Human exposure to intermediate frequency (IF) fields is increasing due to new applications such as electronic article surveillance systems, wireless power transfer and induction heating cookers. However, limited data is available on effects of IF magnetic fields (MF) on male fertility function. This study was conducted to assess possible effects on fertility indicators from exposure to IF MF. Male C57BL/6J mice were exposed continuously for 5 weeks to 7.5kHz MF at 12 and 120μT. Sperm cells from cauda epididymis were analysed for motility, total sperm counts, and head abnormalities...

Our objective was to assess the differential diagnostic value of classification of obstructive versus nonobstructive azoospermia by scrotal ultrasound. Forty patients with azoospermia were selected for our study (ages, 23-35; average, 29 ± 5.34 years). Patients were divided into the obstructive (17) or nonobstructive (23) azoospermia category. Twenty "healthy" volunteers were selected for the control group. We observed the testis, epididymis, and vas deferens in all subjects. Testicular volumes were calculated and compared with the control group for both obstructive and nonobstructive groups...

STUDY QUESTION: Does the deletion of adipose triglyceride lipase (Atgl) gene impair male fertility? SUMMARY ANSWER: The deletion of Atgl gene impaired male fertility but the effect was partially reversed by a low long chain triglyceride (TG) diet. WHAT IS KNOWN ALREADY: ATGL specifically hydrolyses long-chain fatty acid triglyceride (TG) to diacylglycerol and a high level of expression of ATGL in testes has been reported. However, the role of ATGL in male fertility is unknown...

Hematospermia or hemospermia is defined as the presence of blood in ejaculate. The true prevalence of the condition is unknown because many cases escape the patient's notice, and remain unrecognized and unreported. There are two main aims in the patient evaluation: first, to ensure that there is no specific condition that is treatable; second, to reassure the patient's parents that no causative factor is present. Many physicians are unfamiliar with this disorder and this forms the basis for our current review...

Spermatogenesis is a complex and highly regulated process. The ability of spermatozoa to perform its function depends on multiple physiological and genetic factors that are not fully understood. Notably, due to lack of transcriptional and translational activity in spermatozoa, posttranslational modifications (PTMs) play key roles in determining their viability. PTMs not only confer structural changes in the proteome of the spermatozoa cells, but also increase the diversity of the proteome and introduce specific modifications that could be translated into functional changes in the affected spermatozoa...

Polyorchidism is a very rare genitourinary anomaly defined with the presence of more than two testicles. Polyorchidism is associated up to 40% with undescended testicles. The present report is about an incidentally detected triorchidism case with unilateral, one atrophic undescended double testicles. A 4-year-old child, diagnosed with undescended left testicle revealed during orchiopexy polyorchidism with distinct epididymis and vas deferens. Whereas one of the testicles was in regular size; the other two were atrophic...

Transplantation of testicular cells and tissues has been studied for the investigation of immunology of the testis, which is an immunologically privileged organ. However, reports of transplant of the testis at organ level have been extremely limited because of technical difficulties of the orthotopic testis transplantation (OTT) in experimental animals. In the present study, we developed a new and simple model of the heterotopic testis transplantation (HTT), which is donor testis transplantation into the cervical region of recipients, in a syngeneic model in rats [donor Lewis (LEW) graft to LEW recipient]...

Sarcoidosis is an inflammatory disease with unknown cause characterized by noncaseating granuloma formations. It may present with bilateral hilar lymphadenopathy, skin lesions, eye, and musculoskeletal system involvement. Rare involvement of the genital organs (prostate, testis, epididymis) has also been reported. However, penile involvement is observed quite rare. In this paper, we report a patient with penile mass who was diagnosed with sarcoidosis on the basis of the laboratory, radiological, and pathological investigations...

Acquisition of sperm capacitation post-ejaculation into the female reproductive tract is an essential step in the fertilization process. Accordingly, during in vitro fertilization, successful fertilization requires the induction of capacitation in epididymis-retrieved sperm. To date, many candidate substances have been considered as capacitation inducers; however, there are no reports on the efficiency of inducing sperm capacitation among the diverse inducers. Therefore, we attempted to determine the inducer with the best capacitation in inbred mouse sperm by comparing the capacitation performance of a variety of inducers and the percentage of in vitro fertilization-generated zygotes...

Zika virus (ZIKV) can be transmitted via mosquito bite or sexual contact. Using mice that lack the type I interferon receptor we examine sexual transmission of ZIKV. Electron microscopy analyses showed association of virions with developing sperm within testes as well as with mature sperm within epididymis. When ZIKV-infected male mice were mated with naïve female mice, the weight of fetuses at embryonic day 18.5 (E18.5) was significantly reduced compared with the control group. Additionally, we found ocular deformities in a minority of the fetuses...

Host defense peptides (HDPs) are an important component of the innate immune system and possess direct antimicrobial and immunomodulatory activities. Dietary regulation of HDPs synthesis has emerged as a novel non-antibiotic approach to combat pathogen infection. There are species- and tissue-dependent characteristics of the regulation and mechanism of HDPs. In this study, we investigated whether the histone deacetylase inhibitor (HDACi) sodium butyrate (NaB) could induce HDP expression and the mechanism underlying NaB-regulated HDP expression in PK-15 cells...

The paratestis (PT) is defined by the testicular tunics, epididymis, spermatic cord, rete testis, and embryonic remnants. It gives rise to a large diversity of pathologies, including those of soft tissue, which may prompt orchiectomy. We performed a 17-year search of our database for orchiectomies for a PT soft-tissue mass. In a total of 4741 orchiectomy specimens, 138 orchiectomies were performed for primary neoplastic or nonneoplastic masses of the PT soft tissue or had an incidental PT soft-tissue mass. Of these, 65...

Spermatozoa retrieved from the testis of men with high levels of sperm DNA fragmentation (SDF) in the neat semen tend to have better DNA quality. Given the negative impact of SDF on the outcomes of Assisted Reproductive Technology (ART), an increased interest has emerged about the use of testicular sperm for intracytoplasmic sperm injection (Testi-ICSI). In this article, we used a SWOT (strengths, weaknesses, opportunities, and threats) analysis to summarize the advantages and drawbacks of this intervention...

A 5-month-old boy presented with right scrotal swelling. Color Doppler ultrasonography showed an encapsulated hypoechoic lesion with surrounding hyperemia in the right tail of the epididymis. We performed surgical exploration of the scrotum because it was not considered to be a typical epididymitis. During the operation, we aspirated pus from his right epididymis through a needle by referring to the color Doppler findings. This is the first case of epididymal abscess in an infant to be successfully diagnosed and treated with needle aspiration...
