PURPOSE OF REVIEW: Sexual dysfunction is a frequent issue in patients with affective disorders, affecting its quality of life and posing challenges to the approach of these patients. RECENT FINDINGS: In recent years, human sexuality has attracted interest from the scientific community, and today we have a much deeper knowledge of the mechanisms involved in the sexual response. Paraphilias or sexual dysfunctions like low sexual desire, premature ejaculation, and erectile dysfunction, are frequent in affective disorders, and the frequency of each sexual problem varies according to the affective disorder...

Reproductive management of male donkeys employed for artificial breeding has been poorly studied. The aim of this study was to evaluate the effect of housing system, with the animals grouped together in a paddock or kept in individual boxes, on sexual behaviour, cortisol and testosterone concentration and seminal characteristics of adult male donkeys. The study included four Amiata donkey jacks (stallions) from which ejaculates, saliva and blood were collected during two distinct 3 weeks periods, one in the group and one in the box housing system...

Alpha linolenic acid (ALA) is integral component of cell membrane that protects the cell in stressful events and involves in many metabolic pathways. It was hypothesized that ALA have the ability to protect the structural and functional integrity of buffalo spermatozoa during freeze-thawing. Therefore, study was designed to evaluate ALA supplementation (0, 5, 10 and 20 ng/mL) in extender on freezability and in vivo fertility of buffalo bull spermatozoa. Semen from three adult Nili-Ravi buffalo bulls of similar age was collected with artificial vagina (42 °C) for five weeks (replicates; N = 30)...

Single layer centrifugation (SLC) through a colloid is a tool for selecting viable mammalian spermatozoa but has not been used previously for fresh dromedary camel sperm. Semen from six camels (2 ejaculates/male) was diluted 1:5 (v:v) or 1:10 (v:v) in a Tris-citrate-fructose buffer for mechanical liquefaction by gentle pipetting. Following liquefaction, semen was processed either by SLC or by centrifugation without a colloid (control). Total and progressive motilities, CASA kinematics, vitality and acrosome integrity (eosin-nigrosin) and plasma membrane integrity (Hypo-osmotic swelling test; HOST), and fertilizing ability in a heterologous assay (zona-free goat oocytes) were evaluated...

INTRODUCTION: Recent evidences demonstrated that male factor alone is responsible for about 30% cases of infertility. Human follicle-stimulating hormone (hFSH) has been introduced to increase sperm concentration, spermatogonial population, or both natural or assisted pregnancy rates (PRs) in oligozoospermic subjects with normal concentrations of gonadotropins. METHODS: Fifty infertile men affected by idiopathic azoospermia were enrolled in this study, after undergoing medical history, physical and clinical examination, baseline semen parameters and hormonal plasma concentrations...

Reproductive traits are complex, and desirable reproductive phenotypes, such as litter size or semen quality, are true polygenetic traits determined by multiple pathways. Each individual gene contributes to the overall variation in these traits, so genetic improvements can be achieved using conventional selection methodology. In the past, a pedigree-based-relationship matrix was used; this is now replaced by a combination of pedigree-based- and genomic-relationship matrices. The heritability of reproductive traits is low to moderate, so large-scale data recording is required to identify specific, selectable attributes...

The male gonadal tissue can be a sensitive target to the reprogramming effects of testosterone (T) during prenatal development. We have demonstrated that male lambs born to dams receiving T during pregnancy-a model system to the polycystic ovary syndrome (PCOS)-show a decreased number of germ cells early in life, and when adult, a reduced amount of sperm and ejaculate volume. These findings are a key to put attention to the male offspring of women bearing PCOS, as they are exposed to increased levels of androgen during pregnancy which can reprogram their reproductive outcome...

Elevated intracellular calcium concentration and oxidative damage are two major factors contributing to the poor fertility of cryopreserved spermatozoa. Regucalcin (RGN), also known as Senescence marker protein-30 (SMP-30), is a calcium-binding protein with multiple roles that include calcium homeostasis, anti-oxidative, anti-apoptosis, and anti-proliferation. In Drosophila, regucalcin is reportedly a putative cold-tolerance gene, and a cryoprotective role for regucalcin against intracellular calcium elevation and oxidative stress was reported in P19 cell lines...

Seminal plasma (SP) plays an important role in the motility, viability and maintenance of the fertilizing capacity of mammalian spermatozoa. This study is the first on brown bear (Ursus arctos) SP components, and has two main objectives: 1) to define the SP composition in bear ejaculate and 2) to identify variations in SP composition in relation to high and low levels of testosterone in serum during the breeding season. Forty-eight sperm samples from 30 sexually mature male brown bears (Ursus arctos) were obtained by electroejaculation, and their serum testosterone levels were assessed to sort the animals into 2 groups (high and low testosterone levels, threshold 5 ng/dl)...

The Indian red jungle fowl is a sub-species of the genus Gallus native to South Asia; facing high risks of extinction in its native habitat. During cryopreservation, permeable cryoprotectants like glycerol are usually employed and we previously showed encouraging results with 20% glycerol. Because bird spermatozoa contain very little intracellular water, the possibility of replacing an internal cryoprotectant by an external one is opened. In the present study, we tested the replacement of internal cryoprotectant glycerol by the external cryoprotectant Polyvinylpyrrolidone (PVP)...

BACKGROUND: Systematic studies on the association between men's sexual dysfunction (low sexual desire, ejaculation disorders, erectile dysfunctions, genital ulcers, testicular disorders, prostate cancer or sexually transmitted infections) and marital conflict are emerging. However, the coping strategies adopted by wives in such circumstances are not commonly reported in the literature. Male sexual functioning is vital to the marital relationship, lack of it can result in intolerable cohabitation or relationship breakdown, and could also cause infertility, infidelity, and arouse stigma in Nigeria...

Cryopreservation is used to preserve the spermatozoa; however, it leads to a reduction in sperm quality. L-carnitine (LC) influences sperm motility and preserves the sperm membrane and DNA integrity. The objectives of this study were to evaluate the protective effects of LC on the membrane integrity of normal human spermatozoa and compare it with pentoxifylline (PT) during cryopreservation. Thirty normal semen samples, prepared by swim-up procedure, were divided into three aliquots: a control without any treatment and two experimental aliquots that were incubated in PT or LC for 30 min...

Comparative analysis of the parameters of LPO, antioxidant defense (AOD), and the thiol/disulfide system was performed in fertile and infertile males of reproductive age carrying different genotypes of the glutathione system genes. Blood plasma, blood hemolysate, and ejaculate served as specimens for biochemical studies. A decrease in glutathione S-transferase activity was found in blood and ejaculate specimens from fertile and infertile carriers of nonfunctional GSTT1(0/0)/GSTM1(0/0) genotypes. In infertile carriers of nonfunctional GSTT1(0/0)/GSTM1(0/0) genotypes determining reduced glutathione S-transferase activity, a decrease in the concentration of low-molecular-weight cell antioxidant (reduced glutathione) and an increase in the concentration of secondary LPO products (TBA-reactive substances) were revealed...

Antioxidants are known to prevent the reactive oxygen species (ROS)-mediated peroxidative damage to the membrane lipids during hypothermic storage of mammalian spermatozoa. We hypothesized here that ROS also affect the lipid-protein interactions, thereby diminishing the membrane's integrity and proteins' anchorage to the bilayer. Antioxidants prevent these damages by scavenging the ROS. Ejaculates from Patanwadi rams were pooled after subjective evaluation and centrifuged using Percoll(®) . Sperm pellet was resuspended in soya lecithin-Tris-fructose diluent (400 × 10(6)  cells/ml) containing either antioxidants (100 IU/ml catalase + 10 mM reduced glutathione) or no antioxidant...
