Abstract
The two gonadal steroid hormones, testosterone and estrogen, regulate spermatogenesis by proliferation, differentiation, and apoptosis of testicular cells. It has been reported that heat stress or increased scrotal temperature impairs spermatogenesis in many mammals. Moreover, testicular heat stress has also been shown to suppress testosterone and estrogen biosynthesis. Furthermore, it is well known that testosterone and estrogen are important for testicular activity. Therefore, we hypothesised that exogenous testosterone and estrogen, alone or in combination, might alleviate the testicular activity in a heat-stressed rat model. To the best of our knowledge, this will be the first report of the exogenous treatment of both testosterone and estrogen in the heat-stressed rat. Our results showed that a combined testosterone and estrogen treatment significantly increased sperm concentration. The histopathological analysis also exhibited a normal histoarchitecture in the combined treatment group along with decreased oxidative stress. The improved spermatogenesis in the combined treatment group was also supported by the increase in PCNA, GCNA, tubule diameter, germinal epithelium height, and Johnsen score in the combined treatment group. Furthermore, the combined treatment also increased the expression of Bcl2, pStat3, and active caspase-3 and decreased expression of Bax. Thus, increased proliferation, apoptotic and anti-apoptotic markers, along with improved histology in the combined treatment group suggest that estrogen and testosterone synergistically act to stimulate spermatogenesis by increasing proliferation and differentiation of germ cells and may also remove the heat-induced damaged germ cells by apoptosis. Overall, the final mechanism of testosterone- and estrogen-mediated improvement of testicular activity could be attributed to amelioration of oxidative stress.

Abstract
Nerve growth factor (NGF) plays an important role in regulating the hypothalamus-pituitary-gonadal (HPG) axis. However, the effects of NGF on spermatogenesis remain unclear. This study aimed to assess the potential application of NGF with nasal delivery on spermatogenesis in azoospermic mice. We established a model with azoospermia induced by a single intraperitoneal (i.p.) injection of busulfan. NGF pre-encapsulated with liposomes (25, 50, and 100 μg/kg) was delivered via internasal administration. Three weeks after busulfan injection, NGF treatments were performed twice a week for 8 weeks; the change of sperm quality, testis and epididymis histopathology, and androgenic hormone were analyzed to evaluate sperm regeneration. Furthermore, 30 mg/kg busulfan injection caused severe testicular atrophy of the seminiferous tubules, characterized by a loss of spermatogenic elements and sperms. NGF with nasal administration could significantly upregulate the markers expressing meiotic spermatogonia (Stra8) and spermatocytes (SYCP3), restore spermatogenesis, and improve sperm quality in busulfan-treated mice by increasing the secretion of sexual hormones. The convenient and noninvasive nasal delivery of NGF may be a new potential therapy for spermatogenesis via activating the HPG axis and elevating androgenic hormones. This study opened a new horizon for NGF application in reproductive endocrine.

Abstract
The aim of this study was to investigate the diagnostic value of serum G protein-coupled oestrogen receptor (GPER) levels and their correlation with semen parameters in men with infertility. The participants were divided into two groups as follows: 76 fertile control men (Group 1) and 77 infertile men (Group 2). Semen analysis, hormonal evaluation, serum GPER level and scrotal ultrasound of the participants were evaluated. Follicle-stimulating hormone and total testosterone levels were not significantly different between the groups (p = .413 and p = .535 respectively). The oestradiol level in Group 1 was significantly lower than that in Group 2 (p < .001). The serum GPER level was found to be significantly higher in Group 1 than that of Group 2 (p < .001). GPER levels were positively correlated with the total sperm count, sperm concentration, motility and morphology in Group 2 (r = 0.303, 0.345, 0.260 and 0.322, respectively, p < .001). In this study, GPER levels were positively correlated with sperm parameters, and it was hypothesised that the decrease in GPER expression might be associated with male infertility by adversely affecting spermatogenesis.

Urology 2018; 122:89-96. [PMID: 30171922 DOI: 10.1016/j.urology.2018.08.025] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2018] [Revised: 08/05/2018] [Accepted: 08/21/2018] [Indexed: 11/27/2022]
Abstract
OBJECTIVES To investigate the effect of kallikrein-related peptidase KLK1 on azoospermic mice induced by busulfan and mouse spermatogonial stem cell. METHODS Mice were treated with a single intraperitoneal injection of busulfan, and 4 weeks later, they received a daily intraperitoneal injection of KLK1 at different doses for another 4 weeks. Eight weeks after the busulfan treatment, all mice were sacrificed and their testes were collected for histological evaluation, immunostaining and protein extraction. In vitro, immortalized mouse spermatogonial stem cells, namely C18-4 cells, were treated with KLK1 for proliferation assays. RESULTS Histological evaluation of testes, epididymis and epididymal fluid showed that KLK1-treated mice had better spermatogenesis than the control group. Immunostaining showed that tissue samples from testes of KLK1-treated mice had more PLZF- and SCP3-positive cells per seminiferous tubule as well as more PNA-positive cells in the seminiferous tubules. Western blots revealed higher expression levels of PCNA in KLK1-treated mice than in control mice. C18-4 cells treated with KLK1 had a higher proliferation rate and higher expression levels of PCNA, Cyclin A and Cyclin E, and the level of phosphorylated ERK2 were increased after KLK1 treatment. CONCLUSION Collectively, KLK1 can improve spermatogenesis in azoospermic mice, and KLK1 can promote the proliferation of mouse spermatogonial stem cells via activating ERK1/2 and cell cycle proteins Cyclin A and Cyclin E. This study could offer novel approach and provide new targets for the treatment of azoospermia.
