The present study aimed to clarify the phenomenon of presence of larger than normal follicles (OVGF) in female dromedary camels. Females with OVGF (n=125) were examined by manual palpation and ultrasonography. Accordingly, the OVGF were subdivided into those with thin walls and clear hypoechogenic content (OVGF-TH, n=18) and those with thick walls and fibrous trabeculae (OVGF-TK, n=107). Transvaginal follicle aspiration was performed in females with OVGF and from a control group with growing follicles (1-2 cm in diameter, GF group, n=5). Serum was collected at the same time of follicle aspiration and analyzed for Follicle-stimulating hormone (FSH), luteinizing hormone (LH), progesterone (P4) and estradiol-17β profiles (E2). The follicular fluid (FF) was analyzed for E2 and P4. The results showed that mean E2 concentration in FF and serum were lower in OVGF-TH and OVGHTK groups than in the GF group (P < 0.05). Difference between OVGF-TH and OVGH-TK groups was not significant. P4 in FF did not significantly differ among groups. Positive correlation was found between E2 in FF and E2 in serum (r = 0.495, r = 0.03). Mean FSH concentration in serum was higher in OVGF-TH and OVGH-TK groups than in the GF group (P = 0.03). Mean LH concentration was non-significantly (P=0.1) greater in OVGF-TH and OVGH-TK groups than in the GF group. In conclusion, female dromedary camels with OVGF had endocrine characteristics differed from camels with no OVGF. It seems that the high FSH and/or LH concentration(s) stimulated the continuing growth of the developing follicles to reach these large sizes, suggesting that the phenomenon of OVGF in camels is a pathological finding.

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.

The plasma concentrations of luteinizing hormone (LH) and estrogens (E) were determined for 12 sows, from a herd with a history of postweaning anestrus, from the day of weaning to 32 days after weaning (trial I). A linear increase in plasma LH and E was observed in six sows which remained in anestrus (LH, 0.32–0.47 ng/ml; E, 16.1–24.7 pg/ml). These concentrations were similar to those observed in cycling sows during diestrus. In the remaining sows concurrent peaks of LH and E were observed during proestrus and estrus. In a second trial, two groups each of five sows were treated with a single injection of pregnant mare’s serum gonadotropin (PMSG, 1500 IU) or steroids (estradiol-17β, 1 mg plus progesterone, 2 mg) on the day after weaning. The plasma concentrations of LH and E for 10–12 days after weaning were compared with those of five untreated control sows. In the PMSG-treated group, concurrent peaks of LH (4.7 ± 0.5 ng/ml) and E (121 ± 41 pg/ml) were observed at estrus. The control group produced a lower LH peak at estrus (1.5 ± 0.4 ng/ml) which was not accompanied by a rise in plasma E. No consistent secretory pattern for plasma LH and E was observed in the steroid treatment group.

Background: Coenzyme Q10 (CoQ10) and Lepidium sativum (LS) have therapeutic effects on infertility. Objective: To evaluate the combined effects of LS and CoQ10 on reproductive function in adult male NMRI mice. Materials and Methods: Eighty three-months-old male mice (35–40 gr) were divided into four groups (n = 10/each): control (treated with water), CoQ10-treated (200, 300, and 400 mg/kg/body weight), LS-treated (200, 400, 600 mg/kg/body weight), and co-treated (LS [600 mg/kg/body weight] + CoQ10 [200 mg/kg/body weight]) groups. Serum testosterone, luteinizing hormone, follicle-stimulating hormone, and gonadotropin realizing hormone (GnRH) levels were measured using ELISA method. The sperm quality was assessed using Sperm Class Analyzer® (SCA) CASA system and GnRH mRNA expression levels were evaluated by real-time polymerase chain reaction. Results: The number of sniffing and following behavior was significantly higher in LStreated (400 and 600 mg/ml/body weight) groups than the control group (p = 0.0007 and p = 0.0010, respectively). The number of mounting and coupling behaviors was significantly higher in the CoQ10 (300 and 400 mg/ml/body weight)-treated animals than the control group (p = 0.0170 and p = 0.0006, respectively). Co-treatment of CoQ10 (200 mg/ml/body weight) and LS (600 mg/ml/body weight) significantly increased all aspects of sexual behaviors as well as the levels of serum testosterone (p = 0.0011), luteinizing hormone (p = 0.0062), and follicle-stimulating hormone (p = 0.0001); sperm viability (p = 0.0300) and motility (p = 0.0010); and GnRH mRNA levels (p = 0.0016) compared to the control group. Conclusion: The coadministration of CoQ10 and LS significantly improves the activity of the hypothalamic-pituitary-gonadal axis and enhances the reproductive parameters in adult male mice. Key words: Lepidium sativum, Coenzyme Q10, Infertility, Male reproductive function.

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.
