Objectives The aim of the study was to evaluate the efficacy of a 4.7 mg deslorelin implant in tom cats. Methods Nine mature male cats were included in the deslorelin group and five cats in the control group. Before the study started, all cats were confirmed to have distinct sexually dimorphic behaviour. Blood samples were taken on the implantation day, at day 7 and at day 15, then monthly, in order to measure serum dihydrotestosterone (DHT) and 17beta(β)-oestradiol concentrations. The deslorelin group (n = 9) was divided into two subgroups: five cats (cats 1–5) were neutered in the postimplantation period during suppression of sexually dimorphic behaviour, and four cats (cats 6–9) were neutered after re-expression of sexually dimorphic behaviour. The control group cats (n = 5) were castrated without administration of the implant. Results Sexually dimorphic behaviours ceased within a mean ± SD of 13–58 days (23.30 ± 14.17) after implantation. DHT concentration decreased within 30 days. The mean duration of suppression was 26.5 ± 7.42 months and reactivation coincided with increased DHT values reaching preimplantation concentrations within 1 month. 17β-oestradiol concentrations significantly correlated with DHT concentrations ( P <0.01). For cats castrated during suppression of sexual behaviour, the length of the long axes of the nuclei of Leydig cells, the diameter of seminiferous tubules and the height of the epithelium of the seminiferous tubules did not change until 3–6 months after implantation, whereas at 12 and 32 months the measured values were even lower than in the control group. For cats castrasted after reactivation, the length of long axes of the nuclei of Leydig cells and the diameter of seminiferous tubules approached the values of the control group between 4 and 6 months after reactivation. Conclusions and relevance A deslorelin implant (4.7 mg) suppresses sexually dimorphic behaviour in tom cats without any side effects and with full reversibility; however, duration of suppression is highly individual.

Background: This study was designed to investigate the effect of tranexamic acid and its side effects in preventing postpartum hemorrhage in patients referred to Ali ibn Abitaleb Hospital in Zahedan during 2020-2021. Methods: Patients were divided into two groups of 85 patients. Vital signs as well as drug side effects related to tranexamicity are monitored and recorded every15 minutes in the first hour and every 30 minutes in the second hour. Also, blood samples are taken from patients to measure hemoglobin and hematocrit within6 hours after delivery. The number and weight difference of droschitis used during 2 hours after delivery are also measured. In addition, PPH (Postpartum hemorrhage) cases in both groups were checked by repeated examination of the uterine fundus during the first 2 hours and after 6 weeks. Results: There was no statistically significant difference between the two groups in terms of the number of deliveries and further decrease in hemoglobin levels in the control group compared to the intervention group. Nausea, vomiting, and dizziness were observed in the intervention group and thrombosis was not observed in any group. According to the independent samples t-test, there was a statistically significant difference between the mean blood volume lost between the two groups. The mean hematocrit drop was statistically significant between the two groups. No blood transfusion was observed in any of the patients. Conclusion: Tranxamic acid injections can effectively reduce postpartum hemorrhage and reduce maternal hemoglobin and hematocrit following this complication.

The insectivorous bat Myotis nigricans is widely distributed throughout the Neotropics, including Brazil, and has a reproductive biology that is affected by climate and food availability. To evaluate the reproductive capacity of this species, morphofunctional parameters of the testes were correlated with environmental variables and the body condition of individuals captured. After bats had been killed, their testes were removed, fixed in Karnovsky’s fluid for 24 h and embedded in resin for evaluation by light microscopy. The mean annual tubulosomatic index (0.58%) and the percentage of seminiferous tubules in the testes (88.96%) were the highest ever recorded for the Order Chiroptera. The percentage of Leydig cells and volume of the cytoplasm of Leydig cells were higher in the rainy than dry season (80.62 ± 3.19% and 573.57 ± 166.95 μm, respectively; mean ± s.d.). Conversely, the percentage of nuclei of the Leydig cells in the dry season (26.17 ± 3.70%; mean ± s.d.) and the total number of Leydig cells (6.38 ± 1.84 × 109; mean ± s.d.) were higher in the dry season. The results of the present study could help in future conservation of these bats because they provide a better understanding of the bats’ reproductive strategies and how the species can adapt to changes.

Background: Dexamethasone (DEX) is a common medicine that is capable of causing malformation in the male reproductive system. The aim of this study was to investigate the effect of vitamin C (Vit-C) on spermatogenesis indexes and daily sperm production (DSP) in adult mice treated with DEX. Methods: Male Naval Medical Research Institute (NMRI) mice were divided into four groups: Control, DEX (7 mg/kg/day), Vit-C (100 mg/kg/day), and DEX +Vit-C and treated for 7 days with intraperitoneal injection. Results: A significant increase in the mean levels of serum and tissue malondialdehyde (MDA) and apoptosis of Leydig cells was found in the DEX group compared to the control group. Sperm motility, DSP, tubular differentiation index, meiotic index, spermatogenesis index, the mean number of spermatocytes, round and long spermatids, and Leydig cells, and also serum testosterone level decreased in the DEX group compared to the control group. The results of this study indicate that Vit-C can significantly prevent the adverse effects of DEX on the mean number of spermatocyte, spermatid, and Leydig cells, tubular differentiation, meiotic and spermatogenesis index, DSP, sperm motility, and the mean levels of serum MDA. Conclusion: In conclusion, our results showed that coadministration of Vit-C and DEX prevents the adverse effects of DEX on the spermatogenesis indexes and DSP.

Background: Infertility is a major cause of marital disharmony in Nigeria because of the high premium placed on childbearing. Unfortunately, the blame is on the woman most times in Nigeria. Seminiferous tubules comprise 80-90% of testicular mass. Thus, the testicular volume is an index of spermatogenesis. Therefore, accurate testicular volume will help in assessing testicular function if there is no obstruction. This study was conducted to evaluate the correlation between testicular volume, measured by ultrasound and conventional sperm parameters (semen volume, sperm concentration, sperm motility and sperm morphology) in men with infertility presenting to Urology Division, University of Abuja Teaching Hospital, Gwagwalada Abuja. Methodology: This was a descriptive cross sectional study, male subjects with infertility presenting to University of Abuja Teaching Hospital were recruited into the study. The testicular volume of all the subjects was measured by ultrasonography. The semen samples were collected by the process of masturbation on day five of sexual abstinence and analyzed according to WHO criteria 2010. Collated data were analyzed using SPSS version 20.0. P-value<0.05 was taken as statistically significant. Results: The average total testicular volume (TTV) of men with infertility was 19.83 ml while mean testicular volume (MTV) was 10.24 ml. There was a statistically significant difference between MTV and semen volume (r=0.391, p=0.000), and sperm concentration (r=0.639, p=0.000). There was a weak and insignificant correlation between MTV and sperm motility and MTV and morphology (r=0.216, p=0.055 and r=0.076, p=0.502) respectively. Linear regression analysis showed significant impact of MTV (P<0.001) on sperm concentration with a critical MTV of ≤10ml.0 indicating poor testicular function (severe oligospermia) Conclusion: The mean ultrasonic testicular volume in men with infertility in this study was 10.24ml and there was a significant positive correlation of MTV with semen volume and sperm concentration. Although, there was correlation of MTV with sperm motility and morphology, this was not significant. The critical mean ultrasonic testicular volume indicating poor testicular function (severe oligospermia) was found to be 10ml. This study has shown that the mean ultrasonic testicular volume can be a pointer to semen volume and sperm concentration in evaluating men with infertility.

The Impact

The objective of this study was to determine the effects of wood, cigarette and marijuana smoke on the reproductive health of tandoor occupants. A total of 100 male individuals were selected (50 control and 50 tandoor occupants). A standard questionnaire was designed regarding their age, economic status, marital status, fuel type, exposure time (per day), use of mask, addiction and reproductive health. Morning blood samples of 5 mL of the size were taken from all participants. Serums were obtained and analyzed for total serum testosterone concentration. Bio-check (USA) kit was used according to the manufacturer protocol and procedures for testosterone analysis. In control group the mean ± SEM of total serum testosterone was 671.9 ± 20.02 ng/dl where as in tandoor occupants it was 542.7 ± 16.40 ng/dl. There was a significant reduction (P**** < 0.0001) in total serum testosterone concentration in tandoor occupants as compared to control group. Reproductive health problems like, low libido, erection problems, infertility, decreased frequency for shaving and absent morning and nocturnal erection were common in tandoor occupants as compared to control group. Wood, cigarette and marijuana smoke negatively affects testosterone concentration and lowers it significantly. This reduced testosterone concentration then produces ill effects like low libido, erection problems, infertility and absent morning and nocturnal erection.

Neuronal Systems

The nerve growth factor (NGF) not only has an essential effect on the nervous system, but also plays an important role in a variety of non-neuronal systems, such as the reproductive system. The aim of this study was to investigate the seasonal changes in<strong> </strong>expression of NGF and its receptors (TrkA and p75) in testes of the wild ground squirrel during the breeding and nonbreeding seasons.<strong> </strong>Immunolocalization for NGF was detected mainly in Leydig cells and Sertoli cells in testes of the breeding and nonbreeding seasons. The immunoreactivity of TrkA was highest in the elongated spermatids, whereas p75 in spermatogonia and spermatocytes in testes of the breeding season. In the nonbreeding season testes, TrkA showed positive immunostainings in Leydig cells, spermatogonia and primary spermatocytes, while p75 showed positive signals in spermatogonia and primary spermatocytes. Consistent with the immunohistochemical results, the mean mRNA and protein level of NGF and TrkA were higher in the testes of the breeding season, and then decreased to a relatively low level in the nonbreeding season. In addition, the concentration of plasma gonadotropins and testosterone were assayed by radioimmunoassay (RIA), and the results showed a significant seasonal change between the breeding and nonbreeding seasons. To conclude, these results of this study provide the first evidence on the potential involvement of NGF and its receptor, TrkA and p75 in the seasonal spermatogenesis and testicular function change of the wild ground squirrel.

Methoxychlor (MXC) is an insecticide (DDT derivates) that has the potential for bioaccumulation in mammal and causes a disruptive effect on the hepar and reproductive system. This study was done to find out the benefits of curcumin as a natural ingredient to overcome the negative impact of Methoxychlor (MXC) on hepar and male reproductive organ of Balb’C mice (Mus musculus L). The study was carried out in a Completely Randomized Design (CRD) Posttest Only Control Group Design used four treatments and six replications. The curcumin treatment after administration of MXC was carried out by gavage with curcumin doses: 0.05; 0,1; and 0.2 mg/g body weight, every day for two weeks, respectively. Histological observations of the liver, and testis was performed using the paraffin method and Hematoxylin Eosin stained. The results showed that MXC exposure caused liver disruption by increasing the number of pycnotic necrotic hepatocytes and hydrophic degeneration hepatocytes. On the male reproductive organ, MXC caused testis impairment by reducing the number of Sertoli cells and Leydig cells, spermatogenic cell counts, and the diameter of seminiferous tubules. The administration of curcumin at doses of 0.1 mg/g bw in mice exposed to methoxychlor can reduce the number of hydrophic degeneration hepatocytes and tend to reduce the number of pycnotic hepatocytes; and also increase the number of Sertoli cells, the number of spermatogenic cells, and the diameter of the seminiferous tubules, and tend to reduce the amount of Leydig cells. Curcumin treatment tends to recover hepar dan testis disruption of mice that were exposed by MXC.

AbstractObjectives:  The objective of this research work was to observe the testicular morphological changes produced by fluoroquinolones in the reproductive organs of adult male albino rats, and to see whether these changes are reversible after discontinuation of the drugs.Materials and Method:  Eighty adult male albino rats weighing 200 – 300 gms were randomly selected and divided into four groups i.e. A, B, C & D, having 20 animals in each group. A, B & C, were the experimental groups & D served as control group. All the groups were further divided into sub groups 1 & 2. Three fluoroquinolones i.e. Ciprofloxacin (135 mg / kg / day), Ofloxacin (75 mg / kg / day) & Enoxacin (12.5 mg / kg/ day) were given to the groups A, B & C respectively for 42 days. Animals of group D received dis-tilled water only. Animals of sub groups A1, B1, C1 &D1 were sacrificed on 42nd day and testicular tissue was obtained for morphological study. Animals of subgroups A2, B2, C2 & D2 were sacrificed on 84th day and testicular tissue for morphological changes was taken. No of leydig cells, height of epithelium and diameter of seminiferous tubules were taken as experimental parameters for morphological changes.Results:  The study indicated statistically significant (P < 0.05) decrease in height of epithelium, diameter of seminiferous tubules and no. of leydig cells in experimental groups as compared to the control groups.Conclusion:  The changes observed in morphology could lead to decrease in sperm count and testosterone levels. This study suggests gonadotoxic potentials of fluoroquinolones and adds concern to the indiscriminate and widespread use of fluoroquinolones and recommends more rational use of these drugs.

This study aims to determine the effect of red dragon (Hylocereus polyrhizus) fruit peel extract (RDFPE) on the parameters of Leydig cells number, seminiferous tubules diameter, and testicular weight of mice (Mus musculus) exposed to heat (40°C). Twenty adult male mice were divided randomly into five groups. The control group (C) mice only received a placebo. Meanwhile, the treatment groups mice were exposed to heat for 45 minutes daily for 36 days and oral administration of placebo, RDFPE of 250, 500, and 1000mg/kg BW for T0, T1, T2, and T3, respectively. The result showed that heat exposure on mice (T0 group) caused a lower of all of the parameters (p <0.05) than normal mice (control group, C). RDFPE administration at a dose of 250 mg/kg BW (T1 group) and 500 mg/kg BW (T2 group) resulted in a higher value of those parameters (p <0.05) compared to the T0 group. All those parameters of the T2 group (dose of 500 mg/kg BW) were not significantly different (p >0.05) than the control group (normal mice). However, the higher dose of RDFPE (1000 mg/kg BW, T3 group) resulted in the lower values of those parameters (p <0.05) than those of the T2 group. It could be concluded that 500mg/kg BW dose of RDFPE could return Leydig cells number, seminiferous tubules diameter, and testicular weight of mice (Mus musculus) exposed to heat.

The present study was aimed to investigate the possible effects caused by the antibiotic, metronidazole, on the histology of the testis and the morphology of the sperms of mice. To achieve this,  adult male albino Swiss Mice were orally administrated with 0.1 ml (100 mg\ kg ) of the commercially used metronidazole (Flagyl) for 60 consecutive days. The results showed significant decreases (p<0.05) in the mean weight of body and testis in the treated mice as compared to the distilled water-treated control group. The treatment also caused several histopathological changes in the testis which included necrosis, congestion, hemorrhage, edema, germ cell downfall  and rupture in the seminiferous tubules. The tests of the sperm morphology revealed a number of deformations as a result of the treatment, such as the appearance of headless,  bend, broken-tailed, hook-tailed, and two-headed sperms, as well as sperms with cytoplasmic droplets. We conclude that from these results that orally administered Metronidazole exerts negative effects on the male reproductive system of mice .
