Diabetes mellitus (DM) is a complex metabolic disease and it is also closely associated with a reduction in fertility in male patients. The purpose of the present study was to investigate the antidiabetic effect of carvacrol (CRV), as a potent antioxidant, on the numbers of germ cells and Sertoli cells in testicular tissue, and the messenger RNA (mRNA) and protein expression of some genes involved in spermatogenesis, including luteinizing hormone/choriogonadotropin receptor ( LHCGR), follicle-stimulating hormone receptor ( FSHR), and steroidogenic factor 1 ( SF-1), as well as hormones such as luteinizing hormone (LH), follicle-stimulating hormone (FSH), testosterone (T), and insulin. Adult male Wistar rats ( n = 32) were randomly divided into four groups (eight animals per group), including healthy control that received 0.2% Tween 80, diabetic control group, the diabetic group treated orally with CRV (75 mg/kg), and CRV group that received orally CRV (75 mg/kg). The duration of the treatment period lasted 8 weeks. In the diabetic group, the numbers of Sertoli cells and germ cells were significantly decreased, while the treatment with CRV prevented the degree of the damage to the cells mentioned earlier. CRV administration elevated the concentrations of insulin, T, FSH, and LH. Moreover, treatment with CRV significantly enhanced the levels of the mRNA and protein expression of SF-1, LHCGR, and FSHR. According to the obtained results, CRV administration could prevent the deleterious effects of DM on testicular germ cells, and it increases the levels of hormones and some essential genes, such as SF-1, LHCGR, and FSHR, involved in the process of spermatogenesis.

The present study was designed to investigate the antioxidant property of l-carnitine (LC) on serum levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH), testosterone (TH) and testis oxidative stress in streptozotocin (STZ)-induced diabetic rats. The rats were divided into the following groups: group I, control; group II, LC 100 mg/kg/d; group III, diabetic; and groups IV to VI, diabetic rats treated with 50, 100, and 200 mg/kg/d of LC, respectively. Daily injections were given intraperitoneally for 7 weeks. At the end of experimental period, after sacrificing the rats, FSH, LH, TH, total antioxidant capacity (TAC), malondialdehyde (MDA), glutathione (GSH), catalase (CAT), mitochondrial function (MTT), protein carbonyl (PC), and reactive oxygen species (ROS) levels were measured. STZ caused an elevation of MDA, ROS, and PC ( P < .001) with reduction of GSH, CAT, TAC, and MTT ( P < .001) in the serum levels. Group VI had significantly increased FSH, LH, and TH levels versus the untreated diabetic group ( P < .001). Although groups V and VI significantly decreased MDA ( P < .001), PC ( P < .01), and ROS ( P < .01) compared with the untreated diabetic group; only in group VI, the activity of GSH ( P < .001), CAT ( P < .01), TAC ( P < .001), and MTT ( P < .001) significantly increased. The results of the present study suggest that LC decreased diabetes-induced oxidative stress complications and also improved serum level of FSH, LH, and TH by reducing levels of lipid peroxidation and increasing antioxidant enzymes.

Background. PCOS is one of the most common endocrinological pathologies in women of reproductive age, manifested by a wide range of clinical manifestations. There are many unresolved issues related to the pathogenesis, diagnosis and treatment of this pathological condition in different periods of reproductive age. Aim the objective of the study was to identify the features of the functioning of the pituitary-ovarian system in women with PCOS at different periods of reproductive age. Methods. Study was performed in 20172019 at the FSPSI SCFHHRP, and involved women aged 1845 years. The study groups included women (a group of women with PCOS and a control group) in the follicular phase from 1 to 12 days of the menstrual cycle. As a result of the survey, a group of 44 women with PCOS and a group of 56 healthy women were formed. PCOS was diagnosed according to ESHRE/ASRM criteria (Rotterdam, 2003). Next, subgroups of women in early reproductive age from 35 to 45 years were formed: a group of women with PCOS (n = 29) and a control group (n = 22). And groups of women in late reproductive age from 35 to 45 years were formed: a group of women with PCOS (n = 15) and a control group (n = 34). Conducted: questionnaire survey, general and gynecological examination, ultrasound examination of the pelvic organs, laboratory tests, statistical data analysis. Results. In women with polycystic ovary syndrome of early reproductive age (1835 years), we detected an increase in the level of testosterone by 2 times, DHEA-S by 1.3 times, 17-OH-progesterone by 2 times, sex steroid-binding globulin by 1.4 times, in comparison with control group. The ratio of luteinizing hormone to follicle-stimulating hormone increased by 52%. In women with polycystic ovary syndrome of late reproductive age (3545 years), we detected an increase in the level of testosterone by 1.5 times, 17-OH-progesterone by 1.9 times, luteinizing hormone by 1.4 times, sex steroid-binding globulin by 1.6 times, in comparison with control group, without any significant differences in DHEA-S. At the same time, the ratio of luteinizing hormone to follicle-stimulating hormone increased by 60%. Conclusion. The hormonal profile of women with PCOS of early and late reproductive period is characterized by series of age-related changes in the pituitary-ovarian system, which should be taken into account in preventive and therapeutic measures.

Diabetes mellitus (DM) is a chronic endocrine disease characterized by persistent hyperglycemia. Oxidative damage, inflammatory cytokines, and apoptotic cell death play a major role in the induction and progression of male testicular damage. Plant-derived phytochemicals such as green coffee (Coffea arabica) can possess antidiabetic effects with little toxicity. The current study is aimed at investigating the therapeutic roles of green coffee in diabetic testicular injury stimulated by high-fat diet/streptozotocin administration. Diabetes mellitus was induced by a high-fat diet and a single dose of streptozotocin (STZ) (35 mg kg-1) in male albino rats. Diabetic animals were orally given two different concentrations of green coffee (50 mg kg-1 and 100 mg kg-1) for 28 days. The levels of testosterone, luteinizing hormone, and follicle-stimulating hormone and parameters of oxidative stress, inflammation, and apoptosis were measured. mRNAs and protein levels were detected quantitatively by real-time PCR and ELISA, respectively. In the diabetic group, the levels of testosterone, luteinizing hormone, and follicle-stimulating hormone showed a significant reduction while they increased significantly after green coffee treatment. A significant increase of antioxidant markers glutathione, superoxide dismutase, catalase, glutathione peroxidase, and glutathione reductase along with decreased levels of lipid peroxides and nitric oxide was observed after green coffee treatment in the diabetic group. Finally, the levels of IL-1β, TNF-α, Bax, and caspase-3 were also decreased in both treated groups (metformin and green coffee) when compared to the diabetic group. We conclude that testicular oxidative impairment induced by a high-fat diet (HFD) and STZ can be reversed by green coffee. Administration of green coffee could represent a promising therapeutic agent which can help the treatment of type 2 DM-induced testicular dysfunction.

A number of medicinal plants have been found to influence the level of reproductive hormones and thus affect fertility in the overall. This work evaluated the effects of ethanol leaf extracts of A. gangetica and A. vogelli respectively on some reproductive system parameters in male Wistar rats. A total of sixteen (16) male albino rats were grouped into four (four rats in each group): group A served as normal control, group B received Immunace (Vitabiotics) group C and D received 400 mg/kg body weight of A. gangetica and A. vogelli extracts respectively. Extracts were administered orally to rats for 21 days, after which they were sacrificed by cervical dislocations and blood samples drawn by cardiac puncture. The effect of the extracts on testosterone, follicle stimulating hormone, luteinizing hormone and semen analysis of the test rats were determined using enzyme linked immunosorbent assay (ELISA) and standard techniques. Data collected were analyzed using Graph pad prism V6 and p values < 0.05 were adopted as significant. There was no significant (p>0.05) change in testosterone, FSH and luteinizing hormones in the group administered A. gangetica plant extract relative to the control. There was also no visible difference in the testes weight and sperm morphology relative to the control group. In contrast, administration of A. vogelli extract caused significant (p<0.05) decrease in testosterone and follicle stimulating hormone concentrations from: 1.12 ± 0.20 to 0.89 ± 0.05 and 1.41 ± 0.07 to 1.35 ± 0.12 respectively relative to the control group. While significant (p<0.05) decrease in luteinizing hormone (1.71 ± 0.15) was observed relative to the standard drug group (1.76 ± 0.05). A significant (p<0.05) decrease in sperm count and testes weight was also observed in rats treated with A. vogelli extract relative to the normal control.The results suggest that, A. vogelli extract may cause decreased fertility in male albino rats and could be developed further into potent male contraceptives. A. gangetica on the other hand, had no effect on male reproductive hormones.
