What is the effect of Tribulus terrestris on testicular morphology and sperm production? An experimental study in the rat model
The objective of this study was to investigate whether treatment with Tribulus terrestris (Tt) has any impact on the testicular morphology and function in a rodent model. Twenty male rats were divided into a control group and a group receiving 100 mg kg−1 body weight of Tt supplementation. After 40 days of experiment, the animals were submitted to euthanasia; epididymal tail spermatozoa were collected; and spermatozoa concentration, motility, and viability were analyzed. In addition, testicles were collected and processed for histomorphometrical analyses. Data were compared using the Student's t-test and considered significant when P < 0.05. Spermatozoa concentration, motility, and viability showed no difference between the groups. Further, testicular weight and volume, seminiferous tubule diameter, tunica propria surface density, seminiferous epithelium surface density, and intertubular compartment surface density were statistically similar between the groups. However, seminiferous epithelium height and tubular lumen surface density were augmented in animals treated with Tt. Treatment with Tt does not cause a major impact on testicular morphology, promoting only subtle modifications. No difference on spermatozoa parameters was observed.
Protective Effect of Lycopene on Ifosfamide-Induced Mitophagy through Pink, Parkin, and LC3-I/II Pathway in Testicular Tissue
Ifosfamide (IFO) is a widely used chemotherapeutic agent that exerts cytotoxic effects through various mechanisms, including the induction of apoptosis and oxidative stress. However, its use is associated with detrimental effects on male reproductive health, including mitochondrial dysfunction and oxidative stress-induced damage. Mitophagy, a selective autophagic process, plays a crucial role in maintaining mitochondrial homeostasis during spermatogenesis. This study aimed to investigate the potential protective effect of lycopene against IFO-induced mitophagy in testicular tissue. We evaluated the expression levels of key mitophagy regulators Pink1, Parkin, and LC3-I/ II in testicular tissue of rats treated with IFO alone or in combination with lycopene. In this experimental study, 24 mature male Wistar rats (250 g ± 25) were divided into control (received normal saline), IFO-sole (received 250 mg/kg, single dose, ip), lycopene (25 mg/kg, orally), and IFO+lycopene groups. Following 60 days, the rats were euthanized and the testicles were dissected out. The expression levels of and were evaluated using qRT-PCR and immunohistochemistry (IHC) techniques. Our findings demonstrated that IFO significantly upregulated , and expression at both mRNA and protein levels compared to controls. Conversely, lycopene administration mitigated these increases induced by IFO, suggesting its potential to attenuate IFO-induced mitophagy. Immunohistochemistry analysis confirmed the protective effect of lycopene, showing reduced expression levels of , and in the presence of lycopene following IFO treatment. These results underscore lycopene's role as a potent protective agent that can mitigate IFO-induced mitophagy in testicular tissue. Further research into the underlying mechanisms of lycopene's protective effects will be crucial for developing therapeutic strategies to preserve male fertility during IFO treatment.

Endocrine-disrupting chemicals (EDCs) and cancer: new perspectives on an old relationship
Purpose Environmental endocrine-disrupting chemicals (EDCs) are a mixture of chemical compounds capable to interfere with endocrine axis at different levels and to which population is daily exposed. This paper aims to review the relationship between EDCs and breast, prostate, testicle, ovary, and thyroid cancer, discussing carcinogenic activity of known EDCs, while evaluating the impact on public health. Methods A literature review regarding EDCs and cancer was carried out with particular interest on meta-analysis and human studies. Results The definition of EDCs has been changed through years, and currently there are no common criteria to test new chemicals to clarify their possible carcinogenic activity. Moreover, it is difficult to assess the full impact of human exposure to EDCs because adverse effects develop latently and manifest at different ages, even if preclinical and clinical evidence suggest that developing fetus and neonates are most vulnerable to endocrine disruption. Conclusion EDCs represent a major environmental and health issue that has a role in cancer development. There are currently some EDCs that can be considered as carcinogenic, like dioxin and cadmium for breast and thyroid cancer; arsenic, asbestos, and dioxin for prostate cancer; and organochlorines/organohalogens for testicular cancer. New evidence supports the role of other EDCs as possible carcinogenic and pregnant women should avoid risk area and exposure. The relationship between EDCs and cancer supports the need for effective prevention policies increasing public awareness.
Choosing Castration: A Thematic Analysis of the Perceived Pros and Cons of Genital Injuries and Ablation by Men Who Voluntarily Sought Castration
Some men elect castration voluntarily without any clear medical reason. Here we aim to document their perception of genital ablation and injuries to better understand their motivations for castration. Participants completed an online survey with open-ended questions related to their perspectives on castration, genital ablation, and genital injuries. Thematic analyses were performed on the responses to these questions. Responses were obtained from 208 male castrated individuals (51.9 ± 16.0 years old). Among these, 154 were physically castrated, 36 chemically castrated, and 18 nullified (had testicles and penis removed). The majority learned about castration from media (55.8%) or animal castration (23.4%). The circumstances when they first wanted to be castrated varied greatly. Most (46.3%) wished to achieve an idealized self motivated by gender dysphoria, body integrity dysphoria, or wanting to be conspicuously non-sexual. The top themes we identified related to the respondents’ perceptions of the pros of genital ablation were physical appearance, psychological benefit (i.e., a “eunuch calm”), and being non-sexual. Conversely, themes related to the cons they saw in having no genitals ranged from no disadvantages to loss of sexual/reproductive capability. Some perceived performing genital injury as a step toward ultimate castration or nullification. The respondents similarly varied in whether they saw any loss in having non-functional testicles. Perceptions in this regard appeared to differ depending on whether the respondents were taking supplemental androgens post-castration. Motivations for castration vary greatly between individuals. Clinicians need to understand men’s diverse perceptions on castration in order to provide appropriate care for individuals with strong castration desire.
Risk factors for dysgeusia during chemotherapy for solid tumors: a retrospective cross-sectional study
Purpose This study retrospectively analyzed the risk factors for transchemotherapy dysgeusia. Methods Before each chemotherapy cycle, patients were routinely evaluated for the presence/severity of dysgeusia based on the Common Terminology Criteria for Adverse Events (CTCAE) v5.0 scale for adverse effects and graded as follows: 0, no change in taste; 1, altered taste with no impact on eating habits; or 2, altered taste with an impact on eating habits. Information from 2 years of evaluations was collected and patient medical records were reviewed to obtain data on chemotherapy cycle, sex, age, body mass index, body surface area, primary tumor, chemotherapy protocol, and history of head and neck radiotherapy. The X 2 test and multinomial logistic regression were used for statistical analysis (SPSS 20.0, p < 0.05). Results Among 7425 total patients, 3047, 2447, and 1931 were evaluated after the first, second, and third chemotherapy cycles, respectively. One-fifth of the patients (19.0%) presented a significant loss of taste, with 1118 (15.0%) showing grade 1 dysgeusia and 442 (6.0%) showing grade 2 dysgeusia. The chemotherapy duration ( p < 0.001), female sex ( p < 0.001), location of the primary tumor in the uterus ( p = 0.008), head and neck ( p = 0.012), and testicles ( p = 0.011), and use of ifosfamide ( p = 0.009), docetaxel ( p = 0.001), paclitaxel ( p < 0.001), pertuzumab ( p = 0.005), bevacizumab ( p < 0.001), and dacarbazine ( p = 0.002) independently increased the risk of dysgeusia. In head and neck tumors, a previous history of radiotherapy significantly increased the prevalence of dysgeusia ( p = 0.017), and the use of cisplatin ( p = 0.001) increased this prevalence. Conclusion Cycles of chemotherapy, sex, uterine cancer, head and neck tumors, testicular cancer, ifosfamide, docetaxel, paclitaxel, pertuzumab, bevacizumab, and dacarbazine increase the risk of dysgeusia.
Zinc and Its Impact on the Function of the Testicle and Epididymis
Zinc (Zn) is an essential trace element; it exhibits a plethora of physiological properties and biochemical functions. It plays a pivotal role in regulating the cell cycle, apoptosis, and DNA organization, as well as in protein, lipid, and carbohydrate metabolism. Among other important processes, Zn plays an essential role in reproductive health. The ZIP and ZnT proteins are responsible for the mobilization of Zn within the cell. Zn is an inert antioxidant through its interaction with a variety of proteins and enzymes to regulate the redox system, including metallothioneins (MTs), metalloenzymes, and gene regulatory proteins. The role of Zn in the reproductive system is of great importance; processes, such as spermatogenesis and sperm maturation that occur in the testicle and epididymis, respectively, depend on this element for their development and function. Zn modulates the synthesis of androgens, such as testosterone, for these reproductive processes, so Zn deficiency is related to alterations in sperm parameters that lead to male infertility.
Is There a Relationship Between Prenatal Dexamethasone and Postnatal Fructose Overexposure and Testicular Development, Function, and Oxidative Stress Parameters in Rats?
Prenatal glucocorticoid overexposure alters the developmental program of fetal reproductive organs and results in numerous changes that can lead to various disorders later in life. Moderate fructose consumption during childhood and adolescence may impair the development and function of reproductive organs. The aim of this study was to investigate the effects of prenatal dexamethasone (Dx) exposure in combination with postnatal fructose overconsumption on testicular development and function in fetal and adult male rat offspring. Pregnant female rats were treated with a subcutaneous injection of Dx at a dose of 0.5 mg/kg/day on gestation days 16, 17, and 18, and the effects on fetal growth and testicular development were analyzed. Spontaneously born male offspring were fed 10% fructose in drinking water until the age of 3 months. Prenatal exposure to Dx led to a reduction in fetal weight and testicular volume. However, testicular development normalized by adulthood, with testosterone levels decreasing. After moderate fructose consumption, impaired redox homeostasis and structural changes in the testicles and decreased testosterone levels were observed, indicating reduced testicular function. The results suggest that the synergistic effect of prenatal Dx exposure and moderate postnatal fructose consumption leads to more deleterious changes in testicular tissue.
Antipsychotic Drug-Mediated Adverse Effects on Rat Testicles May Be Caused by Altered Redox and Hormonal Homeostasis
Sexual dysfunction, as a noticeable adverse effect of atypical antipsychotic drugs (APDs) for the treatment of schizophrenia, has not been investigated in detail. A study was undertaken to investigate whether 28-day long treatment with clozapine, ziprasidone or sertindole (using a recommended daily dose for atypical antipsychotic therapy), induced histopathological changes both in rat testicles and prostate, changed the activity of the antioxidant defence system and altered blood testosterone and prolactin. Clozapine, ziprasidone and sertindole induced histopathological changes in rat testicular tissue, which could be attributed to a disturbed testicular antioxidant defence system in addition to an altered prolactin to testosterone ratio. None of the APD treatments induced histopathological changes in prostate. Our results demonstrate that APDs have the capacity to change both redox and endocrinological balance. One or both outcomes could underline testicular degeneration and disturbed spermatogenesis.
Computed Tomography Assessment of Retained Testes in Dogs
Cryptorchidism consists in the failure of one or both testicles to fully descend into the scrotum. The position of the retained testes can be abdominal or inguinal and may occur unilaterally or bilaterally. This retrospective, multi-center study aimed to describe the computed tomography (CT) features of retained testes in dogs. Nineteen CT scans of dogs, with either unilateral or bilateral cryptorchidism, were analyzed with both pre- and post-contrast imaging. The location, size, shape, margins, homogeneous parenchyma, and density calculated were examined with the Hounsfield unit. Statistical analyses were performed to assess the differences between the scrotal (ST) and undescended testes (UT) and to detect any correlation between the features, ages, and size of the dog. CT identified the retained testes and provided enhanced three-dimensional visualization compared to traditional ultrasound. This study revealed that the UT were significantly smaller than ST, with UT measuring around 70% of ST size. Additionally, the UT exhibited increased density in both pre- and post-contrast scans, potentially due to the reduced or absent spermatogenesis or to histological changes occurring in the parenchyma. While CT showed clear advantages, such as three-dimensional spatial resolution and deeper tissue penetration, limitations such as general anesthesia and radiation exposure should also be considered. However, the present study showed that CT could serve as a valuable second step tool in cases where ultrasound fails, particularly in challenging anatomical situations.
