ABSTRACT

PURPOSE OF REVIEW: To review noteworthy research from the last 2 years on surgical management of azoospermia. RECENT FINDINGS: The recommended treatments for nonobstructive and obstructive azoospermia have not appreciably changed. However, recent level-1 evidence has reinforced superiority of micro-dissection testicular sperm extraction over sperm aspiration in men with nonobstructive azoospermia, and several studies have identified genetic and other clinical factors that may aid in selecting candidates for testicular sperm extraction. Machine learning technology has shown promise as a decision support system for patient selection prior to sperm retrieval as well a tool to aid in sperm identification from testis tissue. SUMMARY: Most men with obstructive azoospermia who desire fertility can be offered either surgical reconstruction or sperm retrieval. For men with nonobstructive azoospermia, sperm retrieval with microdissection testicular sperm extraction remains the gold standard treatment. Uncovering more genetic causes of nonobstructive azoospermia may aid in properly counseling and selecting patients for microdissection testicular sperm extraction. Neural networks and deep learning may have a future role in patient selection for surgical sperm retrieval and postprocedural sperm identification.

ABSTRACT

A total of 130 patients who underwent percutaneous testicular sperm aspiration from March 2021 to February 2023 were randomly divided into a Dezocine group and a control group. The Dezocine group received a muscle injection of 0.05mg/kg Dezocine 30 minutes before surgery, while the control group received a muscle injection of 0.01ml/kg normal saline. Both groups received 3ml of 2% lidocaine for spermatic cord block anesthesia. The anesthesia onset time, anesthesia duration, numeric rating scale (NRS) score, anesthesia satisfaction rate and incidence of adverse reactions were recorded and compared between the two groups. The statistical results showed that there were significant differences between the two groups in terms of anesthesia onset time, anesthesia duration, anesthesia satisfaction rate, non-steroidal anti-inflammatory drug (NSAID) use within 24 hours after surgery and NRS scores at 15 minutes, 1 hour and 2 hours after surgery. The incidence of adverse reactions in the Dezocine group was lower than that in the control group, but the difference was not statistically significant. The combination of Dezocine and lidocaine for spermatic cord block anesthesia during percutaneous testicular sperm aspiration is safe, effective and associated with fewer adverse reactions. It is suitable for clinical application and promotion in reproductive medicine outpatient surgery.

ABSTRACT

The aim was to investigate the influences of different sperm sources on clinical outcome and neonatal outcome of patients with intracytoplasmic sperm injection. We retrospectively analysed patients who underwent intracytoplasmic sperm injection in our reproductive centre from 2011 to 2020. We screened data on assisted reproductive outcomes from four groups of sources: testicular sperm, epididymal sperm, ejaculated sperm and donor sperm for analysis and divided the non-ejaculated group from the ejaculated group to explore their impact on clinical outcomes and neonatal outcomes. A total of 2139 cycles were involved in this study. There were significant differences in fertilisation rate (77.0% vs. 73.6%, p < .001), cleavage rate (97.4% vs. 94.4%, p < .001) and high-quality embryo rate (52.8% vs. 49.9%, p < .001) between the ejaculated and non-ejaculated sperm groups. There were no significant differences amongst the four groups in biochemical pregnancy rate, clinical pregnancy rate, abortion rate, live birth rate, male-female ratio and single-twin ratio. Different sperm sources did not affect the length, weight or physical defects of newborns amongst the groups. Sperm source did not affect pregnancy and neonatal outcomes of intracytoplasmic sperm injection in general.

ABSTRACT

AIMS: To evaluate the results of microdissection testicular sperm extraction (micro-TESE) and intracytoplasmic sperm injection (ICSI) for treatment of non-obstructive azoospermia (NOA). MATERIALS AND METHODS: We retrospectively analysed data of 88 consecutive patients with clinical NOA who were treated with micro-TESE by a single surgeon, between August 2014 and September 2020, in Melbourne, Victoria. Upon a successful sperm retrieval, sperm was either used fresh for ICSI, frozen for future use or both. The outcome measures were sperm retrieval rate (SRR), and in vitro fertilisation (IVF)/ICSI results. Furthermore, SRR was calculated for the predominant causes and histopathological patterns. RESULTS: The overall SRR was 61.2%. It was significantly higher in patients with a history of cryptorchidism and other childhood diseases (100%) than in the other NOA groups (P < 0.05). Patients with Klinefelter syndrome had a 75% SRR. Among the different types of testicular histology, the highest SRR were noted in patients with complete hyalinisation (100%) and hypospermatogenesis (92.9%), and low with Sertoli cell-only syndrome (46.3%). The SRR has significantly increased from 33.3% in 2015-2016 to 73.6% in 2019-2020 (P = 0.009). Of the 52 patients with SSR, 47 underwent IVF/ICSI. Fertilisation rate was 42.4%. Twenty-nine couples achieved at least one good-quality embryo and had embryo transfer. Nineteen achieved pregnancy (40.4%), and in three patients a miscarriage resulted. CONCLUSIONS: This is the first report from Australia showing that micro-TESE is an effective treatment for NOA with high SRR. The increasing success rates over several years indicate the importance of surgical skill and laboratory staff experience.

ABSTRACT

RESEARCH QUESTION: What are the cumulative clinical pregnancy rates (CPR) and live births rates (LBR) in intracytoplasmic sperm injection (ICSI) cycles using testicular motile compared with immotile spermatozoa, obtained from testicular sperm aspiration (TESA) or extraction (TESE)? DESIGN: A retrospective analysis of ICSI cycles using TESA or TESE over a period of 7 years. Cycles were divided into two groups according to the motility of the retrieved spermatozoa: Group A consisted of couples with motile spermatozoa; Group B of couples with immotile spermatozoa. Group B was subdivided into two groups: B1 consisted of couples with motile spermatozoa and B2 with immotile spermatozoa after the addition of pentoxifylline. RESULTS: No differences in CPR and LBR per transfer was found between the study groups after fresh embryo transfer. No pregnancies were achieved by vitrified-warmed embryo transfer in group B2. Fertilization rates decreased when using immotile spermatozoa (64.4%, 56%, 37.9%, for groups A, B1 and B2, respectively, P < 0.001). Top-quality embryo rates were higher in groups A and B1 compared with B2 (40.7% and 40.1% versus 19.1%, respectively, P = 0.015). Cumulative CPR (53%, 41.7%, 13.6% for groups A, B1 and B2, respectively, P = 0.005) and LBR (42.4%, 30%, 13.6% for groups A, B1 and B2, respectively P = 0.03) per oocyte retrieval was significantly higher when using motile spermatozoa compared with motile or immotile spermatozoa after adding pentoxifylline. CONCLUSIONS: Although fertilization, top-quality embryo rates, cumulative CPR and LBR decreased when using immotile spermatozoa, ICSI is still valid; therefore, it should be considered and offered to couples before embarking on a donor sperm insemination cycle, or cryopreserving oocytes for future additional testicular sperm retrieval.

ABSTRACT

Recently a novel method based on horizontal sperm migration in injection dishes has been introduced as an additional tool for preparation of semen sample in assisted reproductive technology (ART) procedures. In the present study, we evaluated both timing and reproductive outcomes in a randomized controlled study including 1034 intra-cytoplasmic sperm injection (ICSI) procedures followed by fresh embryo transfer. Couples enrolled were divided into two sub-groups, namely conventional swim-up method (Group A), and horizontal sperm migration in injection dishes (Group B).No significant differences were found between groups with respect to fertilization rate, implantation success, clinical pregnancy outcomes and ongoing pregnancies. On the contrary, both cleavage and blastocyst rates were statistically higher in Group B, suggesting superior efficiency and safety of this innovative technique also including time-saving and cheaper costs as compared to the classical swim-up sperm preparation.Our data support the interpretation of the horizontal sperm migration as a promising procedure for semen preparation in ART cycles.

ABSTRACT

BACKGROUND: Scrotal hemorrhage after testicular sperm aspiration (TESA) is uncommon in clinical operation. Phosphodiesterase-5 inhibitors (PDE5i) are commonly given to men who have difficulty providing a sperm sample for assisted reproductive technique such as in vitro fertilization. In this study, we examine the incidence of scrotal hemorrhage after TESA in men who received a PDE5i. METHODS: In this retrospective study, 504 men with TESA operation in Center for Reproductive Medicine, Nanfang Hospital, Southern Medical University were collected. Men in the drug group had taken orally PDE5i before TESA. Men in the control group only operated TESA. The testis volume, coagulation function were measured. Sonographic examination with Doppler imaging was performed when scrotal hemorrhage appeared. RESULTS: A total of 504 men with a mean age of 28.63 ± 4.22 years were included in the analysis. Of these, 428 did not receive a PDE5i prior to TESA and 76 received a PDE5i prior to TESA. Measures of coagulation function were not different between the groups. The incidence of hemorrhage was 0.0% in the control group and the drug group was 5.3%. The incidence of hemorrhage between two groups was different significantly (P = 0.000). CONCLUSION: In summary, the results of this study suggest that a PDE5i administration increases the risk of scrotal hemorrhage in men undergoing TESA, although the study design does not allow drawing a conclusion of cause and effect. Given the potential risk of scrotal hemorrhage after the ingestion of PDE5i, it may be wise not to administer it to men in whom a TESA may be performed.

ABSTRACT

Sperm DNA damage, excessive oxidative stress and decrease in motility may lead to low fertilisation or poor assisted reproductive techniques outcomes in asthenoteratozoospermic men. Selenium was considered as essential element for male reproductive functions. Selenium has important role in enzymatic process for elimination of excessive reactive oxygen species and helps to maintain membrane integrity. The aim of this study was to determine the effect of selenium supplementation on sperm quality, DNA fragmentation, mitochondrial membrane potential and membrane lipid peroxidation during sperm sampling in vitro at different times. In this experimental study, semen samples were collected from 50 asthenoteratozoospermic men. Samples were divided into two groups as control group and test group (incubated with 2 µg/ml selenium at 37°C for 2, 4 and 6 hr). Motility and viability were assessed based on WHO 2010 criteria. Mitochondrial membrane potential, sperm DNA fragmentation and malondialdehyde levels were evaluated in each group. Results revealed that motility, viability and mitochondrial membrane potential were significantly higher in the test group (p < .05). Also malondialdehyde levels were significantly lower in the test group (p < .03). DNA fragmentation significantly decreased in the test group after 6 hr of incubation (p < .02). In conclusion, in vitro selenium supplementation may protect spermatozoa from maltreatment effect of reactive oxygen species (ROS) during sperm sampling via keeping enzymatic and antioxidant process in optimum condition.

ABSTRACT

PURPOSE: To assess the impact of sperm retrieval on the gonadal function of rats with impaired spermatogenesis by comparing testicular sperm extraction (TESE) to aspiration (TESA). The efficacy of these procedures to sperm obtainment was also compared. MATERIALS AND METHODS: A pilot study showed impaired spermatogenesis, but normal testosterone (T) production after a bilateral orchidopexy applied to 26 rats, which were randomly assigned into four groups: TESE (n=7), TESA (n=7), SHAM (n=6) and Control (n=6). The T levels were measured through comparative analysis after the orchidopexy. RESULTS: There was no statistical difference in the animal's baseline T levels after orchidopexy in comparison to the controls: the TESE and TESA groups, 6.66±4.67ng/mL; the SHAM group (orchidopexy only), 4.99±1.96ng/mL; and the Control, 4.75±1.45ng/ mL, p=0.27. Accordingly, no difference was found in the postoperative T levels: TESE, 5.35±4.65ng/mL; TESA, 3.96±0.80ng/mL; SHAM, 3.70±1.27ng/mL; p=0.4. The number of sperm cells found through TESE (41.0±7.0) was significantly larger than that found through TESA (21.3±8.1, p=0.001). Moreover, higher tissue weight was found through TESE (0.09±0.02g versus 0.04±0.04g, p=0.04). CONCLUSIONS: The testicular sperm capture performed in rats through extraction or aspiration, after orchidopexy, did not significantly decrease the T levels. The amount of sperm found through testicular sperm extraction was higher than that through testicular sperm aspiration.

ABSTRACT

STUDY DESIGN: Prospective, three-way crossover design. OBJECTIVE: Penile vibratory stimulation (PVS) is recommended as the first line of treatment for semen retrieval in anejaculatory men with spinal cord injury (SCI). This study compared ejaculatory success rates and patient preference for three methods of PVS within the same group of men with SCI. SETTING: Major medical university. METHODS: Fifteen men with SCI each received three methods of PVS. Method 1 (M1): applying one FertiCare Personal device to the dorsum or frenulum of the glans penis; Method 2 (M2): 'sandwiching' the glans penis between two FertiCare devices; Method 3 (M3): sandwiching the glans penis between the two vibrating surfaces of the Viberect-X3 device. The order of M1, M2 and M3 was varied to control for sequencing effects. Following each PVS trial, subjects rated their experience on a questionnaire with scaled responses. RESULTS: Ejaculation success rates were high for each method; however, ejaculation latency was significantly longer with M3 compared with M1 or M2. In survey questions about patient preference, there were no significant differences between M1 and M2. In contrast, M3 was rated lower than M1 and M2 in patient preference. Semen collection may be more difficult with the Viberect device. CONCLUSIONS: On the basis of these findings, we recommend attempting PVS with one FertiCare device. If that fails, use two FertiCare devices. Although the Viberect-X3 was preferred less by patients, it had similar efficacy as the Ferticare vibrator(s) and may be suitable for home use by some patients.

ABSTRACT

The development of testicular sperm extraction (TESE) and intracytoplasmic sperm injection (ICSI) has made it possible for patients with non-obstructive azoospermia to have their own children. However, sperm retrieval by conventional TESE succeeds but in a subset of patients and, therefore, how to improve the success rate of sperm retrieval is becoming a focus of research. Recent studies suggest that microdissection TESE, although with its limitations, has obvious advantages over traditional sperm retrieval methods. This article presents an overview on the characteristics, predictive factors, sperm retrieval rate, post-operative complications, and improvement of microdissection TESE.

ABSTRACT

INTRODUCTION: In obstructive azoospermia, choosing a sperm retrieval method for intracytoplasmic sperm injection (ICSI) depends on the preference and expertise of both the urologist and the reproductive endocrinologist. Generally, a percutaneous epididymal sperm aspiration (PESA) is attempted first. Not uncommonly, multiple PESA's are necessary. This study utilizes a rat model to provide an understanding of sperm parameter and histological changes resulting from repetitive PESA procedures. MATERIALS AND METHODS: A cohort of 30 male Wistar rats of reproductive age (68-73 days) was divided into three groups of 10 (G1-G3). All three groups underwent a left epididymal head PESA using a 253/8 gauge needle. The untouched right epididymis acted as the control. At 14 day intervals, G2 and G3 underwent a second and third PESA respectively. Fourteen days after the final PESA, both epididymides and a 1 cm segment of both vas deferentia were harvested for sperm and histological evaluations. RESULTS: The percentage of vas specimens with a sperm count ≥ 5 x104/cc was 100%, 22%, and 20% for the G1, G2, G3 PESA samples respectively. Moreover, the percentage of the vas specimens with sperm motility ≥ 10% was 90%, 22%, and 20%, respectively. Epididymal granulomas were not seen in the control side, but formed in 70%, 100%, and 80% of G1, G2, G3 PESA specimens, respectively. CONCLUSIONS: In a rat model, PESA resulted in significant epididymal inflammation and a reduction in both sperm concentration and motility.

ABSTRACT

PURPOSE: We evaluated the effect of daily perioperative celecoxib on patient reported pain control and opioid use after testicular surgery. MATERIALS AND METHODS: Men scheduled to undergo elective outpatient microsurgical testicular sperm extraction were prospectively randomized to receive 200 mg celecoxib or placebo twice daily, which was initiated the night before surgery and continued for 6 days thereafter. Using an 11-point visual analog scale, participants self-reported the postoperative pain level and acetaminophen/hydrocodone use for supplemental pain control. We compared differences in pain scores and opioid use between the 2 patient groups using the Student t test with p<0.05 considered significant. RESULTS: At 1-year interim analysis 35 of 78 eligible participants (45%) had returned the study questionnaire, of whom 34 were included in the final analysis. Of the 34 patients the 16 who received celecoxib had significantly lower postoperative opioid use than those on placebo (6 vs 16 pills, p=0.02). We noted a statistically significant difference in postoperative day 1 and 2 patient reported pain scores (4 vs 6, p<0.05 and 3 vs 5, p=0.03) and opioid use (1 vs 5 pills, p<0.01 and 2 vs 4, p=0.02) seen between the celecoxib and placebo groups, respectively. No study complications were identified. The trial was terminated early based on the results of interim analysis. CONCLUSIONS: Twice daily celecoxib use started preoperatively significantly decreased patient reported postoperative pain and opioid use, especially in the early postoperative period. A short course of celecoxib is well tolerated and may be effective as part of multimodal postoperative analgesia in patients who undergo testicular surgery for sperm retrieval.

ABSTRACT

STUDY QUESTION: Does neonatal outcome including congenital malformations in children born after ICSI with epididymal and testicular sperm [testicular sperm extraction (TESE)/percutaneous epididymal sperm aspiration (PESA)/testicular sperm aspiration (TESA) (TPT)] differ from neonatal outcome in children born after ICSI with ejaculated sperm, IVF and natural conception (NC)? SUMMARY ANSWER: Children born after TPT have similar neonatal outcome, including total malformation rates, as have children born after ICSI and IVF with ejaculated sperm. Testing for variance over the four groups may indicate smaller differences in specific malformation rates with TPT as the highest risk group. WHAT IS KNOWN ALREADY: Regarding neonatal outcome as well as congenital malformations in children born after TPT, studies are few, with limited sample size, heterogeneous and often performed without relevant control groups. STUDY DESIGN, SIZE, DURATION: Population-based cohort study including all Danish children born after TPT and fresh embryo transfer in Denmark from 1995 to 2009. Children born after transfer of frozen-thawed embryos were excluded. Control groups of children conceived by ICSI with ejaculated sperm, IVF and NC were identified by cross-linkage of the Danish IVF Register, Medical Birth Register (MBR) and National Hospital Discharge Register (HDR). PARTICIPANTS/MATERIALS, SETTING: The study group consisted of 466 children born after TPT, while the control groups consisted of 8967 (ICSI with ejaculated sperm), 17 592 (IVF) and 63 854 (NC) children. Neonatal outcomes and congenital malformations were analysed for singletons and twins separately. Risk estimates for low birthweight (LBW, <2500 g) and preterm birth (PTB, <37 gestational weeks) were adjusted for maternal age, parity, child gender and year of childbirth. The study group was identified from the Danish national database on children born after TPT. Control groups were obtained from the IVF register and the MBR. All information included in the study was retrieved from the national registers. MAIN RESULTS AND THE ROLE OF CHANCE: Considering singletons and twins as one group, the sex ratio (♂/♀) was significantly lower for children born after TPT (0.89) compared with conventional IVF (1.11; P = 0.017) but did not differ significantly when compared with ICSI with ejaculated sperm (0.94) and NC (1.05). The mean birthweight (BW) for singletons did not differ significantly between groups when including only first-born children. The mean gestational age (GA) in the TPT singletons (279 ± 12 days) was significantly higher compared with IVF (276 ± 18 days; P = 0.02), but similar to ICSI with ejaculated sperm and NC singletons when including only first-born children (277 ± 16 days and 279 ± 14 days, respectively). Rate of stillbirths, perinatal and neonatal mortality in the group of TPT singletons did not differ significantly from any of the control groups. Comparable results were found for the TPT twin group, except for perinatal mortality, which was significantly lower in the TPT group compared with naturally conceived twins. The adjusted risk of LBW was significantly higher for TPT versus NC singletons [adjusted odds ratio (AOR) = 0.67 (0.48-0.93)]; however AOR for PTB was similar in the two groups. Regarding twins, similar adjusted risks were observed for PTB and LBW between the TPT and all three control groups. Significantly more Caesarean sections were performed after IVF (27.3% for singletons) and ICSI (25.1% for singletons) with ejaculated sperm compared with the TPT group (16.4% for singletons). The total rate of congenital malformations in the TPT group was 7.7% and did not differ significantly from any of the control groups. However, singleton TPT boys showed an increased rate of cardiac malformations (3.6%) compared with singleton boys after IVF (1.4%; P = 0.04) and NC (1.1%; P = 0.02). Considering the level of male infertility as a continuum over the four groups, tests for variance in the rate of cardiac malformations in singleton boys, and undescended testicles for singleton as well as twin boys were each significantly increased from NC to IVF to ICSI to TPT (P < 0.001). The rate of hypospadias showed the same pattern, but the TPT group did not differ significantly compared with the control groups. LIMITATIONS, REASONS FOR CAUTION: One of the limitations is that the TPT group could not be classified according to testicular or epididymal sperm, as these data were not available in the IVF register. Another limitation is that registry-based studies are encumbered with the risk of reporting or coding errors or missing data due to insufficient coding. However, the quality of data on congenital malformations in HDR has, in other studies, been validated and found acceptable for epidemiological research, and furthermore, recordings on study and control groups are performed similarly. WIDER IMPLICATIONS OF THE FINDINGS: Accumulating data show that TPT treatment is equally safe as conventional ICSI and IVF treatment and as NC with regard to neonatal outcome including congenital malformation. STUDY FUNDING/POTENTIAL COMPETING INTERESTS: This study is supported by Laboratory of Reproductive Biology, Scientific Unit, Horsens Hospital. No competing interests declared.

ABSTRACT

Artificial insemination (AI) can help to avoid inbreeding and genetic degeneration for sustaining genetically healthy populations of endangered species in captivity. Collection of a sufficient quantity of viable sperm is an essential first step in the AI process. In the present study, we examined the effects of frequent electroejaculation on semen characteristics in a Siberian tiger. We collected semen in all 17 trials during 6 breeding seasons (6 years). The mean number of sperm and the percentage of motile sperm were 294.3 ± 250.2 × 106/ejaculate and 82.4 ± 11.4%, respectively. The number of motile sperm tended to increase during frequent electroejaculation in the same breeding season. Semen collection by electroejaculation can be performed effectively up to the fourth sequential ejaculate, which contained the most sperm in the study. In conclusion, frequent collection of sperm by electroejaculation from tigers may be effective for collection of a large number of motile sperm.

ABSTRACT

PURPOSE: To explore the prevalence and risk factors for depression in men undergoing different assisted reproductive technique (ART) treatments in Chinese population. METHOD: This was a prospective study of 844 men undergoing ART treatments. All men were distributed to four groups, according to they received treatments. The treatments included IUI (intrauterine insemination), IVF(in vitro fertilization), ICSI(intra cytoplasmatic sperm injection) and TESA/PESA (percutaneous epididymal sperm aspiration/testicular sperm aspiration). Their symptoms of depression were measured with use of the Center for Epidemiologic Studies of Depression scale(CES-D). Data were collected about age, BMI, education, duration of marriage, duration of infertility, smoking, type of infertility, infertility causes, history of ejaculation failure, and financial burden of the treatment. We estimated the prevalence of depressive symptom in men undergoing different ART and used logistic regression models to identify risk factors for depression in different groups. RESULTS: The overall prevalence of depression was 13.3 % for men undergoing ART treatments: 14.5 % of IUI group, 12.4 % of IVF group, 19.2 % of ICSI group and 6.2 % of TESA/PESA group. Prevalence of depression among IUI group, IVF group and ICSI group were not significantly different. For IUI group, the factors were found to increase depression risk were treatment financial burden and duration of marriage, to decrease depression risk was age. For IVF group, the risk factors independently associated with depression were both male and female infertility, unexplained infertility, and history of ejaculation failure. CONCLUSION: In a sample of Chinese men undergoing ART treatments, the prevalence of depression was higher than other country. The risk factors for depression varied in different ART treatments groups. when routine screening to identify the sub-group of vulnerable men which need counselling before ART treatments, we should also consider which pattern of ART treatments the man underwent.

ABSTRACT

In men with non-obstructive azoospermia (NOA), the risk of hypogonadism is often overlooked. Testicular sperm extraction (TESE) may increase this risk. The objective of this study was to elucidate the prevalence of hypogonadism in NOA-patients, the impact of TESE on hormone balance and the association between testosterone deficiency and dyslipidaemia. Men with NOA who had undergone TESE during the period 2004-2009 were eligible. Hypogonadism was defined as total testosterone <10 nmol/L and/or LH >10 IU/L and/or ongoing androgen replacement therapy. Sixty-five consecutive men who had undergone TESE owing to NOA and from whom post-TESE serum testosterone levels measured before 1100 h were available. Furthermore, 141 fertile men served as controls. Serum concentrations of testosterone, LH and lipids were assessed. Odds ratios (OR) for biochemical hypogonadism were calculated. Pre- and post-TESE hormone levels were compared. Lipid profile was related to testosterone levels. Hypogonadism was found in 47% (95% CI, 0.36, 0.59) of the NOA-men. As compared with fertile controls, the OR for hypogonadism post-TESE was 17 (95% CI 6.6-45). Serum LH (p = 0.03), but not testosterone (p = 0.43), differed significantly pre- and post-TESE. Compared with eugonadal NOA-men, the OR for having deviations in lipid profile was 3.3 (95% CI 1.3-8.8) for the hypogonadal NOA-men. NOA-men are at very high risk of androgen deficiency, which even in young subjects is associated with dyslipidaemia. Medical management of these men should therefore include endocrinological evaluation and follow-up after completion of infertility treatment.

ABSTRACT

PURPOSE: Testicular spermatozoa can be retrieved successfully by the testicular sperm extraction (TESE) procedure and used for intracytoplasmic sperm injection. Disruption in the blood-testis barrier can lead to the production of antisperm antibodies (ASA). The aim of this prospective study was to investigate the frequency of ASA formation in couples after TESE procedure. METHODS: Thirty-seven couples were included in the study at the Urology Clinic of the Dr. Zekai Tahir Burak Women's Health Training and Research Hospital. History, physical examination, spermiogram, and endocrine profiles were obtained for all male patients. All the male patients in this study had been diagnosed with nonobstructive azoospermia (NOA) and underwent microdissection TESE. Secondary and tertiary cases were also included in the study. Serum samples were obtained from all 74 patients before TESE, and at three and 12 months after TESE. Serum ASA levels were determined. ANOVA was performed for statistical analysis for serum Follicle-Stimulating Hormone (FSH), testosterone and testicular volume. P < 0.05 was considered significant. RESULTS: There were no differences in the testicular volumes, serum FSH and testosterone levels before and after TESE. None of the patients or their partners developed significant levels of ASA as a result of the TESE procedure. CONCLUSION: TESE procedure does not cause ASA production in either males or their female partners.

ABSTRACT

OBJECTIVE: Microbial contamination of ART culture media is rare but serious. We examined our own experience and conducted a review of the literature with a view to preventing its occurrence and recurrence. CASE REPORT: A total of 12 cases were recorded during January 2006 to March 2019. The contaminations were caused by semen and were shown to be bacteria that were resistant to the prophylactic antibiotics used in the medium. After the procedures were cancelled due to contaminations, nine husbands received antibiotic treatment, while nine couples changed over to the ICSI program. Eventually, eight couples concluded the study with live birth deliveries, and there was no recurrence of contamination. CONCLUSION: ART laboratories should preserve all sperm suspension samples until embryo transfer has been completed for the purpose of checking whether contamination has occurred. In addition to antibiotic treatment, implementation of the ICSI procedure during the next ART cycle has already been proven to be effective. In the future, the zona-removal technique may be considered as another potential option.

ABSTRACT

BACKGROUND: Suboptimal human semen handling in vitro may induce sperm damage. However, the effects of semen swim-up, pellet swim-up, density gradient, and density gradient followed by SU on sperm motility, morphology, DNA fragmentation, acrosome reaction, intracellular reactive oxygen species, and mitochondrial activity were not fully understood. OBJECTIVES: To study the impact of four sperm preparation techniques on sperm functional parameters. MATERIALS AND METHODS: This study was conducted on 60 infertile men with a minimum sperm concentration of 20 × 106 /ml and total sperm motility of ≥30%. Each raw semen sample was divided into four aliquots. Each aliquot was prepared by one of the tested techniques. Various sperm characteristics were assessed before and after sperm preparation. RESULTS: Density gradient and density gradient followed by SU resulted in significantly higher DNA fragmentation percentages compared with semen swim-up (p < 0.001 and p < 0.001, respectively) and pellet swim-up (p < 0.001 and p < 0.001, respectively). Significantly higher percentages of spermatozoa with intact acrosome were detected in semen swim-up (p < 0.001) and pellet swim-up (p < 0.001) compared with raw semen. The percentage of reactive oxygen species-positive spermatozoa was significantly higher after pellet swim-up (p < 0.001), density gradient (p < 0.001), and density gradient followed by SU (p < 0.001) than raw semen. In addition, the percentages of 100% stained midpiece (active mitochondria) were significantly higher in semen swim-up (p < 0.001) and pellet swim-up (p < 0.001) compared with raw semen. DISCUSSION AND CONCLUSION: To the best of our knowledge, this is the first report comparing the impact of these techniques on various sperm functional parameters. Semen swim-up was more effective than density gradient in selecting better spermatozoa in terms of DNA integrity, reactive oxygen species levels, acrosome status, and mitochondrial activity. Randomized clinical trials comparing these four techniques are required to test their impact on embryo development and pregnancy outcomes.
