Amelioration of ethanol reprotoxicity by aqueous Spinacia oleracea extract in male rabbits Oryctolagus cuniculus

Spinacia oleracea “Spinach” is a plant rich in antioxidants; it leads to improved male reproduction. For this reason, the objective of this study is to evaluate the effect of the aqueous extract of this plant on the fertility of adult male rabbits after their administration with ethanol. The rabbits were divided into four groups: control group, group treated with 150 mg / kg / day of aqueous Spinacia oleracea extract (Ep), group treated with 40% ethanol (EtOH), and group treated with 150 mg / kg / day of aqueous Spinacia oleracea extract + 40% ethanol (Ep + EtOH), for a period of five successive weeks. Treatment was administered orally. After sacrificing the rabbits, the reproductive organs were removed and weighed. Certain sperm parameters (concentration, mobility, speed, and vitality), the testosterone level and the weight of the testes and epididymis were assessed. The results obtained showed a decrease in the concentration, mobility, speed and vitality of sperm, accompanied by a decrease in testosterone levels, and in the weight of the testes and epididymis in the group treated with ethanol, on the other hand, treatment with aqueous Spinacia oleracea extract revealed an increase in these parameters. In conclusion, treatment with aqueous Spinacia oleracea extract can repair the damage caused by ethanol.

Quality of ejaculate of male patients with type 2 diabetes mellitus (DM), vaccinated with GamCovidVac (Sputnik V)

Background: New coronavirus infection (Covid-19) in patients with diabetes type 2 mellitus (DM) often has severe clinical course and manifestation. This comorbidity is a reasonable indication for vaccination. Male patients are often concerned about the vaccination impact on their fertility, so the current research of this issue seems to be essential and relevant.Aims: To evaluate the quality of ejaculate in type 2 diabetes mellitus (DM) patients, vaccinated by GamCovidVac (Sputnik V).Materials and Methods: The pilot observational prospective study included 30 males with type 2 diabetes mellitus (DM). The study continued from February 2021 till June 2021. The research design involved medical history analysis, glycated hemoglobin (HbA1c) tests, total testosterone level in blood measurement, semen analysis (sperm count test). Group comparison was performed by Wilcoxon Signed Ranks Test. The differences were considered statistically significant at p<0.05.Results: After vaccination 19 patients (63%) demonstrated a temperature rise which lasted for 2 days; 26 patients (87%) complained of tenderness in the injections site which lasted up to 5 days. Though a few patients reported general somatic side effects after the vaccination, there have been no statistically significant deviations in sperm count, viability, function and morphology. The levels of glycated hemoglobin and total testosterone remained unchanged.Conclusion: The study revealed no negative impact of GamCovidVac on ejaculate quality, total testosterone level and compensation of carbohydrate metabolism.

Impacts of Androgen Abuse and Overtraining on Endocrine Profile in Bodybuilders

Abuse of androgens and overtraining expose bodybuilders to multifactorial stress influences related to endocrine activity. Endocrine responses in 23 bodybuilder athletes were investigated after a strength training period, during which they were taking high doses of androgenic-anabolic steroids. Serum concentrations of TSH, T3, and T4 were unchanged significantly. Serum LH and FSH concentrations decreased dramatically (P<0.05). In addition, low mean concentration of serum testosterone was recorded, with more substantial reduction in participants of elder ages. The multiple regression model used in this analysis supported this inference. On the other hand, a positive association was observed between levels of blood lipids (total cholesterol, triglyceride) and the outcome predictor (mean serum testosterone level). The results also suggested a negative correlation between testosterone level and each of age and HDL level. The current study shows that excessive bodybuilding exercise has an impact on the hypothalamic–pituitary–thyroid (HPT) axis in top-level athletes. Also, simultaneous usage of anabolic steroids induces extreme shifts in the hypothalamic-pituitary–gonadal (HPGA) axis, which is reflected as changes in testosterone level, development of the overtraining syndrome, and adverse influences on hormonal control.

Erectile dysfunction and testosterone levels prior to COVID-19 disease: What is the relationship?

Objective: We aimed to investigate the relationship between COVID-19 and Erectile Dysfunction (ED) and the effect of serum testosterone level on the disease prognosis. Methods: Between April-December 2020, 70 patients who were admitted with a complaint of ED after having COVID-19 and whose serum testosterone level was checked for varicocele, premature ejaculation, and infertility reasons before COVID-19. The patients filled the International Index of Erectile Function (IIEF-5) and their testosterone level was checked. The questionnaire was arranged to assess the first month before COVID-19 and after COVID-19. Testosterone levels of the patients before and after COVID-19 were compared. The relationship between testosterone levels and hospitalization in the intensive care was evaluated.Results: It was revealed that testosterone levels and IIEF-5 scores after COVID-19 in all patients were statisticaly and significantly different compared to the period before COVID-19 (p < 0.05). Testosterone levels of patients in need of intensive care were significantly higher than those without any need of intensive care (p < 0.05).Conclusions: Our study has presented that COVID-19 may cause ED and high testosterone levels increase the rate of hospitalization in the intensive care by intensifying the disease.

The Potency of Anadara nodifera Shell as Natural Testosterone Booster for Male Canary (Seriunus canaria)

Anadara clam shell contains high Zinc. This microelement is recognised as acting natural aromatase blocker (NAB) that capable of boosting testosterone level. The aim of this study was to evaluates the testosterone level of Canaries following Anadara nodifera administration. Adult male Canaries (n = 27) were group into 3 with 9 repetition of each i.e T0 [control, was given by Carboxymethyl Cellulose Sodium (Na-CMC)], T1 (Zinc Sulphate 0.013 mg/30 g BW), and T2 (NAB 0.3 mg/30 g BW). The T2 treatment was NAB or shell powder of Anadara nodifera which was diluted 1:1 in Na-CMC. The birds were treated orally for 21 days. The complete blood cell count was performed in a haemo analyser except the erythrocyte was calculated manually in the Improved Neubauer counting chamber. Testosterone level was measured in ELISA. Subsequently gen CYP19 aromatase in syrinx, brain and testis were identified employing IHC and descriptively analysed. The result indicated significant elevated level of testosterone (p<0.05). The expression of CYP19 aromatase receptor was depressed in syrinx, brain and testis. However there was no significant changes on the blood profile (p>0.05). To conclude, Anadara nodifera at 0.3 mg/30 g BW was capable of acting as NAB to promote testosterone level. This was confirmed by the reduction of CYP19 aromatase gene receptors in syrinx, brain and testis. However NAB treatment was not significantly affecting routine blood profile.

Study on effect of hair coat color on various reproductive attributes of Cholistani service bulls

The objective of the present study was to assess the possible effect of hair coat color on various orchidometric, seminal and andrological attributes of black-coated and brown-coated Cholistani service bulls. Adult Cholistani bulls (n= 8) were grouped as black-spotted (n= 4) and brown-spotted (n=4). Semen collection was performed once weekly (2 ejaculates/collection) using artificial vagina (AV) throughout the study period (October-May). Semen samples were evaluated for various physical attributes. Body weight and orchidometric attributes of the bulls were attained using calipers. Blood sampling was performed twice weekly and serum testosterone level was deduced through automated analyzer. The scrotal circumference, Scrotal Skin Fold Thickness and Paired Testicular Volume were significantly higher (P<0.05) in black-spotted Cholistani bulls as compared to brown-spotted bulls. Similarly, the ejaculatory volume (5.8±0.1 mL) and individual sperm motility (63.3±1.4%) were significantly higher (P<0.05) in black-spotted bulls. Percentage of live spermatozoa, and spermatozoa with normal morphology and acrosome was also higher in black-spotted bulls though statistically non-significant (P>0.05). Amongst post-thaw seminal attributes, percentage of live spermatozoa, and spermatozoa with normal morphology and acrosome were significantly higher (P<0.05) in black-spotted bulls. Similarly, serum testosterone level in black-spotted Cholistani bulls (6.9±0.3 ng/mL) was significantly higher (P<0.05) compared to brown-spotted bulls (5.4±0.3 ng/mL). The black-spotted Cholistani service bulls showed substantially better orchidometric and seminal attributes allied with higher serum level of testosterone.
