We performed this study to evaluate the clinical outcomes of microdissection testicular sperm extraction-intracytoplasmic sperm injection (micro-TESE-ICSI) treatment that used fresh or cryopreserved sperm in patients with nonobstructive azoospermia (NOA). A total of 338 NOA patients with 344 consecutive cycles received treatment in the reproductive medicine center of Peking University Third Hospital in Beijing, China, from January 2014 to December 2017. Fresh oocytes and fresh sperm were used in 222 patients with 234 cycles (Group A). Fresh oocytes and cryopreserved sperm were used in 116 patients with 110 cycles (Group B). We compared patient characteristics, embryonic development, and pregnancy outcomes between Groups A and B. There was no statistical difference in the patient characteristics, and no differences were observed with fertilization or quality embryo rates between Groups A and B. The rates of clinical pregnancy and live birth were both higher for Group A than those for Group B (both P < 0.05). In conclusion, fresh testicular sperm appears to produce better ICSI outcomes than cryopreserved testicular sperm in patients with NOA.

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.

In Brief: Lipid homeostasis is vital for maintaining testicular function and male fertility, but the specific contributions of lipid-regulating enzymes remain unclear. This study shows that DGKη, although highly expressed in the testis, is not essential for spermatogenesis but modulates testicular lipid metabolism in response to dietary conditions.
Abstract: Diacylglycerol kinase eta (DGKη), encoded by the Dgkh gene, catalyzes the phosphorylation of diacylglycerol to phosphatidic acid, both of which are key lipid second messengers.

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.

Background: Obesity is associated with hormonal imbalance, increased oxidative stress, and inflammation in the testis. These conditions adversely affect sperm quality, leading to impaired male fertility. Therefore, therapeutic interventions to counteract the adverse effects of obesity are crucial.
