Abstract:

Testicular maturation was assessed in age-matched, sexually immature (13–17-week-old) New Zealand white rabbits using end points frequently evaluated in toxicity studies: testicular weight and testicular histology. Testicular weights and testicular maturity as assessed histologically were markedly variable in sexually immature rabbits, especially at ≥ 14 weeks of age. The large variation in testicular weights in immature rabbits requires that large changes in a treatment group relative to controls be present for statistical detection of testicular weight effects at commonly used significance l

Abstract:

Background: Monosodium glutamate (MSG), a common food additive, has been linked to hormonal imbalances and reproductive toxicity. This study examines its effects on body weight, organ weight, testicular structure, and hormone levels in albino rats. Methods: The rats were categorized into a control group and an MSG-treated group. Body weight, testis weight, and serum testosterone levels were measured, and testicular tissue was analyzed histologically. Results: MSG-treated rats showed reduced weight gain, lower testis weights, and decreased testosterone levels. Histological analysis revealed str

A MODIFIED approach in testicular biometry in boars is described. Twelve mature Large White pigs were used for this study. Half the major axis of the testis (a) and the square of half the minor axis [b2] were highly significantly correlated with both testicular weight and testicular volume. The multiple correlations between a and b2 and the testis weight and testis volume were respectively 0.94 and 0.96 and equally highly significant.  The testicular weights and volumes calculated with the multiple regression equations obtained in this study accounted for 99% and 97% of the actual values

The hypothalamic-pituitary-gonadal axis (HPG) controls the reproductive physiology activities of stallions. The organs involved in this axis are the hypothalamus, the pituitary, and the gonads (testes), and the endocrine secretions from these organs. This study determined the correlation between testicular measurements and reproductive hormones of cross Arewa stallion in Ilorin. Forty-three crossed Arewa breeds of stallions were sampled. Testicular measurements (left and right testicular width, length, height, total testicular volume, and total testicular weight) were taken for each sample. Se

A study was conducted to investigate the effect of season on testicular morphometric parameters and sperm production in adult Guinea cocks. Five (5) Guinea cocks (GCs) were randomly selected from a group of thirty homogenous adult pearl Guinea cocks during the major rainy, minor rainy season, and dry seasons of the year. The selected GCs were humanely euthanized and used for determining testicular morphometric parameters, sperm reserve, and sperm production. The results of this study showed that the body weight of Guinea cocks (GCs) and testicular morphometric parameters were significantly (P&

Abstract:

Background: Testicular toxicity following chemotherapy is of increasing importance with the continuous improvement of survival rates. Gonadotropin-releasing hormone (GnRH) was suggested to protect testis against such toxicity; however, its suppressive quality and mechanism of action are still unclear. We examined whether and how pretreatment with GnRH antagonist protects against the testicular damage caused by chemotherapy. Methods: Mature male mice were injected subcutaneously eight times in 2-day intervals with either saline or GnRH antagonist (Cetrotide; 1 g/mg), followed by an intraperiton

Abstract:

Cyclophosphamide (CP)—which is used to treat autoimmune diseases and cancer—is related to gonadotoxicity attributed to oxidative stress. As phycobiliproteins (PBPs) are strong antioxidants that are unexplored as protective agents against male gonadotoxicity, our work aimed to investigate the effects of PBP crude extract on testicular damage and sperm parameter alterations caused by CP in mice. Three doses of PBP (50, 100, and 200 mg/kg) were tested in the experimental groups (n = 8 per group), administered concomitantly with 100 mg/kg CP. After 42 days receiving PBP daily and CP weekly, body a

The effects of different humidity, photoperiod, and temperature regimes on the testicular function of the tropical water snake Natrix piscator were investigated in both sham-operated and pinealectomized snakes. Moderate humidity (50 ± 5%) had no effect on the testis, but high humidity (85 ± 5%) increased the testicular weight and activity of sham-operated snakes after 3, 6, and 9 weeks. Exposures to 14L:10D or 24L:0D and high temperature (42 ± 2 °C) inhibited testicular weight and activity in sham-operated snakes, whereas exposure to 10L:14D or 0L:24D and a low temperature (20 ± 2 °C) had no e

Abstract. We studied the effects of one-week ethanol exposure (2.2 g/kg twice daily) on pituitary-gonadal functions of male rats. Because ethanol decreases the food-intake of the animals, diet-restricted rats were used as controls.

In contrast, testicular GnRH receptors of the ethanol group were increased (P <0.05).

Abstract:

Background: Di(2-ethylhexyl) phthalate (DEHP) is the most commonly used as a plasticizer for polyvinyl chloride (PVC), but recently, concern has arisen over the DEHP which may act as a reproductive toxicant to humans. On the other hand, ethanol is the most common supplement of beverages and foods, and so many persons ingest a large quantity of ethanol in daily life. However, interactions between ethanol and DEHP toxicity are not well known. Method: To investigate the effect of dilute ethanol ingestion on the DEHP induced testicular atrophy, rats were received a 1% (w/w) DEHP diet and 2.5 or 5%
