Abstract
Sperm motility is an essential selection criteria by embryologists at the time of intracytoplasmic sperm injection (ICSI). One method of testing sperm viability is to induce sperm motility by increasing cyclic adenosine monophosphate (cAMP) levels by treating a semen sample with phosphodiesterase inhibitors (PDEIs), such as theophylline and pentoxifylline. It explores the implications of PDEI in medical care, reflecting on its effects in clinical settings and recognizing potential topics for future exploration. This analysis revealed that by incorporating stimulants that activate movements, the time it took to single out sperms was markedly reduced, and consequently, the sperms were safeguarded from a prolonged period of oxidative stress. Furthermore, theophylline was found to advance sperm motility, consequently resulting in several initially immobile spermatozoa displaying rapid progressive motility. Higher fertilization rate, cleavage rate, good quality embryos (grade I), and higher biochemical and clinical pregnancy rates were found with artificial sperm activation (ASA) using pentoxifylline and theophylline. This review emphasizes the need for more research to evaluate the drug's long-term safety and investigate the effects of theophylline and pentoxifylline on postfertilization parameters, such as embryo development, implantation, and pregnancy outcomes. These areas of investigation are important for understanding the complete impact of these agents and to ensure their safe and effective implementation in clinical practice.

Abstract
Pentoxifylline is a derivative of methylxanthine that affects sperm motility. Also, zinc is an antioxidant that is involved in the activation of antioxidant enzymes. This study aimed to evaluate the effect of co-administration of pentoxifylline, and zinc in men with idiopathic infertility. In the present study, men with idiopathic infertility were identified and randomly divided into four groups: pentoxifylline, zinc, pentoxifylline + zinc, and placebo. According to the grouping, the patients received pentoxifylline and zinc for 3 months. Then, sperm parameters, biochemical factors, reproductive hormones, inflammatory factors, and DNA damage were evaluated before and after intervention. Data analysis was performed using SPSS software. Pentoxifylline and zinc were significantly effective in improving biochemical parameters, inflammatory factors, concentration, and motility of sperm. Pentoxifylline did not affect sperm morphology and reproductive hormones. However, in the zinc and zinc + pentoxifylline groups, a significant increase in normal morphology and reproductive hormones was observed. In the pentoxifylline group, sperm DNA fragmentation increased significantly, while in the zinc and zinc + pentoxifylline group, DNA fragmentation reduced significantly. Because of the role of zinc in protecting sperm chromatin, it is recommended that zinc and pentoxifyllinebe prescribed simultaneously. Clinical trial code: NCT05156684.

Abstract
Enhancing sperm motility in vitro has immensely benefited assisted conception methods. Phosphodiesterases (PDE) break the second messenger cAMP, and therefore, inhibition of their catalytic activity enhances the sperm motility through maintaining cAMP homeostasis in sperm. In view of identifying the molecules that could inhibit PDE functioning in spermatozoa, we aimed to evaluate the phosphodiesterase inhibitors (PDEI) - xanthine derivatives - acefylline, dyphylline and proxyphylline to repurpose them for assisted reproductive technology. These are available in the market as pharmaceutical agents to treat mainly respiratory system diseases. Based on the structure guided in silico studies, we predicted that these molecules bind to the cAMP binding catalytic pocket of PDE enzymes, and further molecular dynamics simulation analysis indicated that these molecules form the stable complexes. Isothermal titration calorimetry studies revealed that acefylline has better affinity towards PDE4A, PDE4D and PDE10A, when compared to dyphylline and proxyphylline. In addition, ex vivo studies corroborated in vitro binding studies that acefylline has much superior sperm motility enhancement property on human ejaculated spermatozoa and mouse testicular spermatozoa compared to dyphylline and proxyphylline.Communicated by Ramaswamy H.

Abstract
Phosphodiesterase (PDE) inhibitors, such as pentoxifylline (PTX), are used as pharmacological agents to enhance sperm motility in assisted reproductive technology (ART), mainly to aid the selection of viable sperm in asthenozoospermic ejaculates and testicular spermatozoa, prior to intracytoplasmic sperm injection (ICSI). However, PTX is reported to induce premature acrosome reaction (AR) and, exert toxic effects on oocyte function and early embryo development. Additionally, in vitro binding studies as well as computational binding free energy (ΔGbind) suggest that PTX exhibits weak binding to sperm PDEs, indicating room for improvement. Aiming to reduce the adverse effects and to enhance the sperm motility, we designed and studied PTX analogues. Using structure-guided in silico approach and by considering the physico-chemical properties of the binding pocket of the PDEs, designed analogues of PTX. In silico assessments indicated that PTX analogues bind more tightly to PDEs and form stable complexes. Particularly, ex vivo evaluation of sperm treated with one of the PTX analogues (PTXm-1), showed comparable beneficial effect at much lower concentration-slower AR, higher DNA integrity and extended longevity of spermatozoa and superior embryo quality. PTXm-1 is proposed to be a better pharmacological agent for ART than PTX for sperm function enhancement.

Abstract
Application of nonspecific phosphodiesterases inhibitors, such as pentoxifylline (PTX), is a strategy utilised to aid sperm selection from immotile sperm samples prior to ICSI. No extensive studies have yet been performed to verify the safety of the clinical outcomes of ICSI after PTX administration. In this article, we summarise the data reported in the literature that assess the implication of in vitro usage of PTX on sperm parameters, as well as clinical outcomes during assisted male reproduction programme.

Abstract
This study investigated the effect of pentoxifylline (PTX) and Basal Medium Eagle (BME) on frozen-thawed goat spermatozoa. Immediately after initial examination of ejaculated semen, samples were pooled and reexamined for quality. Then, samples were divided into eight equal aliquots and diluted with a basic tris-extender containing PTX (3, 6, 9 mM) and BME (5 mM) to reach a final concentration of 25 × 109 and frozen. After 24 hr, the samples were individually thawed at 37°C for 30 s and evaluated for different characteristics. Obtained post-thaw results from Computer-Assisted Sperm Analysis indicate using of 3 and 6 mM PTX led significantly to an improvement in total motility, progressive motility and velocity characteristics of spermatozoa, except the beat/cross frequency (BCF) which indicated statistically no differences (p > .05) among control and treatments. Diluents prepared with BME (5 mM) and PTX alone (3 and 6 mM) improved significantly the membrane integrity-functionality, acrosome integrity and also hyaluronidase activity. Regarding recovery rate, the results showed significantly (p < .05) higher values for diluents containing 3 and 6 mM PTX compared to other groups. Malondialdehyde concentration exhibited also a significant difference (p < .05) in diluents supplemented with 5 mM BME, 3, 6 and 9 mM PTX, and mixture of 3 mM PTX and 5 mM BME which illustrate a similarity for active mitochondria, apoptotic-like and dead spermatozoa. Finally, the ratio of sperm chromatin dispersion stained spermatozoa presented significant differences (p < .05) among treatments in which the diluents added PTX alone demonstrated significantly lower values than control and extenders containing the mixtures of BME and PTX. In conclusion, the observation in this study indicates using of 3 and 6 mM PTX and BME alone may improve significantly (p < .05) the quality of cryopreserved goat spermatozoa.

Abstract
Intracytoplasmic sperm injection (ICSI) is frequently used to overcome severe deficits in semen quality. Concerns, however, are arising over its increasing use for non-male factor infertility. Moreover, increased risk of cardiovascular disease, congenital abnormalities, aneuploidies and childhood cancers have all been reported in the literature in relation to ICSI and it is possible that the quality of sperm chosen for injection may be an important factor in these unwanted outcomes. Given the wider adoption of ICSI to treat beyond the requirements of male infertility alone, research focussed on alternative methods to diagnose and treat the infertile couple is gaining increasing attention. This review focuses on the information available to date on the use of non-selective phosphodiesterase inhibitors (PDEI), specifically pentoxifylline (PF), caffeine (CF) and theophylline (TP) to stimulate sperm motility, thereby potentially reducing the need for ICSI in certain patient groups who may benefit from either expectant management or from a less stressful, minimally invasive and inexpensive treatment such as intrauterine insemination (IUI). The review focuses firstly on the mechanism of action of PDEI followed by treatment effects on sperm parameters such as motility and hyperactivated motility and sperm DNA integrity. Specific clinical implications are discussed that outline the potential role of PDEI in clinical practice and highlights areas in need of further research.

Abstract
PURPOSE Patients with Klinefelter syndrome (KS) who receive assisted reproductive technology (ART) treatment often experience poor pregnancy rates due to decreased fertilization, cleavage, and implantation rates and even an increased miscarriage rate. Mounting evidence from recent studies has shown that various technological advances and approaches could facilitate the success of ART treatment for KS patients. In this review, we summarize the methods for guiding KS patients during ART and for developing optimal strategies for preserving fertility, improving pregnancy rate and live birth rate, and avoiding the birth of KS infants. METHODS We searched PubMed and Google Scholar publications related to KS patients on topics of controlled ovarian stimulation protocols, sperm extraction, fertility preservation, gamete artificial activation, round spermatid injection (ROSI), and non-invasive prenatal screening (PGD) methods. RESULTS This review outlines the different ovulation-inducing treatments for female partners according to the individual sperm status in the KS patient. We further summarize the methods of retrieving sperm, storing, and freezing rare sperm. We reviewed different methods of gamete artificial activation and discussed the feasibility of ROSI for sterile KS patients who absolutely lack sperm. The activation of eggs in the process of intracytoplasmic sperm injection and non-invasive PGD are urgently needed to prevent the birth of KS infants. CONCLUSION The integrated strategies will pave the way for the establishment of ART treatment approaches and improve the clinical outcome for KS patients.

Abstract
RESEARCH QUESTION Does the adapted carrier Cryoplus improve the quality of cryopreserved spermatozoa compared with the use of conventional containers, and what is the effect of the adapted carrier on clinical outcomes? DESIGN Semen samples from 27 cases of oligozoospermia were used to investigate whether the adapted carrier improved cryopreserved sperm quality compared with the use of 0.25-ml straws and 2-ml cryogenic vials. Thirty testicular sperm samples were used to study the quality of testicular spermatozoa cryopreserved in the adapted carrier. The retrospective study included a further 104 men with azoospermia to investigate the clinical outcomes of testicular spermatozoa cryopreserved with the adapted carriers. Men with mostly obstructive azoospermia were included in this study. RESULTS The adapted carrier improved cryopreserved spermatozoa motility of semen samples compared with 2-ml cryogenic vials but not compared with 0.25-ml straws. No differences were found in cryopreserved sperm DNA fragmentation among the three carriers. Fertilization and good-quality embryo rates were similar in ICSI cycles using fresh or cryopreserved testicular spermatozoa. Additionally, no difference was evident between frozen-thawed embryo transfer cycles using fresh or cryopreserved testicular spermatozoa in clinical pregnancy, implantation, miscarriage, live birth rates or birth weight. CONCLUSIONS The adapted carrier improved the cryopreserved sperm motility compared with the effects of 2-ml cryogenic vials. The outcomes of intracytoplasmic sperm injection and frozen-thawed embryo transfer outcomes indicate that testicular spermatozoa cryopreserved using the adapted carrier is not inferior to fresh testicular spermatozoa. The use of the adapted carrier for cryopreserving human testicular spermatozoa especially from obstructive azoospermia is simple and effective.

Abstract
Platelets (PLTs) are classically used in the clinical setting to maintain hemostasis. Recent evidence supports important roles for PLTs in host inflammatory and immune responses, and PLT-rich plasma has been demonstrated to inhibit the growth of bacteria in vitro and in vivo; however, few studies have examined whether PLTs can inhibit bacterial growth directly, and related mechanisms have not been elucidated further. Accordingly, in this study, we evaluated the effects of PLTs on bacterial growth. We washed and purified PLTs from peripheral blood, then confirmed that PLTs significantly inhibited the growth of Staphylococcus aureus when cocultured in vitro. Moreover, PLTs damaged DNA and blocked cell division in S. aureus. During coculture, PLT-derived TGF-β1 was dramatically down-regulated compared with that in PLT culture alone, and the addition of TGF-β1 to the coculture system promoted the inhibition of PLTs on S. aureus. Analysis of a murine S. aureus infection model demonstrated that the depletion of PLTs exacerbated the severity of infection, whereas the transfusion of PLTs alleviated this infection. Our observations demonstrate that PLTs could directly inhibit the growth of S. aureus by damaging DNA and blockage cell division, and that PLT-derived TGF-β1 may play an important role in this machinery.-Xu, J., Yi, J., Zhang, H., Feng, F., Gu, S., Weng, L., Zhang, J., Chen, Y., An, N., Liu, Z., An, Q., Yin, W., Hu, X.
