A global perspective: characteristics of infertility-related randomized clinical trials.

Background: Infertility is a prevalent global condition, and emerging reproductive technologies may enhance its evaluation and treatment. Understanding the current features of randomized clinical trials in infertility is crucial for improving study design and ensuring the translation of results for patient benefits.

Objectives: To investigate the primary characteristics of randomized clinical trials related to infertility and areas where require improvement.

The protective effects and underlying mechanisms of dapagliflozin on diabetes-induced testicular dysfunction.

Male diabetic individuals present a marked impairment in fertility; however, knowledge regarding the pathogenic mechanisms and therapeutic strategies is unsatisfactory. The new hypoglycemic drug dapagliflozin has shown certain benefits, such as decreasing the risk of cardiovascular and renal events in patients with diabetes. Even so, until now, the effects and underlying mechanisms of dapagliflozin on diabetic male infertility have awaited clarification.

Therapeutic Effects of Xianlu Oral Solution on Rats with Oligoasthenozoospermia through Alleviating Apoptosis and Oxidative Stress.

Idiopathic oligoasthenozoospermia (iOAZS) is one of the major causes of male infertility, and the ideal therapies for iOAZS have not been established yet. Traditional Chinese medicine (TCM), including Xianlu oral solution (XL), has been widely used as an adjunct treatment for male infertility in the clinic. However, the underlying mechanisms of XL treatment on iOAZS are still not known.

Contribution of TRESK two-pore domain potassium channel to bone cancer-induced spontaneous pain and evoked cutaneous pain in rats.

Cancer-associated pain is debilitating. However, the mechanism underlying cancer-induced spontaneous pain and evoked pain remains unclear. Here, using behavioral tests with immunofluorescent staining, overexpression, and knockdown of TRESK methods, we found an extensive distribution of TRESK potassium channel on both CGRP and IB4 nerve fibers in the hindpaw skin, on CGRP nerve fibers in the tibial periosteum which lacks IB4 fibers innervation, and on CGRP and IB4 dorsal root ganglion (DRG) neurons in rats.

Roles of CatSper channels in the pathogenesis of asthenozoospermia and the therapeutic effects of acupuncture-like treatment on asthenozoospermia.

Idiopathic asthenozoospermia (iAZS) is one of the major causes of male infertility and has no effective therapeutic treatment. Understanding the potential mechanisms that cause it may be helpful in seeking novel targets and treatment strategies for overcoming the problem of low sperm motility in iAZS individuals. Computer-assisted semen analysis (CASA) was utilized to assess the sperm motility.

Contribution of microglial reaction to increased nociceptive responses in high-fat-diet (HFD)-induced obesity in male mice.

The progressive increase in the prevalence of obesity in the population can result in increased healthcare costs and demands. Recent studies have revealed a positive correlation between pain and obesity, although the underlying mechanisms still remain unknown. Here, we aimed to clarify the role of microglia in altered pain behaviors induced by high-fat diet (HFD) in male mice.

Decreased abundance of TRESK two-pore domain potassium channels in sensory neurons underlies the pain associated with bone metastasis.

Cancer-associated pain is debilitating. Understanding the mechanisms that cause it can inform drug development that may improve quality of life in patients. Here, we found that the reduced abundance of potassium channels called TRESK in dorsal root ganglion (DRG) neurons sensitized nociceptive sensory neurons and cancer-associated pain.

Activation of CRF/CRFR1 signaling in the basolateral nucleus of the amygdala contributes to chronic forced swim-induced depressive-like behaviors in rats.

The basolateral nucleus of the amygdala (BLA) plays a key role in processing stressful events and affective disorders. Previously we have documented that exposure of chronic forced swim (FS) to rats produces a depressive-like behavior and that sensitization of BLA neurons is involved in this process. In the present study, we demonstrated that chronic FS stress (CFSS) could activate corticotropin-releasing factor (CRF)/CRF receptor type 1 (CRFR1) signaling in the BLA, and blockade of CRF/CRFR1 signaling by intra-BLA injection of NBI27914 (NBI), a selective CRFR1 antagonist, could prevent the CFSS-induced depressive-like behaviors in rats, indicating that activation of CRF/CRFR1 signaling in the BLA is required for CFSS-induced depression.

[Experimental Study for the Treatment of Asthenozoospermia by Electroacupuncture in Rats].

Objective: To investigate the effects of different electroacupuncture (EA) parameters for the treatment of asthenozoospermia in rats.

Methods: One hundred and five male Sprague-Dawley rats were randomly divided into 2 Hz-EA treatment daily in 3 d group (=9), sham-EA group (=10), model group (=10); 2 Hz-EA treatment every other day in 5 d group, sham-EA group, model group (8 rats in each group); 2 Hz-EA treatment every other day in 9 d group, sham-EA group, model group (10 rats in each group); 100 Hz-EA treatment every other day in 9 d group (=7), sham-EA group (=8), model group (=7). Asthenozoospermia model was established by intragastric administration of ornidazole (ORN,400 mg·kg·d) once daily till the end of treatment.

BDNF Contributes to Spinal Long-Term Potentiation and Mechanical Hypersensitivity Via Fyn-Mediated Phosphorylation of NMDA Receptor GluN2B Subunit at Tyrosine 1472 in Rats Following Spinal Nerve Ligation.

Previously we have demonstrated that brain-derived neurotrophic factor (BDNF) contributes to spinal long-term potentiation (LTP) and pain hypersensitivity through activation of GluN2B-containing N-methyl-D-aspartate (GluN2B-NMDA) receptors in rats following spinal nerve ligation (SNL). However, the molecular mechanisms by which BDNF impacts upon GluN2B-NMDA receptors and spinal LTP still remain unclear. In this study, we first documented that Fyn kinase-mediated phosphorylation of GluN2B subunit at tyrosine 1472 (pGluN2B) was involved in BDNF-induced spinal LTP and pain hypersensitivity in intact rats.

[Transcutaneous electrical acupoint stimulation for asthenozoospermia].

Objective: To study the effect of transcutaneous electrical acupoint stimulation (TEAS) in the treatment of asthenozoospermia.

Methods: We randomly divided 72 asthenozoospermia patients into a 2 Hz TEAS (n = 29), a 100 Hz TEAS (n = 20), and a blank control group (n = 23), those in the former two groups treated by 30 minutes of TEAS at 2 Hz and 100 Hz respectively, applied to the acupoints of bilateral Shenshu, left Zusanli, and Guanyuan, once a day for 60 days, while those in the blank control group left untreated. Using computer-assisted sperm analysis (CASA), we examined sperm concentration and motility as well as the percentages of grade a and grade a+b sperm in different groups of the patients.

Sensitization of neurons in the central nucleus of the amygdala via the decreased GABAergic inhibition contributes to the development of neuropathic pain-related anxiety-like behaviors in rats.

Background: Despite high prevalence of anxiety accompanying with chronic pain, the mechanisms underlying pain-related anxiety are largely unknown. With its well-documented role in pain and emotion processing, the amygdala may act as a key player in pathogenesis of neuropathic pain-related anxiety. Pain-related plasticity and sensitization of CeA (central nucleus of the amygdala) neurons have been shown in several models of chronic pain.
