The sexual transmission of viruses is responsible for the spread of multiple infectious diseases. Although the HIV/AIDS pandemic remains fueled by sexual contacts with infected semen, the origin of virus in semen is still unknown. In a substantial number of HIV- infected men, viral strains present in semen differ from the ones in blood, suggesting that HIV is locally produced within the genital tract. Such local production may be responsible for the persistence of HIV in semen despite effective antiretroviral therapy...

We report the case of a 46-year-old Chinese male patient who visited our clinic complaining of infertility. Semen analysis revealed azoospermia, and azoospermia factor c region partial deletion (b1/b3) was detected using Y chromosome microdeletion analysis. Testicular sperm extraction was performed after genetic counseling. The bilateral ductus deferens and a portion of the epididymis were absent, whereas the remaining epididymis was expanded. Motile intratesticular spermatozoa were successfully extracted from the seminiferous tubule...

Imposex is a disorder caused by organotins, mainly tributyltin, which results in the appearance of male sexual characteristics in females of gastropod mollusks. The main objective of this work was to make a critical analysis of the relationship between imposex and butyltin body burdens in Nucella lapillus and Nassarius reticulatus. Specifically, this study evaluates possible additive effects among butyltins, proposes scales of effects based on robust statistical criteria as alternatives to existing ones and defines the body burdens of TBT in N...

Congenital absence of the vas deferens (CAVD) is a relatively rare anomaly that may contribute to male infertility. The aim of this study was to evaluate the clinical features of patients with CAVD and to emphasise some pathological conditions that may be detected during the infertility work-up or follow-up of these patients. The charts of 150 males with the diagnosis of CAVD were evaluated retrospectively. The demographic characteristics, reasons for attendance, the way of diagnosis, interventions for infertility before and after attendance, physical examination findings, reproductive hormone levels, semen analysis results, genetical analysis results and resultant live birth events were all included in the study...

As a non-threatened hystricognath rodent species, Spix's yellow-toothed cavies can be used as a model for the development of assisted reproductive techniques for the conservation of closely related species. The objective was to establish a functional protocol for cryopreservation of epididymal sperm from these cavies. Twelve sexually mature males, ∼2 y old and weighing ∼300 g, were euthanized. Sperm were recovered by retrograde flushing of the vas deferens and cauda epididymis with Tris extender. Thereafter, sperm were extended in Tris plus 20% egg yolk, with 3%, 6% or 9% glycerol or dimethyl sulfoxide (DMSO), placed in 0...

We have investigated the cardiac and pressor responses to (±)-ephedrine and (-)-ephedrine in pentobarbitone anaesthetized male wistar rats. The tachycardiac responses to (±)- and (-)-ephedrine were similar, but pressor responses to (-)-ephedrine (10 mg/kg) were significantly greater than those to (±)-ephedrine, and for both, the pressor response was followed by a small depressor response. Sympathectomy did not affect pressor responses, but significantly increased the later depressor response to both compounds...

Molecular investigations were performed in order to determine the major characteristics of voltage-gated Na+ channel β-subunits in mouse vas deferens. The use of real-time quantitative PCR showed that the expression of Scn1b was significantly higher than that of other β-subunit genes (Scn2b - Scn4b). Immunoreactivity of Scn1b proteins was also detected in the inner circular and outer longitudinal smooth muscle of mouse vas deferens. In whole-cell recordings, the actions of 4,9-anhydroTTX on voltage-gated Na+ current peak amplitude in myocytes (i...

Varicocele is a common abnormality, but the conventional microsurgical subinguinal varicocelectomy (CMSV) has some disadvantages. We invented Modified Inguinal Microscope-Assisted Varicocelectomy (MIMV) under local anesthesia. This study aims to evaluate MIMV by comparing it to CMSV in operating duration, time to return to normal activity, postoperative complications, achievement of natural pregnancy and improvement of semen quality for patients with infertility, pain score for those with scrotal pain, and so on...

The fine structure of the seminal vesicle and reproductive accessory glands was investigated in Bittacidae of Mecoptera using light and transmission electron microscopy. The male reproductive system of Bittacidae mainly consists of a pair of testes, a pair of vasa deferentia, and an ejaculatory sac. The vas deferens is greatly expanded for its middle and medio-posterior parts to form a well-developed seminal vesicle. The seminal vesicle is composed of layers of developed muscles and a mono-layered epithelium surrounding the small central lumen...

α1 -Adrenoceptor (α1 -AR) antagonists are considered to be the most effective monotherapy agents for lower urinary tract symptoms associated with benign prostatic hyperplasia (LUTS/BPH). In this study, we synthesized compounds 2-17, which are novel piperazine derivatives that contain methyl phenylacetate. We then evaluated the vasodilatory activities of these compounds. Among them, we found that compounds 2, 7, 12, which contain 2-OCH3 , 2-CH3 or 2, 5-CH3 , respectively, exhibited potent α1 -blocking activity similar to protype drug naftopidil (1)...

Polyorchidism is a rare condition usually incidentally discovered in young patients investigated with ultrasound for unrelated reasons. It is characterized by the presence of unilateral or, rarely, bilateral supernumerary testes which, depending on the type of polyorchidism, may have their own epididymis and vas deferens. Ultrasound, including B-mode and color Doppler technique, represents the primary imaging modality for the evaluation of scrotal diseases, including the characterization of supernumerary testes, which normally appear identical to the ipsilateral testicular parenchyma on every ultrasonographic technique performed...

Prostatic utricle cyst is a rare congenital anomaly. Symptomatic cysts require treatment. Surgical excision is the treatment of choice, but is challenging due to close proximity to vas deferens, ejaculatory ducts, bladder, prostate, rectum and pelvic nerves. Complications include rectal injury, ureteral injury, impotence, infertility and faecal incontinence. We here report a rare complication in which bladder was accidentally removed during laparoscopic excision of prostatic utricle cyst. To best of our knowledge such a complication has never been reported previously...

In a number of marine animals, sperm serine proteases are important for fertilization. Penaeus monodon sperm require trypsin-like activity for a complete acrosome reaction, which exclusively occurs in sperm residing in the female thelycum. In this study, a complete cDNA sequence of reproductive tract-related Serine protease inhibitor (rrPmserpin) was identified. The longest open reading frame was composed of 1,366 nucleotides encoding 402 amino acids with a predicted pI of 6.86 and molecular mass of 44.88 kDa...

REVIEW
Ibrahim A Abdel-Hamid, Omar I Ali
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...
