine and noradrenaline playing a crucial role in the neural reward pathways and emotionally- regulated limbic system neural circuits. The management of hypersexuality is determined by the principle of de causa effectu evanescent, if the causes are treated, the effect may disappear. We aim to review the role of pharmacological agents causing hypersexuality and centrally acting agents treating the associated underlying medical conditions. Bio-psycho-social determinants are pivotal in embracing the understanding and guiding management of this complex and multi-determined clinical syndrome.
