Detrimental Effects of Saccharum officinarum Juice on Reproductive Functions of Female Wistar Rats.

Changing dietary compositions have contributed to the growing epidemic of metabolic diseases with serious impacts on several aspects of health, including reproductive health.  Saccharum officinarum juice has a natural sweetness that makes the general populace relinquish its use as a sweet course and well-known raw material for the production of refined sugar. Studies have reported adverse effects of this juice on male reproductive functions, but there is a paucity of information on females. This study investigated the effects of fresh Saccharum officinarum juice on the reproductive functions of female Wistar rats. A sugarcane press juicer was used to extract Saccharum officinarum juice. Twenty female Wistar rats (180-200 g) grouped into four (n = 5) received 1.0 mL/kg/day distilled water (control), and 1.0, 3.2, and 10.0 mL/kg/day of fresh Saccharum officinarum juice once daily for 21 days by gavage. Serum follicle-stimulating hormone, luteinizing hormone, and estrogen levels were measured using enzyme-linked immunosorbent assay (ELIZA). The estrous cycle was assessed using the Marcondes principle and histology of the ovary and uterus were assessed by microscopy. Data were analyzed using the Analysis of variance at a significance of p < 0.05. Saccharum officinarum juice caused an increase in the body weight and serum levels of follicle-stimulating hormone and luteinizing hormone. It altered the estrous cycle by increasing the frequency of occurrence of the proestrus phase but reduced that of the metestrus phase. The juice altered the cytoarchitecture of the ovaries via vacuolations and cysts within the ovarian stroma, while the uterine section showed distorted endometrial lining and glands. Saccharum officinarum juice inflamed the ovaries and distorted the estrous cycle and uterine endometrial lining. Saccharum officinarum juice consumption may possess deleterious effects on the reproductive functions of female Wistar rats.   Keywords: Saccharum officinarum juice, Ovary, Uterus, Estrous cycle, Infertility.

Therapeutic efficacy of N-acetylcysteine and zinc sulphate against di-(2-ethylhexyl) phthalate-induced testicular oxido-nitrergic stress in male Wistar rat.

The therapeutic efficacy of N-acetylcysteine (NAC) and zinc sulphate on di-(2-ethylhexyl) phthalate (DEHP)-induced testicular oxido-nitrergic stress in rats was investigated in 36 male Wistar rats (170 ± 10 g) randomly assigned into one of six groups (n = 6). Group 1 (control) received 2.5 ml/kg of distilled water for 42 days, while group 2 (vehicle) received 2.5 ml/kg of corn oil for 42 days. Groups 3,4,5, and 6 were administered DEHP (750 mg/kg/day) for 21 days, after which groups 4, 5, and 6 received zinc sulphate (0.5 mg/kg/day), NAC (100 mg/kg/day), and zinc sulphate (0.5 mg/kg/day) + NAC (100 mg/kg/day) for an additional 21 days respectively. After the experimental period, the animals were euthanized by light thiopental sodium, and their testes were carefully dissected out for histological and biochemical assays. The result shows a significant alteration in testicular levels of malondialdehyde, nitric oxide, antioxidant enzymes, total antioxidant capacity, sulphydryl levels, dehydrogenases and testicular architecture following the administration of DEHP. These effects were reversed by coadministration of NAC and zinc sulphate in the study. We therefore concluded that the combined effects of NAC and ZnSO4 effectively improved testicular antioxidant status and reduced testicular nitregic stress, thus improving testicular architecture and functions.

Reproductive effects of Abelmoschus esculentus fruit methanol extract in female Wistar rats.

Current researches aim at identifying modifiable risk factors for infertility, particularly dietary lifestyle. Abelmoschus esculentus is one of the important vegetables in the human diet with reported valuable nutrients but has been linked with reproductive dysfunction in males. This study investigated the reproductive effects of Abelmoschus esculentus fruit methanol extract in female Wistar rats. Dried Abelmoschus esculentus fruit was extracted with methanol. Fifteen female Wistar rats (180-200 g) grouped into three (n = 5) received 1.0 mL/kg/day distilled water (control), 70 and 200 mg/kg/day of the extract once daily for 21 days via oral gavage. The estrous cycle was assessed using Marcondes and Papanicolaou methods. The histology of the tissues was evaluated by microscopy. Serum follicle-stimulating hormone, luteinizing hormone, and estrogen levels were measured using an enzyme-linked immunosorbent assay. Tissue antioxidant activities and malondialdehyde levels were assayed by spectrophotometry. Data were analyzed using the Analysis of variance at a significance of p < 0.05. The estrous cycle of the Abelmoschus esculentus fruit methanol extracts treated rats showed normal cellular characteristics. Though Abelmoschus esculentus fruit methanol extract increased the antioxidant activities, it reduced the body weight and follicle-stimulating hormone level and caused severe inflammation and fibrosis of the ovary and uterus. Abelmoschus esculentus fruit methanol extract adversely altered the reproductive functions of female Wistar rats by disrupting the ovarian and uterine cytology and reducing hormone levels.

Saccharum officinarum juice alters reproductive functions in male Wistar rats.

Infertility is a problem across almost all cultures and societies. Problems in the male partner, especially as a result of unhealthy dietary habits, are the commonest single group of course. Many populations, therefore, tend more toward the use of natural dietary substitutes opined to proffer less risk to reproductive functions and more health benefits. Saccharum officinarum juice (SOJ) is a widely consumed, energy-rich, nutritious substance that has many minerals and enzymes. Saccharum officinarum plant was reported to have anti-thrombosis, anti-inflammatory and immune-stimulatory activities. This study evaluated the reproductive effects of S. officinarum juice in male Wistar rats. A sugarcane press juicer was used to extract S. officinarum juice. Twenty male Wistar rats (100-120 g) grouped into four (n = 5) received 1.0 mL/kg/day distilled water (control), and 1.0, 3.2 and 10.0 mL/kg/day of fresh S. officinarum juice once daily for 8 weeks via gavage. Sperm analysis, histology of testes and epididymides were evaluated by microscopy. Enzyme-linked immunosorbent assay (ELISA) was used in assessing the serum levels of luteinizing hormone, follicle-stimulating hormone and testosterone. Data were analyzed using the analysis of variance at a significance of p < 0.05. SOJ increased fasting blood glucose levels in 3.2 and 10.0 mL/kg groups. The 10.0 mL/kg juice caused a significant increase in testosterone level and sperm count, and it also increased the percentage of aberrant sperm and decreased sperm viability. Saccharum officinarum juice impaired the histological integrity of the testes and epididymides. Thus, S. officinarum juice adversely altered the reproductive functions of male Wistar rats by reducing sperm quality and disrupting testicular architecture.

Saccharum officinarum molasses adversely alters reproductive functions in male wistar rats.

The widely reported anti-androgenic effects of refined sugar led to the exploration of safer alternatives. Saccharum officinarum molasses (SOM), a byproduct of sugar processing is gaining popularity as a substitute. This study investigated the effects of SOM and compared them to those of refined sugar on male reproductive functions. Blackstrap® Saccharum officinarum molasses were subjected to phytochemical screening and proximate analysis and fractionated to obtain methanol (SOMMF) and aqueous (SOMAqF) fractions. Twelve groups (n = 5) of adult male Wistar rats received distilled water (Control); 0.8, 2.5, 7.9 g/kg SOM; 0.0064 g/kg sugar (Dangote®); 0.0064 g/kg sugar+7.9 g/kg SOM; 1.0, 3.2, 10.0 g/kg SOMMF and 0.6, 2.0, 6.4 g/kg SOMAqF, respectively. Administrations were done daily by oral gavage for eight weeks. Sperm profile and testicular and epididymal histology were assessed using microscopy. Serum testosterone was quantified using ELISA. Testicular malondialdehyde (MDA) was assayed by spectrophotometry. Data were analyzed using ANOVA at p < 0.05 significance. Sperm count and viability reduced with 7.9 g/kg SOM, Sugar, 3.2 and 10.0 g/kg SOMMF, 2.0 and 6.4 g/kg SOMAqF. Abnormal sperms increased with 7.9 g/kg SOM, Sugar, 2.0 and 6.4 g/kg SOMAqF. Testosterone level reduced with 6.4 g/kg SOMAqF. Testicular MDA increased with SOM, 3.2 and 10.0 g/kg SOMMF and 6.4 g/kg SOMAqF. Seminiferous tubules and epididymal ducts of 7.9 g/kg SOM, Sugar and SOMAqF-treated rats showed anomalies. Saccharum officinarum molasses altered testicular and epididymal integrity via lipid peroxidation, thus reducing sperm quality and androgen levels in male Wistar rats.

The effect of Chrysophyllum albidum fruit on testicular functions in rats.

The prevalence of male infertility is a well-known public health issue with majority of cases due to deficient sperm production of unknown origin. Studies have associated dietary habits with male factor infertility. Chrysophyllum albidum is a common plant that produces a popular fruit, widely consumed for its nutritional and medicinal values. This study investigates the effects of C. albidum fruit methanol extract on the reproductive functions of male Wistar rats. Ripe C. albidum fruit was extracted using methanol and subjected to phytochemical screening. Fifteen male Wistar rats (100-120 g) divided into three (n = 5) received distilled water (control), 1.0 and 6.4 g kg-1  day-1 extract, respectively, for 28 days via oral gavage. The sperm count, motility, percentage sperm aberration, histology of testes and epididymides were examined by microscopy. Serum levels of luteinising hormone (LH), follicle-stimulating hormone (FSH) and testosterone were quantified using ELISA. Data were analysed using ANOVA at p < 0.05 significance. Sperm count significantly increased in 6.4 g kg-1  day-1 extract. Serum testosterone level decreased in 1.0 and 6.4 g kg-1  day-1 extract. The architecture of sections of testes and epididymides showed anomalies. C. albidum fruit adversely altered reproductive functions of male Wistar rat.

Implication of caffeine consumption and recovery on the reproductive functions of adult male Wistar rats.

BACKGROUND: This study assessed the impact of caffeine consumption and recovery on reproductive functions and fertility of Wistar rats. METHODS: Thirty-five adult male Wistar rats were divided into seven groups of five rats each. Group A (control) received distilled water (vehicle), while groups B, C, and D were treated orally with 10 mg/kg body weight (BW), 20 mg/kg BW, and 40 mg/kg BW caffeine, respectively, for 30 days. Groups E, F, and G were treated orally with 10 mg/kg BW, 20 mg/kg BW, and 40 mg/kg BW caffeine, respectively, for 30 days and then allowed to recover for another 30 days. RESULTS: Caffeine caused a decrease in body weight, while recovery groups showed appreciable increase in body weight during recovery. Relative weight of seminal vesicle, prostate, and epididymis decreased dose dependently during treatment but increased during recovery. The liver and kidney weight increased during treatment but reduced during recovery. Sperm count was significantly decreased in both treated and recovery groups. Initial decrease in sperm viability and volume was appreciably reversed during recovery period. Serum level of testosterone increased at high doses, while serum luteinizing hormone (LH) and follicle-stimulating hormone (FSH) showed significant decrease. Histological sections of testis in treated groups showed mild congestion of the interstitial blood vessel and subcapsular congestion. However, there was no subcapsular congestion in the recovery groups. All rats in both treated and recovery groups had 100% fertilization success from fertility study. CONCLUSIONS: Suggestively, caffeine treatment for 4 weeks could impair body, reproductive organs weight, sperm characteristics, LH/FSH level, and also testicular cyto-architecture. Effects appeared, however, reversible after caffeine withdrawal.

Effects of Oral Maternal Administration of Caffeine on Reproductive Functions of Male Offspring of Wistar Rats.

Caffeine was investigated for its possible fetal programming effects on reproductive function of male offspring. Sixty-five pregnant Wistar rats were grouped into four. Group 1 was control and received distilled water. Groups 2, 3 and 4 were treated orally with 1.14, 3.42 and 5.70 mg/kg body weight of caffeine respectively. Each group was subdivided into four based on gestation days (GD) 1-7, 8-14, 15-21 and 1-21. The day of parturition was taken as postnatal day zero (0). Male offspring were sacrificed on postnatal day 70. Parameters determined were: weight at birth, body weight at postnatal day 21 and 70, anogenital distance (AGD) index, sperm parameters, reproductive organ weight, histology and hormonal profile (testosterone, FSH and LH). Data were analyzed using Analysis of Variance. Level of significance was taken at P<0.05. Male offspring belonging to caffeine treated dams showed dose dependent significant decreases in birth weight. Male offspring from dams treated with caffeine during GD 1-7 and GD 1-21 had a significant increase in their AGD index. Also, male offspring from dams treated with 1.14 and 5.70 mg/kg body weight of caffeine during GD 8-14 had a significant increase in AGD index. Dams treated with 3.42 mg/kg body weight of caffeine during GD 15-21, had a significant increase in the AGD index of their male offspring. The sperm motility of offspring from dams treated with 5.70 mg/kg body weight of caffeine during GD 1-7 and GD 1-21 were significantly increased. Offspring of GD 8-14 and GD 15-21 dams treated with 3.42 and 5.70 mg/kg body weight of caffeine respectively, showed significantly reduced serum testosterone level. There was a significant decrease in the weight of testes of offspring from dams treated with caffeine during GD 8-14. Histological sections of testes of offspring from caffeine treated dams showed interstitial congestions, edema, reduced germinal epithelial height and detached basal membrane. Maternal caffeine exposure during different gestational periods adversely affected birth weight and some reproductive indices in male offspring of Wistar rats.
