BACKGROUND: Challenging conditions experienced early in life, such as a restricted diet, can detrimentally affect key life-history traits. Individuals can reduce these costs by delaying their sexual maturation, albeit at the price of the later onset of breeding, to eventually reach the same adult size as individuals that grow up in a benevolent environment. Delayed maturation can, however, still lead to other detrimental morphological and physiological changes that become apparent later in adulthood (e...

DNA compaction with protamines in sperm is essential for successful fertilization. However, a portion of sperm chromatin remains less tightly packed with histones, which genomic location and function remain unclear. We extracted and sequenced histone-associated DNA from sperm of nine ejaculates from three bulls. We found that the fraction of retained histones varied between samples but the variance was similar between samples from the same and different individuals. The most conserved regions showed similar abundance across all samples, while in other regions their presence correlated with the size of histone fraction...

BACKGROUND: Cryptozoospermia (CO) is a situation in which spermatozoa cannot be observed in a fresh semen sample unless an extended centrifugation and microscopic search are performed. CO patients are suggested to use only intracytoplasmic sperm injection (ICSI) as infertility treatment. But still there is debate about the choice of sperm source in cryptozoospermic men candidate for ICSI. OBJECTIVES: This study was conducted to evaluate fertility outcomes in men with idiopathic cryptozoospermia who were treated using ICSI with freshly ejaculated sperm and testis sperm extraction (TESE) or percutaneous epididymal sperm aspiration (PESA)...

Semen cryopreservation is affected by individual differences and use of clones animal from the same source is the main tool to eliminate genetic variation. Among many nutrients that are necessary for fertility, essential fatty acids and antioxidants are vital for production of healthy sperm by improving sperm membrane integrity and protecting sperm from oxidative stress. The goal of the current study was to investigate whether a flax seed oil or/and Vitamin E dietary supplementation could improve semen quality of cloned bucks following semen cryopreservation...

Tramadol is a well-known and effective analgesic. Recently it was shown that tramadol is also effective in human premature ejaculation. The inhibitory effect of tramadol on the ejaculation latency is probably due to its mechanism of action as a μ-opioid receptor agonist and noradrenaline/serotonin (5-HT) reuptake inhibitor. In order to test this speculation, we tested several doses of tramadol in a rat model of male sexual behavior and investigated two types of drugs interfering with the μ-opioid and the 5-HT system...

In butterflies, male reproductive success is highly related to the quality and the size of the spermatophore transferred to the female. The spermatophore is a capsule produced by the male during copulation, which in many species contains sperm in addition to a nuptial gift, and which is digested by the female after copulation. The nuptial gift may contribute to egg production and offspring quality, and in some cases also to female body maintenance. The production of the spermatophore, however, represents a cost for the male and, in polyandrous species, ejaculates are sometimes allocated adaptively across matings...

Retroperitoneal lymphnode dissection (RPLND) is a fundamental surgical step in the treatment of testicular cancer. Nowadays primary RPLND has partially lost its role in favour of active surveillance (for low risk stage I disease) and short cycle chemotherapy in non-seminomatous germ cell tumour (NSGCT). Conversely, postchemotherapy-RPLND (PC-RPLND) remains the standard treatment for residual masses after chemotherapy. In consideration of curability rate of testicular cancer and the life expectancy of testicular cancer survivors the identification and the prevention of andrological complications became fundamental...

The Indochinese leopard (Panthera pardus delacouri) population, included in CITES Appendix I, has been declining for decades. Proper gamete preservation condition is critical for breeding programme management using artificial insemination or in vitro fertilization (IVF). The present study aimed at investigating the impact of post-thawing treatment of leopard semen with extracellular adenosine 5'-triphosphate (ATPe) on sperm quality (including morphological traits and ability to fertilize an oocyte). Semen from six adult male leopards was collected by electroejaculation (one ejaculation per cat)...

Spermatogenesis is an androgen-regulated process that depends on the action of androgen receptor (AR). Sperm production may be affected in men treated for testicular cancer (TC), and it is important to identify the factors influencing the timing of spermatogenesis recovery following cancer treatment. It is known that the CAG and GGN repeat numbers affect the activity of the AR; therefore, the aim of this study is to investigate if the CAG and GGN polymorphisms in the AR gene predict recovery of sperm production after TC treatment...

INTRODUCTION: Tramadol exhibits an effect profile similar to that of opioid agonists, and tramadol abuse seems to be a problem for a number of countries. The relationship between tramadol and sexual function appears to be controversial. Men with premature ejaculation (PE) may benefit from taking tramadol off label; however, these patients live "on a knife's edge" and are exquisitely sensitive to develop other sexual dysfunctions. AIM: To review the literature regarding the problem of tramadol abuse and its relationship with sexual function...
