Abstract
OBJECTIVE To call to attention the often-overlooked aspect of pediatric transgender care: the importance of fertility preservation prior to instituting gender-affirming therapy. The transgender population has long been marginalized by society. Societal stigmata, fear to seek care, and dearth of provider knowledge regarding transgender health issues have caused disparities to widen. Gender-affirming procedures and hormone therapy affect the long-term reproductive potential of transgender individuals. While cost concerns and insurance coverage regarding oncofertility is a prominent area of discussion, the transgender community is often excluded. METHODS Sixteen genetically XY females, followed by their multidisciplinary transgender care teams, were interested in starting hormone therapy due to impending onset and/or progression of puberty. Their physicians were aware of fertility struggles after undergoing hormone therapy and therefore referred to urology. Sperm cryopreservation via open gonadal biopsy, testicular tissue cryopreservation (TTC), and semen sample (when age/maturity-appropriate) were discussed. Though requiring surgery, biopsy/TTC relieves patients of the psychological impact of semen sample production. RESULTS Under IRB approval, 15 patients (median age 12 years, range 10-16 years) underwent TTC (Fig. 1). One patient (aged years) opted for semen sample. All patients had success with spermatogonial stem cells cryopreserved for future patient use. CONCLUSION With more individuals beginning medical and surgical therapy at a younger age, fertility preservation discussions are essential but often overlooked, depriving these individuals the joy of becoming a biological parent. TTC can be safely done in pediatric populations, though research is necessary to expand beyond current experimental stage of tissue development.

Factors predicting successful sperm retrieval in men with nonobstructive Azoospermia: A single center perspective. Health Sci Rep 2022; 5:e727. [PMID: 35899179 PMCID: PMC9304940 DOI: 10.1002/hsr2.727] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2022] [Revised: 06/07/2022] [Accepted: 06/09/2022] [Indexed: 11/06/2022] Open
Abstract
Predicting successful sperm retrieval is essential in counseling infertile men with Azoospermia. Objectives To assess the predictors of successful sperm extraction in men with nonobstructive Azoospermia. Patients and Methods A retrospective study included all patients with nonobstructive Azoospermia from January 2018 to May 2019. Subdivided into two groups, group I (negative sperm retrieval) and group II (positive sperm retrieval). Results A total of 108 patients with a mean age of 36.8 ± 10 years were included. The rate of successful sperm retrieval was 47.2%. Group I included 57 patients (52.8%) with a mean age of 33.98 ± 6.18, and group II included 51 patients (47.2%) with a mean age of 40.04 ± 12.22 (p = 0.008). Follicular stimulating hormone (FSH) levels were significantly higher in group I (18.55 ± 13 vs. 7.97 ± 7.11; p < 0.004). Similarly, in group I, luteinizing hormone was significantly higher (11.4 ± 7.45 vs. 5.9 ± 4.4; p < 0.001). Age and FSH were the independent predictors of successful micro-TESE. Additionally, successful pregnancies were 13.7% of patients, 28.6% of which gave rise to living birth. Conclusion Patients' age and serum FSH are independent predictors of successful sperm retrieval for infertile men with nonobstructive Azoospermia; young patients with high FSH levels could have little chance of sperm retrieval.

Abstract
The aim of this study was to evaluate intracytoplasmic sperm injection (ICSI) outcomes of fresh and cryopreserved sperm via microdissection testicular sperm extraction (micro-TESE) in patients with nonobstructive azoospermia (NOA).From March 2016 to February 2020, a total of 244 men with NOA underwent micro-TESE at the Center for Reproductive Medicine, First Hospital of Jilin University, P. R. China. These cases included 40 patients who underwent 40 ICSI cycles with fresh spermatozoa from micro-TESE (Group A) and 30 patients who underwent 30 ICSI cycles with cryopreserved spermatozoa from micro-TESE (Group B). The characteristics, embryonic development, and ICSI outcomes of patients were compared between groups A and B.Our sperm retrieval rate (SRR) by micro-TESE in patients with NOA was 35.25%. No statistical differences in the patient characteristics and fertilization or quality embryo rates were observed between Groups A and B. Higher miscarriage rates and lower live births were observed in Group B than in Group A (both P < .05).Fresh testicular spermatozoa seem to produce better ICSI outcomes than cryopreserved testicular spermatozoa from patients with NOA in the micro-TESE-ICSI cycle.

Abstract
We performed this study to evaluate the clinical outcomes of microdissection testicular sperm extraction-intracytoplasmic sperm injection (micro-TESE-ICSI) treatment that used fresh or cryopreserved sperm in patients with nonobstructive azoospermia (NOA). A total of 338 NOA patients with 344 consecutive cycles received treatment in the reproductive medicine center of Peking University Third Hospital in Beijing, China, from January 2014 to December 2017. Fresh oocytes and fresh sperm were used in 222 patients with 234 cycles (Group A). Fresh oocytes and cryopreserved sperm were used in 116 patients with 110 cycles (Group B). We compared patient characteristics, embryonic development, and pregnancy outcomes between Groups A and B. There was no statistical difference in the patient characteristics, and no differences were observed with fertilization or quality embryo rates between Groups A and B. The rates of clinical pregnancy and live birth were both higher for Group A than those for Group B (both P < 0.05). In conclusion, fresh testicular sperm appears to produce better ICSI outcomes than cryopreserved testicular sperm in patients with NOA.

Abstract
OBJECTIVE The transgender population has long been marginalized by society. Societal stigmata, fear to seek care, and dearth of provider knowledge regarding transgender health issues has caused disparities to widen. The purpose of this case study is to call to attention the often-overlooked aspect of transgender care: the importance of fertility preservation prior to undergoing therapy. METHODS 13 and 16-year old genetically XY patients presented to a tertiary care facility for gender affirmation. Both self-identified as female since a young age and successfully socially transitioned. Impending onset and/or progression of puberty prompted patients to seek hormonal therapy. Fortunately, physicians in transgender clinic were aware of fertility struggles after undergoing hormone therapy and referred for consultation. RESULTS Sperm cryopreservation via open gonadal biopsy, tissue cryopreservation, and semen sample were discussed. Though invasive, biopsy relieves patients of the psychological impact of sample production and is indicated in pubertal immaturity. After further discussion with patients and parents, the 13-year-old decided to undergo testicular biopsy while the 16-year old opted for semen sample. Both patients had success and their genetic material was cryopreserved for future assisted reproduction. CONCLUSION Gender affirming procedures and hormone therapy affect the long-term reproductive potential of transgender individuals. While cost concerns and insurance coverage regarding oncofertility is a prominent area of discussion, the transgender community is often excluded. With more individuals beginning medical and surgical therapy at a younger age, fertility preservation discussions are essential but often overlooked, depriving these individuals the joy of becoming a biological parent.

Abstract
The live birth rates (LBRs) in men with non-obstructive azoospermia (NOA) undergoing microdissection TESE (mTESE) are under reported, with surgical sperm retrieval rate often used as the primary outcome measure. We analysed longitudinal and cumulative delivery rates following mTESE- intracytoplasmic sperm injection (ICSI) in NOA. Sperm was retrieved in 45% of patients undergoing mTESE. Median male and female age were 42 years (IQR 37-47) and 35 years (IQR 31-38) respectively. A total of 141 ICSI cycles and 23 frozen embryo transfers resulted in 62 pregnancies and 37 LBRs. The longitudinal LBR, crude and expected cumulative delivery rates after five cycles were 15.5%, 48.7% and 71.1%, respectively. Reassuringly, there was no significant difference in pregnancy rate (PR) (p = 0.37) or LBR (p = 0.68) using fresh or frozen sperm or embryo (p = 0.74). Sperm retrieval was significantly correlated with Johnsen score (JS) (p = 0.006) and hypospermatogenesis (HS) (p = 0.04), whilst LBR only significantly correlated with female age (p = 0.04). The longitudinal LBR for a couple embarking on mTESE for azoospermia is only 15.5%, although the cumulative delivery rates are promising. Reassuringly, the outcomes using fresh versus frozen embryos or sperm are comparable. Reporting on delivery rates from a single mTESE procedure are more objective and realistic measures of treatment success in men with NOA.

Abstract
The aim of this study was to evaluate the predictive value of preoperative hormonal levels and pathology, as well as the outcome of microsurgical testicular sperm extraction in patients with non-obstructive azoospermia (NOA), presenting to our clinic for treatment of infertility. The records of 145 men with NOA who underwent microdissection testicular sperm extraction (micro-TESE) between March 2013 and November 2016 were studied. The patient's age, testicular volume, hormonal profile for follicle-stimulating hormone (FSH), luteinizing hormone (LH), and testosterone (TT), and testicular pathology were recorded. The sperm retrieval, the clinical pregnancy and live birth delivery rates were noted. Our testicular sperm retrieval rate was 65.5%. There was no statistical difference in age, testicular volume, or hormonal levels in the TESE-positive and negative groups. Hypospermatogenesis was found in testicular histopathology in 57 of 117 patients (48.7%) who underwent testicular biopsy. Sertoli Cell-Only (SCO) syndrome was seen in 20.5%, Germ Cell Maturation Arrest (MA) in 16.3%, and Atrophy-hyalinization in 14.5%. Seven men had Klinefelter's syndrome (KS), four of whom were TESE-positive. There were no adverse effects of the procedure except for infection at the incision site in one patient. Single intracytoplasmic sperm injection (ICSI) cycles were performed in 92 couples leading to 41 clinical pregnancies and 26 live birth deliveries. Micro-TESE is a safe procedure in experienced hands and provides infertile men with NOA an opportunity to father children. However unselected candidates with NOA should be counselled at the outset that only 17.9% will eventually become biological fathers.

Abstract
Fertility preservation is an area of immense interest in today's society. The most effective and established means of fertility preservation is cryopreservation of gametes (sperm and oocytes) and embryos. Gonadal cryopreservation is yet another means for fertility preservation, especially if the gonadal function is threatened by premature menopause, gonadotoxic cancer treatment, surgical castration, or diseases. It can also aid in the preservation of germplasm of animals that die before attaining sexual maturity. This is especially of significance for valuable, rare, and endangered animals whose population is affected by high neonatal/juvenile mortality because of diseases, poor management practices, or inbreeding depression. Establishing genome resource banks to conserve the genetic status of wild animals will provide a critical interface between ex-situ and in-situ conservation strategies. Cryopreservation of gonads effectively lengthens the genetic lifespan of individuals in a breeding program even after their death and contributes towards germplasm conservation of prized animals. Although the studies on domestic animals are quite promising, there are limitations for developing cryopreservation strategies in wild animals. In this review, we discuss different options for gonadal tissue cryopreservation with respect to humans and to laboratory, domestic, and wild animals. This review also covers recent developments in gonadal tissue cryopreservation and transplantation, providing a systematic view and the advances in the field with the possibility for its application in fertility preservation and for the conservation of germplasm in domestic and wild species.

Abstract
STUDY QUESTION What are the chances of a couple with infertility due to non-obstructive azoospermia (NOA) having their genetically own child by testicular sperm extraction combined with ICSI (TESE-ICSI)? SUMMARY ANSWER Candidate TESE-ICSI patients with NOA should be counselled that, when followed-up longitudinally, only a minority (13.4%) of men embarking for TESE eventually become a biological father. WHAT IS KNOWN ALREADY Data available in the literature are only fragmentary because they report either on sperm retrieval rates after TESE or on the outcome of ICSI once testicular spermatozoa has been obtained, mostly in a selected subpopulation. Unfortunately, reliable data to counsel men with NOA on their chance to become a biological father are still lacking. STUDY DESIGN, SIZE, DURATION This is a retrospective cohort study performed in the Centre for Reproductive Medicine, University Hospital of Brussel, approved by the institutional review board of the hospital. PARTICIPANTS/MATERIALS, SETTING AND METHODS We identified all patients with NOA, based on histology, who had their first testicular biopsy between 1994 and 2009. Patients were followed longitudinally during consecutive ICSI cycles with testicular sperm. The primary outcome measure was live birth delivery. The cumulative live birth delivery rate was calculated, based only on ICSI cycles with testicular sperm (fresh and/or frozen) available for injection. When patients delivered after transfer of supernumerary frozen embryos, this delivery was tallied up to the (unsuccessful) original fresh ICSI cycle. The sperm retrieval rate and pregnancy rate were secondary outcome measures. MAIN RESULTS AND THE ROLE OF CHANCE Among the 714 men with NOA, 40.5% had successful sperm retrieval at their first TESE. In total, 261 couples had 444 ICSI cycles and 48 frozen embryo transfer cycles, leading to 129 pregnancies and 96 live birth deliveries. Crude and expected cumulative delivery rates after six ICSI cycles were 37 and 78%. LIMITATIONS AND REASON FOR CAUTION A retrospective cohort study design was the only way to study the cumulative delivery rate after TESE-ICSI in couples with NOA. Intrinsic limitations are related to the observational study design. WIDER IMPLICATION OF THE FINDING TESE-ICSI is a breakthrough in the treatment of infertility due to NOA, with almost 4 out of 10 (37%) couples having ICSI obtaining a delivery. However, unselected candidate NOA patients should be counselled, before undergoing TESE, that only one out of seven men (13.4%) eventually father their genetically own child. STUDY FUNDING AND COMPETING INTERESTS None declared.

Abstract
PURPOSE To evaluate the viability of frozen embryos generated by intracytoplasmic sperm injection (ICSI) with frozen testicular spermatozoa. METHODS A total of 68 fresh embryo transfer (ET) cycles and 85 subsequent frozen-thawed ET (FET) cycles were grouped according to the source of spermatozoa: fresh testicular spermatozoa (TESE) or frozen-thawed testicular spermatozoa (t-TESE). RESULTS There were no significant differences in the age of female patients, number of oocytes, or fertilization rates in fresh ET cycles with TESE (TESE-fresh ET) versus t-TESE (t-TESE-fresh ET). The rate of embryo survival after thawing (95.7 % vs. 94.0 %) was similar in frozen ET cycles (FET) with TESE (TESE-FET) and with t-TESE (t-TESE-FET). While there were significant differences in the proportion of good quality embryos, no statistical differences were found in the pregnancy or clinical abortion rates between the two groups. Moreover, delivery rates were not significantly different. CONCLUSIONS Although the proportion of good quality embryos was affected by cryopreservation of testicular tissue, embryo survival rate was not. As well, subsequent pregnancy could be achieved successfully via t-TESE-FET cycles. Therefore, FET is not affected by the cryopreservation of testicular tissue, and avoids further oocyte retrieval and TESE procedures.

Abstract
Recent advances in oncology have helped in the survival and cure of increasing numbers of childhood cancer patients and those during their reproductive age period. This has increased the need to improve existing technology, and prompted the search for new technologies, to minimize the gonadotoxic effects of cancer treatment and preserve human fertility. Conservative surgical approaches for cancer treatment have been widely accepted following progress in early detection of cancer and accumulating long-term outcome safety data. Gonadal suppression to increase resistance to cancer treatment by gonadotropin analogues and sex hormones has been suggested. However, while this is unlikely to be effective in males, there is no general consensus on its success in the female. Fertility preservation options for both male and female patients include cryopreservation of embryos, gametes and gonads. While embryo cryopreservation is a well-established and successful technique, there are several obvious limitations. Gamete cryopreservation is very successful in males (sperm freezing) while still experimental in females (oocyte freezing), with growing evidence suggesting its potential success. Gonadal cryopreservation is still in its early stages of experimental development, both in males (testicular tissue cryopreservation and in vitro spermatogenesis) and female (ovarian tissue cryopreservation and in vitro follicular maturation).

Abstract
Objective Determine whether testicular sperm extractions and pregnancy outcomes are influenced by male and female infertility diagnoses, location of surgical center and time to cryopreservation. Patients One hundred and thirty men undergoing testicular sperm extraction and 76 couples undergoing 123 in vitro fertilization cycles with testicular sperm. Outcome Measures Successful sperm recovery defined as 1–2 sperm/0.5 mL by diagnosis including obstructive azoospermia (n = 60), non-obstructive azoospermia (n = 39), cancer (n = 14), paralysis (n = 7) and other (n = 10). Obstructive azoospermia was analyzed as congenital absence of the vas deferens (n = 22), vasectomy or failed vasectomy reversal (n = 37) and “other”(n = 1). Sperm recovery was also evaluated by surgical site including infertility clinic (n = 54), hospital operating room (n = 67) and physician’s office (n = 11). Treatment cycles were evaluated for number of oocytes, fertilization, embryo quality, implantation rate and clinical/ongoing pregnancies as related to male diagnosis, female diagnosis, and use of fresh or cryopreserved testicular sperm. Results Testicular sperm recovery from azoospermic males with all diagnoses was high (70 to 100%) except non-obstructive azoospermia (31%) and was not influenced by distance from surgical center to laboratory. Following in vitro fertilization, rate of fertilization was significantly lower with non-obstructive azoospermia (43%, p = <0.0001) compared to other male diagnoses (66%, p = <0.0001, 59% p = 0.015). No differences were noted in clinical pregnancy rate by male diagnosis; however, the delivery rate per cycle was significantly higher with obstructive azoospermia (38% p = 0.0371) compared to diagnoses of cancer, paralysis or other (16.7%). Women diagnosed with diminished ovarian reserve had a reduced clinical pregnancy rate (7.4% p = 0.007) compared to those with other diagnoses (44%). Conclusion Testicular sperm extraction is a safe and effective option regardless of the etiology of the azoospermia. The type of surgical center and/or its distance from the laboratory was not related to success. Men with non-obstructive azoospermia have a lower chance of successful sperm retrieval and fertilization.

Abstract
Fertility preservation in the male is routinely focused on sperm. In clinical and veterinary settings, cryopreservation of sperm is a widely used tool. However, the goals for male fertility preservation differ between experimental models, maintenance of livestock, conservation of rare species, and fertility protection in men. Therefore very different approaches exist, which are adapted to the specialized needs for each discipline. Novel tools for male fertility preservation are explored targeting immature germ cells in embryonic or immature testes. Many options might be developed to combine germline preservation and generation of sperm ex vivo leading to interesting new perspectives. This review highlights current and future options for male fertility preservation with a special focus on animal models and a consideration of the various disciplines in need of novel tools.

Abstract
Selection for intracytoplasmic sperm injection (ICSI) of viable frozen-thawed testicular spermatozoa obtained from patients suffering from non-obstructive azoospermia is very often long, difficult and sometimes impossible. The purpose of this study was to determine if the use of pentoxifylline (PF) could facilitate this selection in stimulating sperm motility. From January 2000 to December 2004, 108 ICSI cycles with non-obstructive azoospermia were performed. From these 108 cycles, in 64 cycles where no motile spermatozoa were observed or when the time search per spermatozoa was above 20 min, 1.5 mmol/l PF was used for 10 min, whereas the 44 other ICSI cycles were performed using spontaneously motile spermatozoa (control group). In all cases, PF either initiated the motility when no motile spermatozoa were observed, or stimulated the motility, reducing dramatically the time search per spermatozoa. The total fertilization rate was 54.2% versus 66.7% in the control group (P < 0.02). Twenty-nine pregnancies out of the 64 PF cycles (45.3% per cycle) occurred, including 20 deliveries of 23 healthy children and eight ongoing pregnancies, whereas 12 pregnancies were obtained in the control group (27.3% per cycle), including nine deliveries of 13 healthy children. In conclusion, in 100% of cycles pentoxifylline allows the selection of viable frozen-thawed testicular spermatozoa with the same outcome after ICSI as that observed with fresh ejaculated spermatozoa.

Abstract
IVF/intracytoplasmic sperm injection (ICSI) using surgically retrieved spermatozoa (SRS) is a key option in the treatment of severe male infertility. It was aimed to develop a computational model for the prediction of this modality's outcome. A dataset of 113 exemplars, derived from patients who underwent IVF/ICSI with SRS, was retrospectively analysed. The dataset, containing input features maternal age, sperm retrieval technique, type of spermatozoa used, type of male factor and output intrauterine pregnancy, was randomized into a modelling ('training') set of 83 and cross-validation ('test') set of 30. neUROn++, a set of C++ programs, was used to model the dataset using linear and quadratic discriminant function analysis, logistic regression, and neural computation. A 4-hidden node neural network was found to have the highest accuracy, with a test set receiver operator characteristic (ROC) curve area of 0.783. Reverse regression of this neural network showed maternal age to be the most significant feature in predicting pregnancy (P = 0.025), followed by sperm type (P = 0.076). Type of male factor (P = 0.47) and sperm retrieval technique (P = 0.88) did not predict outcome. In summary, a neural network of clinical relevance was found to be superior in terms of IVF/ICSI outcome prediction. Future media deployment is planned.

Abstract
This prospective study evaluated the crude cumulative delivery rate following delayed intracytoplasmic sperm injection (ICSI) using spermatozoa recovered by testicular extraction (TESE) and intentionally frozen in men with non-obstructive azoospermia (NOA). This procedure can be termed 'cryoTESE-ICSI'. This study involved a series of 118 patients who underwent testicular biopsy for diagnosis of NOA in the period from January 1998 to December 2002. Testicular histology confirmed the diagnosis of NOA. Testicular parenchyma was obtained surgically from both testicles under general anaesthesia. Cryopreservation of spermatozoa was performed in 51 of 118 patients (43%). Ninety-nine delayed ICSI procedures were performed. Frozen-thawed suspensions were used in all cycles. Application of pentoxifylline was required to stimulate spermatozoa in 52% of cases. Fertilization, embryo transfer, and ongoing pregnancy rates were 60, 98 and 29% respectively. The crude cumulative delivery rate was 49% after two cycles and 57% after four cycles. A total of 39 healthy children were born in 29 deliveries. Thus, cryoTESE-ICSI is an effective procedure for routine use in patients with NOA. The main advantages of cryoTESE-ICSI are to (i) avoid repeated surgical biopsy, (ii) ensure the availability of spermatozoa when the ovarian stimulation cycle is begun, and (iii) allow programmed biopsy and therefore dissociate it from ICSI.

Abstract
A retrospective cohort study was conducted with an intracytoplasmic sperm injection (ICSI) group and a naturally conceived comparison group. A total of 1655 singleton and 1102 twin ICSI births were studied with regard to perinatal outcome. Control subjects (naturally conceived pregnancies) were selected from a regional registry and were matched for maternal age, parity, place of delivery, year of birth and fetal sex. The main outcome measures were duration of pregnancy, birth weight, Apgar score <5 after 5 min, neonatal complications, perinatal death and congenital malformations. Twin births, when compared with singletons, carry a much higher risk of poor perinatal outcome. For both ICSI singletons and ICSI twins, no significant difference was found between ICSI and naturally conceived pregnancies for all investigated parameters. After excluding like-sex twin pairs, ICSI twin pregnancies were at increased risk for perinatal mortality (OR = 2.74, CI = 1.26-5.98), prematurity (OR = 1.38, CI = 1.10-1.75) and low birth weight (OR = 1.34, CI = 1.06-1.69) compared with spontaneously conceived different-sex twin pairs. In conclusion, the perinatal outcome of ICSI singleton and twin pregnancies was very similar to that of spontaneously conceived pregnancies in this large cohort study. After excluding like-sex twin pairs, ICSI twins were at increased risk for prematurity, low birth weight and higher perinatal mortality compared with the natural conception comparison group.
