Abstract
Testicular hyperthermia has been noted in men who work in high ambient temperatures. Scrotal temperatures above the normal range caused germ cell loss in the testes and resulted in male subfertility. In adult male rats, exercising at a higher environmental temperature (36 °C with relative humidity of 50%, 52 min) caused exertional heat stroke (EHS) characterized by scrotal hyperthermia, impaired sperm quality, dysmorphology in testes, prostates and bladders, and erectile dysfunction. Here, we aim to ascertain whether hyperbaric oxygen preconditioning (HBOP: 100% O2 at 2.0 atm absolute [ATA] for 2 h daily for 14 days consequently before the onset of EHS) is able to prevent the problem of EHS-induced sterility, testes, prostates, and bladders dysmorphology and erectile dysfunction. At the end of exertional heat stress compared to normobaric air (NBA or non-HBOP) rats, the HBOP rats exhibited lower body core temperature (40 °C vs. 43 °C), lower scrotal temperature (34 °C vs. 36 °C), lower neurological severity scores (2.8 vs. 5.8), higher erectile ability, (5984 mmHg-sec vs. 3788 mmHg-sec), higher plasma testosterone (6.8 ng/mL vs. 3.5 ng/mL), lower plasma follicle stimulating hormone (196.3 mIU/mL vs. 513.8 mIU/mL), lower plasma luteinizing hormone (131 IU/L vs. 189 IU/L), lower plasma adrenocorticotropic hormone (5136 pg/mL vs. 6129 pg/mL), lower plasma corticosterone (0.56 ng/mL vs. 1.18 ng/mL), lower sperm loss and lower values of histopathological scores for epididymis, testis, seminal vesicle, prostate, and bladder. Our data suggest that HBOP reduces body core and scrotal hyperthermia and improves sperm loss, testis/prostate/bladder dysmorphology, and erectile dysfunction after EHS in rats.

Abstract
Over the past years, several studies have also reported the adverse effects of hyperthermia on normal testicular tissues in several species including mice, rats, and humans. These deleterious impacts include temporarily drop in relative weight of testis along with a temporary partial or complete infertility. Sambucus nigra, also known as elderberry or sweet elder, is a source of bioactive compounds that has drawn growing attention for its potential beneficial effects in preventing and treating several diseases. This experimental research divided 30 mice into the following three groups: (1) control, (2) hyperthermia, and (3) hyperthermia receiving elderberry diet for 35 days. Scrotal hyperthermia was induced by water bath with 43 °C for 30 min. Then, the mice were euthanized, and their sperm samples were collected for sperm parameters analysis. Then, we took the testis samples for histopathological experimentations, immunohistochemistry against TNF-α and caspase-3 and serum testosterone, FSH and LH levels. Our outputs indicated that elderberry diet could largely improve the sperms parameters and stereological parameters, like spermatogonia, primary spermatocyte, round spermatid, and Leydig cells together with an increasing level of the serum testosterone compared to the scrotal hyperthermia induced mice. In addition, it was found that the expression of TNF-α and caspase-3 significantly decreased in the treatment groups by elderberry diet compared to the scrotal hyperthermia-induced mice. In conclusion, it could be concluded that elderberry diet may be regarded as an alternative treatment for improving the spermatogenesis process in the scrotal hyperthermia induced mice.

Abstract
Exposure to heat in the male reproductive system can lead to transient periods of partial or complete infertility. The current study aimed to examine the beneficial effects of Fisetin against spermatogenic disorders in mice affected by long-term scrotal hyperthermia. For this purpose, hyperthermia was induced daily by exposure to the temperature of 43 °C for 20 min for 5 weeks. Except for the Healthy group, six other groups were exposed to heat stress: two treated groups including Preventive and Curative which received oral administration of fisetin (10 mg/kg/day) starting immediately before heat exposure and 15 consecutive days after the end of the heat exposure, respectively. And for each treated group, two groups including Positive Control (Pre/Cur+PC group) and vehicle (Pre/Cur+DMSO group) were considered. Our results showed that the testicular volume; the density of spermatogonia, primary spermatocyte, round spermatid, and Sertoli and Leydig cells; and sperm parameters, as well biochemical properties of the testis tissue, were remarkably higher in both Preventive and Curative groups compared to the other hyperthermia-induced groups and were highest in Preventive ones. Unlike the c-kit gene transcript which was significantly increased in the Fisetin treatment groups (specially the Preventive group), the expression of HSP72 and NF-kβ genes, Caspase3 protein, and DFI in sperm cells were significantly more decreased in Preventive and Curative groups compared to other hyperthermia-induced groups and were lowest in Preventive ones. Overall, Fisetin exerts preventive and curative effects against spermatogenic disorders induced by long-term scrotal hyperthermia.
