Purpose Of Review: Male factor infertility is a complex and multifaceted problem facing the modern urologist and is identified in 30-40% of infertile couples. This review focuses on the use of ultrasound, as an adjunct screening tool, in the initial evaluation of male infertility.
Recent Findings: Access to male reproductive urologist for assessment of male infertility is limited and about a quarter of infertile couples do not complete the male component in their infertility assessment. Ultrasound evaluation of the infertile male is low-cost and non-invasive and helps uncover underlying pathologies that may be missed during the initial assessment. The addition of ultrasound allows the physician to accurately assess testicular anatomy and dimensions, as well as vascular environments, which may help guide treatment decisions. Scrotal ultrasound evaluation, in conjunction with a semen analysis and as an adjunct to physical exam, can be offered in the initial assessment of men who present for infertility consultation given its low cost, non-invasive nature, and ability to detect and discriminate between various etiologies of male infertility. Further, when directed by physical exam and semen analysis findings, it provides a valuable tool to select men for referral to a reproductive urologist, especially for infertile couples who are only screened by reproductive endocrinologists and female infertility specialists.

Background: Chinese cabbage is a cross-pollinated crop with remarkable heterosis, and male-sterile line is an important mean to produce its hybrids. In this study, a male-sterile mutant msm7 was isolated from a Chinese cabbage DH line 'FT' by using EMS-mutagenesis.
Results: Compared with the wild-type 'FT', the anthers of mutant msm7 were completely aborted, accompanied by the defects in leaf and petal development.

As global change threatens avian biodiversity, understanding species responses to environmental perturbations due to radiation emitted by enormous increase in the application of wireless communication is very urgent. The study investigates the effect of MW radiation on redox balance, stress level, male fertility and the efficacy of Withania somnifera (WS) root extract (100 mg/kg body weight) orally administered in 8 weeks old mature male Japanese quail exposed to 2.4 GHz MW radiation for 2 h/day for 30 days with power density = 0.

Purpose: Infertility is defined as the inability to conceive after 1 year of unprotected intercourse, affecting approximately 15-20% of couples in Western countries. It is a shared problem within the couple; when the main issue lies with one of the partners, it is preferable to refer to "male factor" or "female factor" infertility rather than simply male or female infertility. Despite male factor infertility accounting for half of all couple infertility cases, the clinical approach to the male partner is not uniformly standardized across international guidelines.

Infertility affects 10-15% of couples worldwide, with male factors accounting for half of cases. Environmental, behavioral, and genetic problems contribute to spermatogenic failure in 30% of idiopathic male infertility cases. Other factors, such as oxidative stress (OS), cause impaired spermatogenesis, abnormal sperm morphology, and reduced motility, eventually triggering male infertility.

The production of spermatozoa, a process known as spermatogenesis, is primarily controlled by follicle-stimulating hormone (FSH) and luteinizing hormone (LH)-driven testosterone. LH acts on the Leydig cells, stimulating steroid production, predominantly testosterone, and activating critical inter-related spermatogenesis regulatory pathways. Despite evidence that exogenous gonadotropins containing LH activity can effectively restore spermatogenesis in males with hypogonadotropic hypogonadism, the use of these drugs to treat other forms of male infertility is the subject of an ongoing debate.
