RESUMO
Rosemary (Rosmarinus officinalis L.) is a shrub used to treat hepatic, intestinal, renal, respiratory, and reproductive failures. Etoposide a plant-based compound derived from Podophyllum pelltatum, has been used for human malignancies treatment. However, it induces testis, and hepatic failures. In the present study, impact of rosemary essential oil against testis failure, lipid parameters, and hepatic enzymes in male rats has been studied. Forty male Wistar albino rats were grouped in a completely randomized design with Etoposide injection (ETO), rosemary supplementation (ROS), with Etoposide injection and rosemary supplement (ETO+ROS), and control rats with no Etoposide injection and no rosemary (CON). The experiment lasted for seven consecutive weeks including one week as acclimatization time. At the end of the experiment, rats were sacrificed by cervical dislocation, and blood samples were analyzed for serum alkaline phosphatase (ALP), alanine aminotransferase (ALT), aspartate aminotransferase (AST), triglyceride (TG), low-density lipoprotein-Cholesterol (LDL-C), high-density lipoprotein-cholesterol (HDL-C), total cholesterol (TC), total Protein (TP), glucose (GLU) and testosterone. The left testis was harvested for histological examination. Results showed that rats with Etoposide injection had higher ALT, AST, and ALP the control rats. No significant difference was found among treatments in terms of glucose concentration in blood. Rosemary supplemntaion decreased cholesterol and TG concentration and increased HDL concentration in male rats. Furthermore, administration of rosemary essential oil increased blood testosterone but decreased ALT and AST. The epithelial height of seminiferous tubules was decreased significantly in ET as compared with CON. Rosemary essential oil lessened the adverse effect of Etopside on epithelial height in rat testis as it is shown in ET+ROS. In conclusion, dietary supplementation of rosemary essential oil alleviated liver toxicity and functional testis damage induced by Etopside.

Scrotal calcinosis is a rare disorder characterized by multiple papules or nodules of calcification in the scrotal skin. The pathogenesis of this disease is poorly understood. The condition presents as several brown to yellowish asymptomatic nodules on the scrotum. Excision followed by scrotal reconstruction is the treatment of choice. It leaves a good cosmetic result with low chances of recurrence. Newer treatments, such as ablative lasers, have been proposed with very good results. We describe the case of a 28-year-old patient with a history of severe acne treated with oral isotretinoin that presented for scrotal nodules. On laboratory examination, hypercalcemia was found with normal phosphorus, parathyroid hormone, and vitamin D hormone levels. Hypercalcemia was linked to his isotretinoin therapy. Serum calcium concentrations normalized after cessation of isotretinoin and hydration. Because the patient refused surgery, a biopsy of the lesion confirmed the diagnosis of scrotal calcinosis. Then the patient was referred to a cosmetic laser center to treat his condition.

Cyclophosphamide (CP) is commonly used as antineoplastic and immunosuppressant drug with noticeable gonadotoxic profile. Nerolidol (NER) is a sesquiterpene with potent antioxidant and anti-inflammatory properties. Thus, the present study was designed to explore its possible gonadal protective potential against cyclophosphamide-induced testicular, epididymal, seminal and spermatozoal toxicities. Animals were divided into five groups: control (normal saline for 14 days), treatment group (NER 200 and 400 mg/kg, p.o) for 14 days along with a single dose of cyclophosphamide (200 mg/kg, i.p) on 7th day, toxic and Per se groups (cyclophosphamide 200 mg/kg i.p) on 7th day and NER 400 mg/kg for 14 days respectively. Animals were sacrificed on the 15 day, and body weight, weight of reproductive organs, testosterone level, sperm count, biochemical parameters, histopathological and immunohistochemical studies were performed in the testes, epididymis and in the serum. CP administration induced oxidative stress, nitrative stress, inflammation, reduced testosterone level, sperm count, increased expression of MPO and caused histological aberrations in the testes, epididymis and seminal vesicles. CP caused reduced sperm count, sperm motility and testosterone level which got reversed upon treatment with nerolidol in a dose-dependent manner. Nerolidol thus acted as a gonadoprotective molecule and prevented the gonadotoxicity of CP.

This study aimed to investigate the effect of pentoxifylline on complications of prolonged usage of morphine upon the testis and sperm parameters of rats. In this study, forty male Wistar rats were divided into five groups (n = 8) and treated for 56 days to only saline, only morphine, only pentoxifylline, pentoxifylline + morphine and naltrexone + morphine. The diameters of seminiferous tubules, the maturity of germ line epithelium and sperm parameters were evaluated. The expression of inflammatory-related factors in testis tissues were also investigated at gene and protein levels. The data were calculated by one-way ANOVA test followed by Tukey's post hoc test using SPSS software for windows (version 20). Seminiferous tubule diameter, the maturity of spermatogonia and sperm parameters were significantly decreased in morphine group in comparison with control, pentoxifylline and pentoxifylline + morphine groups (p < .001). The expression of anti-inflammatory markers, at both gene and protein levels, was significantly increased in testis of morphine-treated rats in comparison with other groups (p < .001). Chronic morphine administration induces destructive effects on male reproductive system by regulating inflammatory responses. Pentoxifylline recovers the destructive effects of morphine on male reproductive system by inhibiting TLR (Toll-like receptor) activity, as an anti-inflammatory response.

This is an attempt to establish the normal stretched penile length and prevalence of male genital anomalies in full-term neonates and whether they are influenced by prenatal parental exposure to endocrine-disrupting chemicals. A thousand newborns were included; their mothers were subjected to the following questionnaire: parents' age, residence, occupation, contact with insecticides and pesticides, antenatal exposure to cigarette smoke or drugs, family history of genital anomalies, phytoestrogens intake and history of in vitro fertilization or infertility. Free testosterone was measured in 150 neonates in the first day of life. Mean penile length was 3.4±0.37 cm. A penile length <2.5 cm was considered micropenis. Prevalence of genital anomalies was 1.8% (hypospadias 83.33%). There was a higher rate of anomalies in those exposed to endocrine disruptors (EDs; 7.4%) than in the non-exposed (1.2%; p<0.0001; odds ratio 6, 95% confidence interval 2-16). Mean penile length showed a linear relationship with free testosterone and was lower in neonates exposed to EDs.

In the last decade interest has increased in the possible effects of endocrine disruptor compounds. Numerous papers have appeared as to their possible effects on humans, but definitive effects are hard to demonstrate. In the field of animal husbandry, however, the effects of the endocrine disruptors are well documented. This paper discussed the effects of the endocrine disruptors seen in animals and the possible implications for humans. The areas considered are reproductive disorders, premature udder/breast development, prolapsed oviduct/uterus, scrotal atrophy, and skewed sex ratio.

Boric acid (H3BO3), an inorganic acid with widespread commercial use and consumer exposure, impairs fertility in male rodents at dose levels lower than those required to cause other adverse effects. Previous studies found a testicular lesion in adult Fischer rats fed 9000 ppm boric acid (1575 ppm boron) and slightly reduced basal serum testosterone levels. A CNS-mediated hormonal component to this lesion was suggested. Detailed data on the tissue disposition of boron in the rat, including accessory sex organs and the brain, are lacking. This study examined the tissue disposition of boron in reproductive, accessory sex organs, and other selected tissues in adult male Fischer rats fed 9000 ppm boric acid to determine if selective accumulation of boron in reproductive tissues, accessory sex organs, and/or the brain might correlate with and explain the apparent selective testicular toxicity. Adult male Fischer rats were fed 9000 ppm boric acid for up to 7 days. Animals were killed at 1, 2, 3, 4, and 7 days after the start of exposure. Plasma and excised tissues were heat-digested in acid and analyzed for boron by inductively coupled argon plasma emission spectrometry (ICAP). With the exception of adrenal glands, control boron levels in all tissues examined were below 4 micrograms/g. There was a rapid increase in plasma and tissue boron 1 day after the start of exposure (range 2- to 20-fold), with the exception of adipose tissue. With the exception of bone and adipose tissue, all soft tissues examined, including the testis, epididymis, accessory sex organs, hypothalamus, and rest of brain, appeared to reach steady-state boron levels (range 12-30 micrograms/g) by 3-4 days. Bone boron levels continued to increase up to the termination at 7 days (40-50 micrograms/g by Day 7). Bone attained the greatest concentration of boron (2- to 3-fold over plasma levels) while levels in adipose tissue were 20% of plasma levels during the 7-day exposure period. All other tissues appeared to show no appreciable accumulation of boron over plasma levels. The data suggest that neither the apparent selective testicular toxicity nor the slight CNS hormonal effect associated with boric acid exposure can be explained on the basis of selective accumulation of boron in the testis or brain/hypothalamus, respectively. Thus, the testicular toxicity is likely the result of certain biological processes that are unique to the testis and which are targets of boron exposure.

Ethanolic extracts of the aerial parts of Artemisia abyssinica and A. inculta were subjected to acute toxicity observations in mice for 24 h and chronic toxicity evaluation for 3 months. External morphological changes, visceral toxicity, haematological changes, spermatogenic dysfunction and effect on body weight and vital organ weight were recorded. In both the chronically treated groups, no significant acute mortality was observed up to 3 g/kg p.o. There was no weight gain in A. abyssinica chronically-treated mice while the weight gain of A. inculta-treated animals matched that of the control group. Significant sperm damage was observed in A. abyssinica-treated mice while A. inculta failed to produce any significant spermatotoxic effect.
