“…About 15% of OBGYN groups stated they would perform sperm extraction procedures themselves, which is consistent with a recent study by Nassiri et al (20) of 225 community infertility clinics across the country, finding that postvasectomy sperm retrieval was offered by 9.4% of REIs. We echo many of the same concerns brought by Nassiri et al (20) regarding these data. Reproductive urologists are best-equipped to properly assess male factor infertility, appropriately select the patient and surgical approach for sperm retrieval, and medically optimize the patient before sperm extraction.…”

Objective: To investigate internet search results available to couples searching for a male factor infertility specialist. Design: Cross-sectional. Setting: Online search engine. Patient(s): The phrase ''male infertility specialist '' was searched in Google for 50 states and Washington D.C. The top 10 results (i.e., first page) of each search were evaluated for website content. Intervention(s): None. Main Outcome Measure(s): The first page of each search was evaluated for provider type (urology vs. obstetrics and gynecology), level of training (fellowship vs. none), male factor fertility information provided, and procedures offered. We compared search position rank (1-10) to determine the likelihood of finding an urologist versus a practitioner in obstetrics and gynecology. Result(s): A total of 419 results were identified; the majority were obstetrics and gynecology-related (N ¼ 229, 54.7%). Urology-related results appeared higher than obstetrics and gynecology-related results (median, 4 vs. 5). Andrology fellowship-trained urologists were identified in 153 (36.5%) results. Among 229 obstetrics and gynecology results, 152 unique practices were identified. A small portion (N ¼ 38, 16.6%) of these practices had a fellowship-trained urologist identified on the website. Most obstetrics and gynecology websites did not mention vasectomy reversal (N ¼ 116, 76.3%) or varicocele repair (N ¼ 93, 61.2%). A minority of practices offered referral to urologists for sperm extraction (N ¼ 23, 15.1%) or offered sperm retrieval themselves (N ¼ 23, 15.1%). Conclusion(s):When searching online for a male factor infertility specialist, most results identified obstetrics and gynecology physicians. A large proportion of obstetrics and gynecology websites lacked information on male factor fertility treatments and did not offer these treatments. These data indicate the need for a more robust online presence of male reproductive urologists to optimize online access. (Fertil Steril Rep Ò 2020;1:227-32.

“…Сбор анамнеза, физикальное обследование, использование визуализирующих методов (ультразвукового исследования, компьютерной и магнитно-резонансной томографии и др.) позволяет диагностировать ряд заболеваний, влияющих на фертильность мужского населения [4,5]. Однако главное место в диагностике принадлежит исследованию эякулята [6].…”

Background. There are not enough publications devoted to the study of erythropoietin in human sperm. According to the results of these studies, the erythropoietin takes part in the regulation of spermatogenesis, affecting the synthesis of hormones, in particular steroid ones. Currently, the physiological and pathogenetic effects of erythropoietin on human ejaculate have not been thoroughly studied. In this regard, the study of this protein in the ejaculate in patients with diseases of the male reproductive system, as well as in their absence, is relevant.The study objective is to determine the concentration of erythropoietin in ejaculate samples of healthy and men with oligoastenozoospermia.Materials and methods. Samples of ejaculate of 52 men of reproductive age were examined. The ejaculate was examined using the SQA-V sperm analyzer (MES, Israel). According to the results of the study, two groups were identified: the main group (n = 18) with reduced fertility and the control group (n = 34) with normal spermogram indicators. In seminal plasma samples, the concentration of erythropoietin was determined by solid-phase enzyme immunoassay using the test system “Erythropoietin-IFA-BEST” (A-8776) (Vector-best LLC, Russia).Results. Erythropoietin was detected in all ejaculate samples, the results ranged from 9.37 to 193.95 mME / ml and varied 20.7 times (p = 0.3). The median concentration in the main group was 64.49 mME / ml (41.96; 118.16 mME / ml) and 1.36 times higher than the results of the comparison group, which were 47.16 mME / ml (18.15; 90.94 mME / ml). No statistically significant regularities were found between the concentration of erythropoietin and the indicators of ejaculate fertility (r <|0,3|).Conclusion. In oligoastenozoospermia, there is a tendency to increase the content of erythropoietin in the seminal plasma, which requires further research, taking into account a more detailed stratification of the groups examined for reasons that caused a decrease in the number of spermatozoa.
