Pentoxifylline treatment as a safe method for selecting viable testicular spermatozoa before cryopreservation of a small numbers of spermatozoa in azoospermia individuals. Arch Ital Urol Androl 2024; 96:12525. [PMID: 38934523 DOI: 10.4081/aiua.2024.12525] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2024] [Accepted: 04/13/2024] [Indexed: 06/28/2024] Open
Abstract
BACKGROUND Single sperm cryopreservation (SSC) is a specific technique especially used in individuals with small numbers of sperm who suffered from non-obstructive azoospermia (NOA). Testicular specimens possess poor motility and low population of viable spermatozoa. Therefore, sperm selection methods such as applying pentoxifylline (PTX) may improve motility in these cases. The main aim of this study was to evaluate the protective effects of PTX on testicular spermatozoa before and after performing SSC. METHODS Thirty testicular samples were obtained from men with azoospermia. This study was conducted in two phases. Phase 1 evaluated the effect of PTX for sperm selection before SSC. Twenty testicular samples were divided to two experimental groups: SSC without (I) and with PTX treatment (II). For PTX treatment spermatozoa were incubated with PTX at 37°C for 30 min and only motile spermatozoa were selected for SSC. In phase 2, ten testicular samples were cryopreserved with SSC and warming procedure was carried out in droplet with and without PTX. Motility and viability rates, morphology by motile sperm organelle morphology examination (MSOME), DNA fragmentation by sperm chromatin dispersion test (SCD) and mitochondrial membrane potential (MMP) were evaluated. RESULTS In phase 1, post warm motility rate was higher in PTX exposed group compared to the unexposed group (25.6 ± 8.13 vs. 0.85 ± 2.1) (p > 0.00). Recovery rate, viability and morphology were not significantly different between groups. DNA integrity and MMP were also similar between both groups. In phase 2 although motility increased in PTX group compared to without PTX group (29.30 ± 12.73 vs. 1.90 ± 2.64) (p > 0.00), the viability rate was not different (70.40 ± 12.12 vs. 65.30 ± 11.87). All above mentioned parameters were similar between the two SSC groups. CONCLUSIONS Supplementation of testicular spermatozoa with PTX before cryopreservation increases motility and did not have adverse effects on viability, morphology, DNA integrity and MMP. PTX could be used as sperm selection method before single sperm cryopreservation, but PTX could not maintain motile the most of viable testicular sperms.

Abstract
BACKGROUND Spermatozoa retrieved from the testis and epididymis are deprived of the beneficial effects of seminal fluid. Thus applying an artificial medium with normal seminal fluid characteristics, known as artificial seminal fluid (ASF), may provide an appropriate condition for improving some sperm parameters in azoospermia. The objective was to investigate the impact of in vitro exposure of testicular and epididymal spermatozoa to ASF on sperm quality. The study was conducted on testicular (n = 20) and epididymal (n = 20) sperm specimens obtained from azoospermic men. Each sample was divided into two equal parts: Part I) for processing and incubation with Ham's F10 medium; Part II) for processing and incubation with ASF. RESULTS After 2 h incubation, testicular sperm motility was significantly higher in ASF than in Ham's F10 medium. In comparison to 0 h, mitochondrial membrane potential levels of testicular spermatozoa were significantly higher after 2 h and 24 h in ASF and after 24 h in Ham's F10 medium. Furthermore, the data indicated significantly lower rates of epididymal spermatozoa with high MMP in both media after 24 h. There were no significant differences in the DNA fragmentation index of testicular and epididymal spermatozoa between ASF and Ham's F10 medium at different time points. CONCLUSION The results demonstrated that in vitro incubation of testicular spermatozoa improved their motility more effectively than Ham's F10 medium in the short term (2 h), but had no effect on epididymal spermatozoa. Since the physiology of testicular spermatozoa is different from that of ejaculated spermatozoa, it seems that a special environment should be designed and used for each of them.

Prediction of microdissection testicular sperm extraction outcomes of azoospermic patients post-chemotherapy using cyclophosphamide equivalent dose. J Assist Reprod Genet 2023:10.1007/s10815-023-02870-4. [PMID: 37368159 PMCID: PMC10371929 DOI: 10.1007/s10815-023-02870-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2023] [Accepted: 06/20/2023] [Indexed: 06/28/2023] Open
Abstract
PURPOSE We determined the sperm retrieval rate in men with persistent azoospermia post-chemotherapy in relation to cyclophosphamide equivalent dose (CED), a unit for quantifying alkylating agent exposure. METHODS Medical records were retrospectively reviewed of 1098 patients diagnosed with non-obstructive azoospermia who had undergone microdissection testicular sperm extraction (mTESE) between January 2010 and 2021 at our institution. Twenty-three patients with a prior history of chemotherapy were included in the study. Oncological data, chemotherapy regime, and dosage were reviewed. The pretreatment hormone profile, CED, and mTESE outcomes were analyzed. RESULTS Testicular spermatozoa were successfully retrieved from 11 patients (47%). The mean patient age was 37.3 years (range, 27-41 years), and mean time interval from chemotherapy to mTESE, 11.8 years (range, 1-45 years). Patients exposed to alkylating agents had significantly lower sperm retrieval rates than those not exposed to alkylating agents (1/9, 11% vs. 10/14, 71%, p = 0.009). No men with CED > 4000 mg/m2 (n = 6) had viable sperm in the testes during mTESE. Moreover, patients diagnosed with testicular non-seminomatous germ cell tumors had a favorable sperm retrieval rate (67%) compared to patients with lymphoma (20%) or leukemia (33%). CONCLUSION Patients with permanent azoospermia post-chemotherapy have a lower testicular sperm retrieval rate when the chemotherapy regimen included alkylating agents. In cases where patients have undergone more intensive gonadotoxic treatments, such as higher CED, the likelihood of successful sperm retrieval is low. It is advisable to counsel such patients using the CED model prior to considering surgical sperm retrieval.

Abstract
Single sperm cryopreservation is a new method to preserve small numbers of spermatozoa in small droplets. So far, several devices have been introduced for this technique, but more studies are needed for its optimization. The aim of this study was optimizing the previous device for low number of spermatozoa and low volume semen, which led to design of Cryotop Vial device. Normal semen samples from 25 patients were prepared by swim-up method and divided into four groups: Fresh (F), Rapid freezing (R) and ultra-rapid freezing with Cryotop Device (CD) and Cryotop Vial Device (CVD). In R group, the diluted sperm suspension with sperm freezing medium was cooled in the vapor phase and then immersed in liquid nitrogen. Ultra rapid freezing was performed with sucrose in small volume using the Cryotop Device (CD) or Cryotop Vial Device (CVD). Sperm viability, motility, fine morphology, mitochondrial activity and DNA fragmentation were assessed in all samples. All sperm parameters decreased significantly in all the cryo groups compared to the fresh group. The comparison between the cryo groups showed that progressive motility (69.28 ± 6.82 vs. 55.68 ± 9.04, and 54.76 ± 5.34, p < 0.001) and viability (77.36 ± 5.48 vs.68.84 ± 8.51, p < 0.001, and 70.04 ± 7.44, P = 0.002) were significantly higher in the CVD compared to the CD and R groups respectively. DNA fragmentation was also significantly lower in both ultra-rapid freezing groups (CD and CVD) compared to the R group. Fine morphology and mitochondrial activity were not different between the cryo groups. The CVD as a cryoprotectant and centrifuge-free technique preserved sperm motility, viability and DNA integrity after cryopreservation better than other groups.

Abstract
Background and Aims Cryptozoospermia is an extreme oligozoospermia with an unsatisfactory treatment effect, with an incidence rate of approximately 8.73% in male infertility, whose effective solution has become the call of the times. Western Medicine has achieved certain effects through drugs, surgery, and assisted reproductive therapy, but this is still not ideal. Traditional Chinese medicine (TCM) has made many achievements in other disciplines; however, there is still a lack of evidence-based medical evidence to improve sperm production. Methods The relevant literatures from the China National Knowledge Internet (CNKI) and PubMed in the past 10 years were collected in this article, of which the mechanisms, advantages, or current controversies of various treatment methods of Western Medicine and TCM were analyzed, to find new treatment methods and research directions. Results With the development of modern science and technology, medical treatments for cryptozoospermia have become increasingly abundant; however, there is still no universally recognized unified and effective guiding plan. Although TCM has not been fully verified by evidence-based medicine, most TCM combined with Western Medicine can achieve unexpected results. Conclusion The combination of TCM and Western Medicine may become a bane for cryptozoospermia and bring good news to infertile men worldwide.

Microfluidic devices employing chemo- and thermotaxis for sperm selection can improve sperm parameters and function in patients with high DNA fragmentation. Andrologia 2022; 54:e14623. [PMID: 36379719 DOI: 10.1111/and.14623] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2022] [Revised: 09/12/2022] [Accepted: 09/28/2022] [Indexed: 11/17/2022] Open
Abstract
Conventional sperm processing uses centrifugation has a negative effect on sperm parameters and DNA integrity. We designed and fabricated a novel microfluid device based on chemotaxis and thermotaxis, and compared it with the swim-up method. Twenty normal samples with high DNA fragmentation were included. Each sample was divided into four groups: Group 1, control, Group 2: sperm selection by thermotaxis, Group 3: sperm selection by chemotaxis, and Group 4: sperm selection with thermotaxis and chemotaxis. We used cumulus cells in a microfluid device to create chemotaxis, and, two warm stages to form a temperature gradient for thermotaxis. The spermatozoa were assessed based on the concentration, motility, and fine morphology using Motile Sperm Organelle Morphology Examination, mitochondrial membrane potential (MMP), acrosome reaction (AR), and sperm DNA fragmentation. Concentration (22.40 ± 5.39 vs. 66.50 ± 19.21; p < 0.001) and DNA fragmentation (12.30 ± 3.96% vs. 17.95 ± 2.89%; p < 0.001) after selection in the chemotaxis and thermotaxis microfluid device were significantly lower than control group. The progressive motility (93.75 ± 4.39% vs. 75.55 ± 5.86%, p < 0.001), normal morphology (15.45 ± 2.50% vs. 10.35 ± 3.36, p < 0.001), MMP (97.65 ± 1.81% vs. 94 ± 3.89%, p = 0.02), and AR status (79.20 ± 5.28% vs. 31.20 ± 5.24%, p < 0.001) in the chemotaxis and thermotaxis microfluid device were significantly increased compared to control group. According to these findings, spermatozoa that have penetrated the cumulus oophorus have better morphology and motility, as well as acrosome reactivity and DNA integrity.
