Therapeutic challenges in metastatic follicular thyroid cancer occurring in pregnancy: A case report

BACKGROUND

Hormones could play a role in the evolution of follicular thyroid cancer (FTC) for which we discuss an unusual presentation of FTC occurring during pregnancy.

CASE SUMMARY

A pregnant woman was admitted with FTC metastasis resulting in a gluteal mass. Preoperative abdominal computed tomography revealed liver metastasis for which the patient underwent total thyroidectomy and liver resection, oral radioiodine therapy and radiotherapy, followed by embolization of the pelvic mass. The patient died of cerebral hemorrhage 16 mo after the initial diagnosis.

CONCLUSION

Human chorionic gonadotropin and estrogen stimulation might have a role in cancer growth, especially during pregnancy. FTC management aims to stop disease progression and overcome hormonal imbalances after thyroidectomy thus reducing fetal complications. It is still under debate whether it is possible to combine optimal timing for treatment to ensure the best possible outcome with reduction of fetal complications and risk of cancer growth.

Sperm retrieval by conventional testicular sperm extraction for assisted reproduction in patients with Zinner syndrome

We present data from three Caucasian men with Zinner syndrome who attended our center for the treatment of primary couple’s infertility. Each patient was scheduled for conventional testicular sperm extraction (cTESE) and cryopreservation. Sperm analysis confirmed absolute azoospermia. Patient 1 had right and left testis volumes of 24 mL and 23 mL, respectively; left seminal vesicle (SV) agenesis, severe right SV hypotrophy with right renal agenesis. Follicle-stimulating hormone (FSH) was 3.2 IU/L. Patient 2 exhibited right and left testis volumes of 18 mL and 16 mL, respectively; a left SV cyst of 32 × 28 mm, ipsilateral kidney absence, and right SV agenesis. FSH was 2.8 IU/L. Patient 3 showed a testicular volume of 10 mL bilaterally, a 65 × 46 mm left SV cyst, right SV enlargement, and left kidney agenesis. FSH was 32.0 IU/L. Sperm retrieval was successful in all patients. Nevertheless, cTESE should be performed on the day of oocyte retrieval.

The Impact of the COVID-19 Quarantine on Sexual Life in Italy

OBJECTIVE

The aim of the study is to evaluate how individual and couple's sexuality had changed during the COVID-19 pandemic-related quarantine.

METHODS

A quantitative correlational research study was conducted, using a web-based survey.

RESULTS

About 1576 participants were involved: 1018 women (64.6%) and 558 men (35.4%). A significant decline in the mean well-being scores during the quarantine, compared to before, was reported. A positive correlation between the well-being scores and the number of sexual intercourse (SI) before and during the quarantine was found. The mean number of SI decreased significantly during the quarantine. The main reasons were: poor privacy (43.2%) and lack of psychological stimuli (40.9%). About 1124 respondents (71.3%) did not report sexual desire (SD) reduction. A positive association between SD and SI during the quarantine was found. About 61.2% did not report autoerotism reduction. In those who reported decreased masturbation activity, the main causes were poor privacy (46.4%) and lack of desire (34.7%). We found that men presented lower SD during the quarantine, than women (P < 0.01).

CONCLUSION

Potentially, the more time available might lead couples to reconnect at an intimate level and to improve their sexuality. However, the majority of quarantined participants experienced reduced number of SI per week, with poor household privacy and lack of psychological stimuli as cited causes, even as a majority did not report reduced autoeroticism.

Cardiometabolic and Thrombotic Risk Profile in Women Undergoing Oocyte Donation for Assisted Reproduction

Background: The last two decades have seen a growing number of pregnancies in women who needed the donation of oocytes. With oocyte donation pregnancies, studies on obstetric outcomes among these women revealed an increased incidence of pre-eclampsia and pregnancy-induced hypertension. Furthermore, several studies have found a higher incidence of low birth weight, preterm birth, and delivery by cesarean section in oocyte donation rather than in women subjected to assisted reproduction techniques (ART) with autologous oocytes. Numerous studies have also shown a deep connection between cardiovascular and thrombotic risk factors and adverse pregnancy outcomes. In this setting, to strictly assess the preconceptional risk for women who undergo egg donation to achieve pregnancy, the aim of our study is to draw a detailed assessment of the vascular risk profile of patients with gamete donation ART indications through the evaluation of comorbidities and cardiometabolic and thrombophilic markers Materials and Methods: Patients undergoing ART with oocyte or sperm donation or double donation of gametes underwent a careful clinical assessment through a detailed personal and family anamnesis and they were evaluated for cardiometabolic and thrombophilic profile. Clinical and demographic characteristics, comorbidities, and biohumoral parameters were collected. The study was approved by the Regional Ethical Committee(Em 2018-017 CINECA 10189). Results: We evaluated 525 women. Around 73.1% were >40 years and 35% of them were older than 45 years. There was a high prevalence of dyslipidemias (58.1%), smoking habit (24.6%), a body mass index >25 in 28.6% of patients, a high abdominal circumference in 58.1% of cases, a prevalence of acquired thrombophilia in about 7% and hereditary of 19.2%. Around 39.2% of patients had total cholesterol >200 mg/dL, 19.5% had high-density lipoprotein <48 mg/dL and 43.6% had low-density lipoprotein >115 mg/dL, and 6.9% had triglyceride values >150 mg/dL. Conclusions: A careful assessment of the preconceptional status of patients undergoing ART programs with oocyte donation can be highly recommended.

'Two countries-two labs': the transnational gamete donation (TGD) programme to support egg donation

PURPOSE

To evaluate the effectiveness, efficiency, and safety of a transnational gamete donation (TGD) programme based on the shipping of vitrified donor oocytes.

METHODS

A retro-prospective observational study was conducted in the Assisted Reproductive Technology Center of the University Hospital of Florence, Italy. The study population included 622 consecutive donor oocyte cycles. A mean number of 6 vitrified oocytes per couple were shipped from two Spanish biobanks. In the receiving centre, gametes were warmed and inseminated and the subsequent embryo transfer (ET) was performed. The main outcome measurement was LBR. Secondary outcomes included oocyte survival rate, ICSI damage rate, normal fertilization, cleavage, and implantation rate (IR) in both 'fresh' and cryotransfer cycles.

RESULTS

A total number of 3536 mature oocytes were warmed with 81.4% surviving oocytes. 2PN oocytes were 1941 with an ICSI normal fertilization rate of 70.4% and a cleavage rate of 93.4%; 857 day-3 embryos were transferred in 498 women, 63 blastocysts in 44. Couples with at least one vitrified embryo were 181 (32.3%). IR was 25.1% and 33.1% for day-3 ET and blastocyst stage respectively. Crude pregnancy rate and LBR after the first ET were 35.5% and 27% correspondingly with a conservative cumulative LBR of 34% and an optimal LBR of 51.4%.

CONCLUSION

Imported vitrified donor oocytes retain their competence and are capable of resulting in ongoing pregnancies and healthy babies in a proportion comparable to other existing systems as egg donation with vitrification/warming in the same laboratory and transnational fresh oocyte donation.

Clinical Use of Indocyanine Green in Bowel Endometriosis Surgery

STUDY OBJECTIVE

To show feasibility of using indocyanine green (ICG) in endometriosis surgery, especially bowel endometriosis shaving, and to discuss its potential benefits.

DESIGN

Stepwise demonstration of this technique with narrated video footage.

SETTING

Endometriosis is a common benign chronic disorder, characterized by the presence of endometrial tissue outside the uterus. Deep infiltrating endometriosis (DIE) represents the most aggressive presentation. Robot-assisted laparoscopy represents an important innovation and has opened new perspectives for the treatment of endometriosis, offering numerous advantages especially in the most complex procedures, particularly when extragenital endometriosis diffusely involves pelvic structures including the bowel and the urinary tract [1]. Endometriosis affects the bowel in 30% of DIE cases, and it is usually associated with ovarian and ureteral involvement; therefore, a multidisciplinary team with both general and gynecologic surgeons is required. The goal of endometriosis surgery in these cases is to obtain long-term outcomes without compromising intestinal function. One possible treatment is laparoscopic shave excision, which consists of dissection, keeping it as superficial as possible to avoid compromising bowel integrity [2]. Recent studies have shown that ICG can be useful to evaluate the size and depth of penetration of lesions during endometriosis surgery to understand shaving excision and to prevent a major iatrogenic intestinal complication [3-7].

INTERVENTIONS

Total robot-assisted laparoscopic approach to a DIE case with adnexal, uterine, and intestinal endometriosis, with the presence of a nodular rectal lesion. The excision consisted of several key strategies to minimize iatrogenic rectal injury: CONCLUSION: The approach to DIE, particularly rectal endometriotic lesions, could be more accurate with ICG evaluation of vascular pertinence, in attempt to evaluate shaving feasibility of lesions in endometriosis laparoscopic robotic surgery.

Effect of d-chiro-inositol and alpha-lipoic acid combination on COH outcomes in overweight/obese PCOS women

Insulin resistance (IR) plays a central role in the onset of polycystic ovary syndrome (PCOS). Insulin so insulin-sensitizing like inositols have been proposed as first line therapy. Among them d-chiro-inositol (DCI) seems to improve glucose metabolism and to increase ovulation frequency. Other studies have demonstrated that alpha-lipoic acid (ALA), with its antioxidant role, can also improve endocrine and metabolic profile of PCOS patients especially with familial diabetes. This a retrospective observational study with the aim to evaluate possible advantages of an integrative preparation combining DCI 500 mg and ALA 300 mg in overweight/obese PCOS patients with or without diabetic relatives who underwent IVF. Twenty PCOS patients who were taking the integrative preparation underwent controlled ovarian hyperstimulation in our center. The group with diabetic relatives tended to have a lower dose of gonadotropin, shorter stimulation days, higher number of MII oocytes, and higher number of fertilized oocytes. A combined regimen of DCI and ALA could be an interesting strategy in overweight PCOS patients with familial diabetes underwent ART.

Desire for parenthood at the time of COVID-19 pandemic: an insight into the Italian situation

Purpose: To evaluate the impact of the COVID-19 pandemic lifestyle change on couples of reproductive age and on their desire for parenthood.Materials and methods: A quantitative correlational research study, based on a web survey, was conducted among Italian men and women in heterosexual stable relationships, aged between 18 and 46 years. The self-administered Italian version questionnaire was created using Google Forms and posted on chats and social networks.The mood of participants before and during the quarantine was assessed using a scale from 1 to 10 (1 = no wellbeing; 10 = total wellbeing). Couples' quality of life and their reproductive desire were evaluated.Results: 1482 respondents were included: 944 women (63.7%) and 538 men (36.3%). A significant trend toward reduced mean wellbeing scores during the quarantine, compared to before, was found (p < .01). From 18.1% participants who were planning to have a child before the pandemic, 37.3% abandoned the intention, related to worries of future economic difficulties (58%) and consequences on pregnancy (58%). Of 81.9% who did not intend to conceive, 11.5% revealed a desire for parenthood during quarantine than before (p < .01), related to will for change (50%) and need for positivity (40%). 4.3% of these actually tried to get pregnant. Stratifying by age, a trend toward older ages was found in the desire for parenthood before and during the COVID-19 pandemic (p < .05).Conclusions: COVID-19 pandemic is impacting on the desire for parenthood. It is unknown whether these findings will result in a substantial modification of birth rate in the near future.

Sperm morphology: What implications on the assisted reproductive outcomes?

OBJECTIVE

To evaluate the impact of sperm morphology (SM) on laboratory and pregnancy outcomes in conventional intracytoplasmic sperm injection (c-ICSI) cycles, using the egg donation model to minimize female confounding variables.

MATERIALS AND METHODS

We retrospectively collected data of oocyte donation cycles from October 2016 to February 2020. Median seminal parameters, total (1-2-3PN) fertilization rate (FR), 2PN FR, cleavage rate (CR), implantation rate (IR), pregnancy rate (PR), miscarriage rate (MR), and live birth rate (LBR) were collected. The study population was divided into three groups: Group 1 with SM < 4%, Group 2 with SM between 4% and 6%, and Group 3 with SM > 6%.

RESULTS

Of 741 fresh ICSI cycles and 4507 warmed oocytes were included. Male age was 46.0 (31.0-72.0) years, and recipients' age was 44.0 (29.0-54.0) years. Normal SM was 5.0% (1.0%-15.0%). Male age was negatively correlated with normal SM (P = .002; Rho -0.113). Oocyte survival rate was 83.3% (16.7%-100.0%). Total FR was 75.0% (11.1%-100.0%), 2PN FR was 66.7% (11.1%-100.0%) %, and CR was 100% (0.0%-100%). Comparing samples with SM > 6% and those with SM < 4%, 2PN FR was significantly higher in the first group (P = .04). No significant associations were found among groups in terms of CR. IR was 27.7%, resulting significantly higher when normal SM was > 6% (P < .01). Clinical PR was 36.0%, MR was 23.9%, and LBR was 25.9%. PR and LBR were significantly higher in samples with normal SM > 6%, compared to other groups (P = .02 and P < .01, respectively).

CONCLUSIONS

Although c-ICSI technique allows the embryologist to select the best quality spermatozoa, male factor plays a key role in achieving successful assisted reproductive outcomes. Normal SM has been shown to have implications not only for laboratory outcomes, in terms of fertilization, but also for clinical findings, as regards implantation, pregnancy, and live birth.

Can cytomegalovirus infection affect male reproductive function? Results of a retrospective single-centre analysis

Our objective was to investigate whether the chronic cytomegalovirus (CMV) infection can affect semen parameters in men with couple infertility and to assess the impact of male CMV infection on the reproductive outcomes of CMV-seronegative women suffering from tubal factor. Group 1 included CMV IgG-seropositive men, Group 2 CMV IgG-seronegative patients. Seminal parameters, two-pronuclear (2PN) fertilization rate (FR), 1-2-3PN FR, cleavage rate (CR), miscarriage rate (MR), pregnancy rate (PR) and live birth rate (LBR) were collected. Two hundred and twenty-two men were included: 115 (51.8%) in Group 1 and 107 (48.2%) in Group 2. There was reported a low trend towards higher sperm concentration/ml, total sperm count and viability in CMV IgG-seronegative males, compared to CMV IgG-seropositive (p > .05). Semen volume, pH, motility and normal sperm morphology were similar among groups. Considering the subgroup of men, partners of CMV IgG-seronegative females, 65 couples (29.2%) were selected. Median 2PN FR was 67%, total FR 83%, CR 100%, PR/cycle 26.2%, MR 10.8%, LBR/cycle 15.4%. No significant differences were found regarding the reproductive outcomes between CMV IgG-seropositive men and those seronegative. CMV did not seem to play a key role in male reproductive function, as well as in influencing sperm fertility potential in the assisted reproductive outcomes.

Blood plasma miR-20a-5p expression as a potential non-invasive diagnostic biomarker of male infertility: A pilot study

BACKGROUND

Recently, alterations in miRNAs expression profile in semen have been linked to damaged spermatogenesis, suggesting miRNAs could be used as potential infertility biomarkers. In previous animal studies, miR-20a-5p was found to be down-expressed in low motile spermatozoa, implying its potential target of genes associated with cell apoptosis.

OBJECTIVE

To investigate miR-20a-5p expression in blood plasma of patients suffering from non-obstructive azoospermia (NOA), compared to normozoospermic controls.

MATERIALS AND METHODS

Between January 2018 and December 2019, from 52 infertile couples eligible for the study, 24 couples were finally enrolled in this monocentric observational prospective pilot study. Patients were included into two groups: Group 1 comprised men with NOA (n = 14) and Group 2 fertile men partners of women with female tubal factor infertility (n = 10). All NOA patients underwent testicular sperm extraction. The expression of circulating miR-20a-5p in plasma samples was assessed by RT-qPCR. A relative quantification strategy was adopted using the 2^-ΔCq method to calculate the target miR-20a-5p expression with respect to miR-16-5p as endogenous control.

RESULTS

Median blood plasma miR-20a-5p was significantly higher in patients affected by NOA (0.16 2^-ΔCt , range: 0.05-0.79 2^-ΔCt ) than in fertile controls (0.06 2^-ΔCt , range: 0.04-0.10 2^-ΔCt ), P < .001. MiR-20a-5p was positively correlated with follicle-stimulating hormone (FSH) (r_rho  = -0.490, P = .015) and luteinizing hormone (LH) (r_rho  = -0.462, P = .023), and negatively correlated with serum total testosterone (TT) (r_rho  = -0.534, P = .007) and right and left testicular size (r_rho  = -0.473, P = .020 and r_rho  = -0.471, P = .020, respectively). Successful sperm retrieval (SR) rate was 50.0%. Median value of miR-20a-5p did not differ significantly among patients with successful SR and those with negative SR. Testicular histological examination showed: hypospermatogenesis in 6/14 (42.8%), maturation arrest in 4/14 (28.6%), sertoli cell-only syndrome in 4/14 (28.6%). No significant differences in miR-20a-5p were found between histopathological patterns (P > .05).

CONCLUSIONS

MiR-20a-5p could represent a novel non-invasive diagnostic biomarker of male infertility.

Hepatitis B Surface Antigen Seropositive Men in Serodiscordant Couples: Effects on the Assisted Reproductive Outcomes

Purpose

To evaluate the influence of hepatitis B virus (HBV) infection in men of serodiscordant couples on the reproductive outcomes.

Materials and Methods

A total of 134 infertile couples were included in this retrospective single-center cohort study. Sixty-six couples had hepatitis B surface antigen (HBsAg)-seropositive men and seronegative partners, while 68 couples were controls with both seronegative men and women. Overall, 134 fresh in-vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) treatments were performed. As the main outcome measures, on the day of the fresh IVF/ICSI cycle, we assessed seminal parameters Before and after sperm preparation techniques. Two-pronuclear (2PN) fertilization, 1-2-3PN fertilization, cleavage, miscarriage, pregnancy and live birth rates were collected.

Results

No significant differences were found between groups in terms of oocytes retrieved, oocytes injected and embryos obtained (p=0.64, p=0.97, and p=0.40, respectively). The 2PN fertilization rate (FR) was comparable among groups (p=0.51). The 1-2-3PN FR was significantly lower in the HBsAg group than in the control group (66.6% vs. 69.7%, respectively). The clinical pregnancy per cycle, implantation, miscarriage and live birth rate were comparable between the HBsAg group and the control group. The median sperm concentration/ml and total sperm count, measured at baseline and after sperm preparation, was comparable between groups (p>0.05). There was a trend toward significant lower progressive motility (35.0% vs. 55.0%; p<0.05) in the HBsAg group at baseline and after sperm preparation (p<0.05).

Conclusions

HBV infected men have the same chance to became father, compared to seronegative patients.

Severe bowel incarceration in an eight-millimeter left-lateral trocar site after robot-assisted laparoscopic colposacropexy: A case report

Over the last twenty years, robotic surgery has become an increasingly important form of surgical intervention. However, it can have complications. Trocar site hernia (TSH), also known as port site hernia (PSH), is an uncommon complication, but in the case of bowel incarceration or strangulation it can cause significant morbidity. The lateral trocar sites usually do not need fascial closure, given their low susceptibility to hernia development. In this paper, we present a rare case of an incarcerated TSH from an 8 mm left lateral port after robotic colposacropexy. The patient was a 74-year-old woman with fourth-degree vaginal vault prolapse. She underwent robot-assisted colposacropexy and adnexectomy and was eventually discharged 3 days after surgery, with flatus. A few hours later, the woman developed generalized malaise and acute abdominal pain in the lower left quadrant, with no flatus or bowel movements. CT imaging revealed a small bowel dilatation with a transition point along the left lateral 8 mm trocar site. Laparotomy confirmed an incarcerated ischemic small bowel loop. This required a surgical 40 cm small bowel resection. Although uncommon, TSH is an important clinical entity to recognize after minimally invasive surgery. While it is known that a trocar site port of 10 mm or more does require fascial closure, it is not known whether the same is true of lateral 8 mm sites. Further studies are needed to reconsider the importance of lateral trocar site port fascial closure after robot-assisted surgery.

Vitamin D and Male Fertility: An Updated Review

To date, the key role of vitamin D in male reproductive system has been suggested, since the expression of vitamin D receptors and metabolizing enzymes was demonstrated in the testis and spermatozoa. Nevertheless, a general consensus about the role of vitamin D in male fertility is still debated. The aim of this review is to provide an updated systematic revision of the current available literature, discussing the experimental and clinical evidence on the role of vitamin D in the regulation of testis hormone production, seminal parameters and male fertility. The consequences of vitamin D deficiency on serum levels of testicular hormones have been analysed by several observational and interventional studies, with controversial results. Equally, the experimental researches not were able to state a certain relationship between vitamin D status and testis hormone production. Possible bias, including age, body mass index, and baseline vitamin D status justified the differences among studies. As well as concerning the effect of vitamin D on semen parameters, most of the studies agreed in the possibility that vitamin D might have a positive effect on human male fertility potential, particularly through better sperm motility. Regarding pregnancy outcomes, normal level of vitamin D seems to be related to better pregnancies. However, all the previous studies displayed a wide heterogeneity in study design, population, methodology, and cut off values used for the evaluation of vitamin D status. Future studies are needed to better clarify the exact role of vitamin D on hormonal and seminal panel in both fertile and infertile men.

Successful pregnancy in double factor infertility: Sperm in vitro culture by modified testicular fine-needle aspiration

INTRODUCTION

Infertility may depend up to 27% of couples on both partners. In patients with obstructive azoospermia, testicular fine-needle aspiration represents a good option to retrieve spermatozoa, in order to perform an assisted reproductive treatment. In vitro maturation of testicular spermatozoa could be the better choice of treatment in view of the increased motility, improving fertilization and pregnancy rates.

CASE DESCRIPTION

A 34-year-old azoospermic man and his 33-year-old partner referred for treatment of simultaneous male and female infertility factor. The woman presented a diminished ovarian reserve, with serum follicle stimulating hormone value of 27.15 IU/L. The man underwent trans-rectal and testicular ultrasounds that detected the congenital absence of proximal vas deferens on the right side and the absence of seminal vesicle and distal vas deferens on the left side. We proposed a chance to have their own biological child. The man underwent modified testicular fine-needle aspiration using a 18-gauge butterfly needle. Sperm retrieval was successful with 0.001 × 10⁶ spermatozoa/mL and absence of motility. Testicular sperm suspension was cultured for 24 h to identify sperm viability, achieving 10% of sperm motility. Two metaphase II oocytes were retrieved and processed with intracytoplasmic sperm injection. Clinical pregnancy with live birth was obtained.

CONCLUSION

Performing modified testicular fine-needle aspiration increases successful sperm retrieval. Testicular sperm in vitro culture for 24 h proved to be a real and practical technique to increase sperm motility, in order to select mature and viable spermatozoa and improve successful intracytoplasmic sperm injection outcomes.

Impact of advanced paternal age on the intracytoplasmic sperm injection (ICSI) outcomes in donor egg cycles

Background

The purpose of this study is to assess the impact of paternal age on the oocyte-donation outcomes in intracytoplasmic sperm injection (ICSI) cycles.

Methods

Two hundred and seventy-eight infertile couples were retrospectively involved. Inclusion criteria were: infertility from almost 1 year, normal or sub-fertile seminal parameters, overall oocyte survival rate greater than 85%. Baseline characteristics included male age, recipient age, male body mass index (BMI), smoking, drinking status. Main outcome measures: fertilization rate (FR), cleavage rate (CR), pregnancy rate (PR).

Results

Patients were categorized in group 1 ≤45, group 2 >45 years. A total of 1,724 frozen oocytes were included. After warming, 1,642 oocytes survived. Median overall oocyte survival rate was 100% [interquartile range (IQR), 85-100%]. Median male age was 44±5.60 years (IQR, 31-70 years). Median recipients age was 42±3.62 years (IQR, 29-50 years). Group 1 included 166 men, group 2 112 men. Two hundred and seventy-eight fresh ICSI cycle were performed. "Two-pronuclear" (2PN) FR was 72.6%±0.20%, CR 93.0%±0.16%, PR 39.6%. Miscarriage rate was 25.5%. Live birth rate per cycles was 29.5%. Comparison between group 1, group 2 and ICSI outcomes confirmed an association with FR, resulting 80.0% (IQR, 67.0-83.0%) and 67.0% (IQR, 50.0-80.0%), respectively (P<0.01). There were no significant differences between the two groups with respect to seminal parameters.

Conclusions

It would be recommended more emphasis on the advancing male age when counselling older couples who undergo egg donation program.

Male Inflammatory Parameters Are not Useful to Predict the Outcomes of Intracytoplasmic Sperm Injection: Results from a Cross-Sectional Study

Purpose

The relationship between male systemic inflammation and fertility seems intriguing, but no data about its impact on the assisted reproductive technology outcomes has been reported. Here, we aimed to evaluate the prognostic role of male systemic inflammatory parameters in intracytoplasmic sperm injection (ICSI) outcomes prediction, in couples undergoing an ovum donation program.

Materials and Methods

From January 2016 to December 2017, one hundred-ten couples were considered for this cross-sectional study. Neutrophil-to-lymphocyte ratio (NLR), monocyte-to-eosinophil ratio (MER), platelet-to-lymphocyte ratio (PLR), seminal parameters, fertilization rate (FR), cleavage rate (CR), pregnancy rate (PR) were evaluated. Male patients were divided into Group A with FR ≤70%, Group B with FR >70%.

Results

Overall, FR was 74.5%, CR 90.9%, PR 41.8%. Group A included 43 patients, Group B 67 men. Group A showed a median NLR of 1.55, PLR of 106.09, MER of 2.33. Group B reported a median NLR of 1.64, PLR 109.0, MER 2.76. We found no statistically differences between two groups with respect to NLR, PLR, MER (p=0.90, p=0.70, p=0.96, respectively). The age-adjusted linear regression analysis demonstrated only a relationship between NLR and sperm motility count (r=−0.02; p<0.05). Using the univariate logistic regression analysis, we found no significant associations.

Conclusions

We did not find any relationship between ICSI outcomes and male inflammation parameters.

Relevance of testicular histopathology on prediction of sperm retrieval rates in case of non-obstructive and obstructive azoospermia

Introduction:

The aim of our research was to establish the relevance of testicular histopathology on sperm retrieval after testicular sperm extraction in patients with non-obstructive azoospermia and in patients with obstructive azoospermia, who already underwent a previous failure testicular fine needle aspiration.

Methods:

We evaluated a total of 82 azoospermic men, underwent testicular sperm extraction, referring to the Assisted Reproductive Technology Centre of the University of Florence, Italy between January 2008 and March 2017. A general and genital physical examination, scrotal and trans-rectal ultrasound, semen analysis, hormone measurements, including follicle-stimulating hormone, luteinizing hormone and total testosterone, were collected.

Results:

Successful sperm retrieval was obtained in 36 men of total (43.9%). Successful sperm retrieval was 29.5% in non-obstructive azoospermia patients, while men with obstructive azoospermia, who, underwent a previous failure testicular fine needle aspiration, had sperm retrieval in 86% of cases. Mean luteinizing hormone was 6.55 IU/L, total testosterone 4.70 ng/mL, right testicular volume 13.7 mL and left testicular volume 13.6 mL. Mean Follicle-stimulating hormone was 13.45 IU/L in patients with negative sperm retrieval and 8.18 IU/L in men with successful sperm retrieval. According to histology, 20.7% had normal spermatogenesis, 35.3% hypospermatogenesis, 35.3% maturation arrest and 8.5% Sertoli cell-only syndrome. Successful sperm retrieval was 88.2% in patients with normal spermatogenesis, 24.1% in the maturation arrest group and 48.27% in patients with hypospermatogenesis, while negative sperm retrieval was reported in Sertoli cell-only syndrome patients. Seven cases with maturation arrest showed a successful sperm retrieval.

Conclusion:

Testicular histopathology after testicular sperm extraction offers important information on prediction of sperm retrieval and can guide the surgeon in choosing the more suitable therapeutic practice.
