“…In our study, the azoospermia rate was 10.3% in all patients and 20.0% among the patients with abnormal sperm parameters. Karabulut et al evaluated the patients admitted to three infertility clinics in Turkey, and the azoospermia rate was 5.85% among the 9,733 patients in that study (18.3% of patients with abnormal sperm parameters) [20].…”

Objective: the aim of this study is to determine the prevalence of male factor infertility with the clinical patterns of patients in our region. Materials and methods: this is a descriptive retrospective study of 406 infertility cases presented at our urology clinic from February 2018 to February 2019. We assessed hormone and physical examination data, semen analysis results, the contribution of male and female factors to infertility, and types of infertility (i.e., primary or secondary). Results: the age of the male patients ranged from 18 to 50 years, with a mean of 30 ± 5 years. Asthenozoospermia was the leading cause of male factor infertility in 77 patients (19%). Male factors as the sole cause of infertility were found in 185 (45.6%) couples. Female factors as the sole cause were found in 32 couples (7.9%). Primary infertility was determined in 314 (77.3%) patients, and 92 (22.7%) had secondary infertility. Conclusion: according to our results, the male infertility rate was high among couples reporting infertility. Couples should be informed about the causes of infertility, which may be due factors attributed to either sex.

“…Of note, among these published studies, some focused only on females [10–12]. Others exclusively examined males registered at infertility clinics [13, 14]. As such, these studies were based on relatively small groups, unrepresentative of the larger population of infertile people [15, 16].…”

To provide comprehensive estimates of the global, regional, and national burden of infertility from 1990 to 2017, using findings from a 2017 study on the global burden of disease (GBD), we assessed the burden of infertility in 195 countries and territories from 1990 to 2017. DisMod-MR 2.1 is a Bayesian meta-regression method that estimates non-fatal outcomes using sparse and heterogeneous epidemiological data. Globally, the age-standardized prevalence rate of infertility increased by 0.370% per year for females and 0.291% per year for males from 1990 to 2017. Additionally, age-standardized disability-adjusted life-years (DALYs) of infertility increased by 0.396% per year for females and 0.293% per year for males during the observational period. An increasing trend to these burden estimates was observed throughout the all socio-demographic index (SDI) countries. Interestingly, we found that high SDI countries had the lowest level of prevalence and DALYs in both genders. However, the largest increasing trend was observed in high-SDI countries for females. By contrast, low-SDI countries had the largest increasing trend in males. Negative associations were observed between these burden estimates and the SDI level. The global disease burden of infertility has been increasing throughout the period from 1990 to 2017.

“…Human studies that examined the effect of cryopreservation on sperm OS were performed on ejaculated spermatozoa but not testicular (Karabulut et al., 2018; Moubasher, El Din, Ali, El‐sherif, & Gaber, 2013). There remains a need to evaluate the procedures used in severe male factor infertility and their impact on ICSI outcomes, including the cryopreservation procedure (Sun et al., 2017).…”

Testicular tissue oxidative stress in azoospermic patients: Effect of cryopreservation

et al. 2020

This study evaluated oxidative stress (OS) in human testicular tissue in obstructive (OA) and nonobstructive azoospermia (NOA) before and after cryopreservation. Azoospermic patients were subjected to surgical sperm retrieval (SSR) and cryopreservation. Assay of catalase activity (CAT) and malondialdehyde level (MDA) using colorimetric methods was done. The number of retrieved spermatozoa and the Johnson score were assessed in fresh testicular samples. The study included 21 OA (group A) and 16 positive sperm retrieval (group B, positive NOA). The basal CAT activity in the positive NOA group was significantly higher than that in the OA group. Basal MDA level was also significantly higher in NOA than in OA group. CAT activity and MDA level correlated negatively with the mean number of retrieved spermatozoa. After cryopreservation, there was a significant increase in CAT activity in OA, while there was no significant difference in MDA level in both OA and positive NOA. We concluded that patients with NOA seem to have increased testicular OS compared to OA. The extent of OS correlated negatively with spermatogenesis grade. Testicular tissue of patients with OA seems to withstand OS induced by cryopreservation more than NOA.
