Article Abstract
With changes in the modes of life and work, infertility is becoming a serious international problem. The incidence of infertility is 10－15% of the couples of childbearing age in China and is increasing year by year, and 30－50% of the cases are related to male factors. Trace elements refer to the chemical elements that account for less than 1/10,000 of the total weight of the human body, of which less than 100 mg is required per person per day. They are important biochemical components in the semen. Trace elements are essential for normal spermatogenesis, sperm maturation and capacitation, and maintenance of normal sperm function, though sperm quality can be affected by genetic, epigenetic, environmental and lifestyle-related factors. This focuses on the latest progress in the studies of the effects of trace elements on sperm quality.

Di-isobutyl phthalate (DiBP), a member of the phthalate esters, is frequently used in manufacturing consumer and industrial products as plasticizer to improve durability and flexibility. Despite much research, little is known about the direct mechanisms by which DiBP harms the male reproductive system. In the present study, a male ICR mice model was developed to investigate the reproductive effect and mechanism of DiBP exposure, followed by transcriptomics, non-targeted metabolome, and 16S rDNA sequencing accordingly.

Purpose Of Review: Infertility affects approximately 15% of couples, with male factors implicated in more than 50% of cases. Concerns over declining semen quality - evidenced by a more than 50% drop in sperm concentration over four decades - have triggered investigation into modifiable lifestyle and environmental factors. This review summarizes recent evidence on exposures that negatively impact male fertility.

Background: Varicocele is a common, correctable cause of male infertility, often associated with impaired spermatogenesis. Microsurgical subinguinal varicocelectomy is considered the gold standard for varicocele repair, with documented benefits on semen quality, particularly sperm count.
Objective: The objective of this study was to evaluate the effect of microsurgical varicocelectomy on sperm count in infertile men diagnosed with clinical varicocele.

Background: Methotrexate (MTX), a folate antagonist, is widely used in the treatment of tumors and autoimmune diseases such as rheumatoid arthritis (RA), due to its antiproliferative, antimetabolic, and potent anti-inflammatory properties. However, high-dose or long-term use of MTX can result in toxicity to the gastrointestinal, hemopoietic, and reproductive tissues. Yunpi Jiedu Tongluo Qushi Decoction (YJT), an effective Chinese herbal formula, is utilized in RA treatment to mitigate the toxic and side effect of MTX.
