Acta Physiologica Sinica 2025;77(1):151-166
A disintegrin and metalloproteinase with thrombospondin-like motifs (ADAMTS) represent a diverse family of secreted metalloproteinases, comprising 19 distinct members categorized into five groups based on their substrate specificity: proteoglycanases, procollagen N-peptidases, von Willebrand factor-cleaving protease, cartilage oligomeric matrix proteases and other proteases. Among these, ADAMTS proteoglycanases predominantly target hyalectans, pivotal components in extracellular matrix (ECM) remodeling and inflammation. Dysfunction of ADAMTS proteoglycanases disrupts the structure and function of hyalectans, thereby perturbing ECM homeostasis, resulting in reproduction disorders, including abnormal follicular development, ovulation dysfunction, impaired implantation, placentation and preterm labor. Hence, investigation of the role of ADAMTS proteoglycanases offers valuable insights into the molecular mechanisms underlying the physiological or pathological processes within the female reproductive system, thereby paving the way for innovative strategies in predicting, preventing and treating reproductive system diseases. This review summarizes the recent research advances in the structure and regulation of ADAMTS proteoglycanases and their role in female reproductive system.

This report details the case of a 24-year-old Filipino individual born with ambiguous genitalia, assigned female at birth, and raised as such. Around the age of 13, the patient began to develop secondary male characteristics. Medical assessment was postponed until the onset of abdominal pain led the patient to seek consultation. Cytogenetic testing revealed a sex chromosome disorder of sexual development with a mosaic karyotype of 45,X/45,X,del(X)(q13). Imaging, surgical exploration, and histopathologic evaluation confirmed that a pelvoabdominal mass originated from the left ovary and was a mixed germ cell tumor containing yolk sac tumor and mature teratoma components. At presentation, the patient also reported symptoms consistent with gender dysphoria. This case highlights the wide phenotypic variability of mosaic Turner syndrome and reinforces the importance of accurate neonatal sex assignment in individuals with DSD. It further emphasizes the need for healthcare providers to remain vigilant for such presentations to enable prompt, tailored, and comprehensive management.

This study aimed to investigate the relationship between the promoting effect of Zuogui Pills on ovarian and vaginal angiogenesis in early-aging rats and mobilization factors granulocyte-macrophage colony-stimulating factor(GM-CSF), stromal cell-derived factor-1(SDF-1), and their receptors of endothelial progenitor cells(EPCs) and explore the mechanism of Zuogui Pills in improving reproductive hypofunction in early-aging rats. Ultra-high performance liquid chromatography-tandem mass spectrometry(UHPLC-MS/MS) was used to analyze the chemical components of the extract of Zuogui Pills. Forty 14-month-old female early-aging rats with estrous cycle disorder were randomly divided into a blank group, a conjugated estrogen group(conjugated estrogen suspension, 65 μg·kg~(-1)), and low-(11 g·kg~(-1)) and high-dose(33 g·kg~(-1)) Zuogui Pills groups, with 10 rats in each group. In addition, 10 4-month-old female rats were assigned to the youth control group. The rats in the blank group and the youth control group were treated with 20 g·kg~(-1) distilled water by gavage, while those in the groups with drug intervention were treated with corresponding drugs by gavage, once a day for 15 days. Enzyme-linked immunosorbent assay(ELISA) was used to detect the levels of SDF-1 and GM-CSF in the mobilization of EPCs in serum. Hematoxylin-eosin(HE) staining was used to observe the changes in the number of ovarian follicles at all levels and corpus luteum, the number of vaginal epithelial layers, the number of vaginal folds, and the blood vessels of ovarian and vaginal tissues in the groups with drug intervention. Western blot was used to detect the expression of ER, GM-CSFR, CXCR4, and CXCR7 proteins in ovarian and vaginal tissues. As revealed by the results, the blank group showed decreased number of corpus luteum, gro-wing follicles at all levels, and blood vessels(P<0.05), decreased thickness of vaginal mucosa, the number of epithelial layers, the number of vaginal folds, and the number of vessels in the lamina propria(P<0.05), reduced content of SDF-1 and GM-CSF in the peripheral blood(P<0.05), and down-regulated levels of ER, CXCR4, CXCR7, and GM-CSFR proteins in ovarian and vaginal tissues(P<0.05). The groups with drug intervention showed increased number of growing follicles at all levels, corpus luteum, and blood vessels(P<0.05), decreased number of atresia follicles(P<0.05), increased thickness of vaginal mucosa, the number of epithelial layers, the number of vaginal mucosal folds, and the number of blood vessels in the lamina propria(P<0.05), increased content of SDF-1 and GM-CSF in the peripheral blood(P<0.05), and up-regulated levels of ER, CXCR4, CXCR7, and GM-CSFR proteins in ovarian and vaginal tissues(P<0.05). This experiment suggests that Zuogui Pills may promote ovarian and vaginal angiogenesis and improve the reproductive function of early-aging rats by up-regulating the levels of mobilization factors SDF-1, GM-CSF, and their receptors of EPCs.

Chlamydia trachomatis (CT) infection is the most prevalent sexually transmitted bacterial disease worldwide. However, unlike that in female infertility, the role of CT infection in male infertility remains controversial. The objective of this retrospective study was to explore the impacts of CT infection in the genital tract on sperm quality, sperm acrosin activity, antisperm antibody levels, and inflammation in a large cohort of infertile males in China. A total of 7154 semen samples were collected from infertile male subjects, 416 of whom were CT positive (CT+ group) and 6738 of whom were CT negative (CT- group), in our hospital between January 2016 and December 2018. Routine semen parameters (semen volume, pH, sperm concentration, viability, motility, morphology, etc.), granulocyte elastase levels, antisperm antibody levels, and sperm acrosin activity were compared between the CT+ and CT- groups. Our results showed that CT infection was significantly correlated with an abnormally low semen volume, as well as an increased white blood cell count and granulocyte elastase level (all P < 0.05) in the semen of infertile males; other routine semen parameters were not negatively impacted. The antisperm antibody level and sperm acrosin activity were not affected by CT infection. These findings suggested that CT infection might contribute to inflammation and hypospermia but does not impair sperm viability, motility morphology, and acrosin activity or generate antisperm antibodies in the infertile males of China.

Genital dissatisfaction is well known in female and adults. Less is known about male adolescents and their genital satisfaction. The aim of this study was to investigate and report the role of surgery in male adolescents to improve the evaluation of their genitalia. We considered all patients treated for external genital pathology in the period of adolescence. Inclusion and exclusion criteria were created. Patients underwent an evaluation test before and after surgery. During the study period, 137 patients were treated, and at the end of the study, 98 cases were considered for analysis. The most frequent pathologies were webbed penis and penile curvature. A postoperative score improvement was noted and patients with concealed penis and webbed penis showed a better postoperative outcome. Overweight was considered an important factor associated with a worse preoperative score. Evaluation of the external genitalia is important in adolescents, and it is an understudied problem. Overweight may be associated with a worse evaluation of one's genital and should be clinically considered to avoid related social problems in adulthood. Therefore, cosmetic genital surgery should be considered even in male adolescents.

The aim of this paper was to observe the toxic effect of Tripterygium Glycosides Tablets( TG) on the reproductive system of Ⅱ type collagen induced arthritis( CIA) male rats,and to explore the toxic mechanism preliminarily. Fifty SD rats were randomly divided into normal control group( Con),model group( CIA),Tripterygium Glycosides Tablets clinical equivalent dose groups of 1,2,4 times( 9,18,36 mg·kg-1),10 rats in each group,and were given by gavage once a day for 42 days after the first immunization.The organ indexes of uterine and ovarian were calculated on days 21 and 42. Histopathological and morphological changes of uterine and ovarian were observed under optical microscope. The concentration of estradiol( E2),follicle-stimulating hormone( FSH),luteinizing hormone( LH),17α-hydroxylase( CYP17 A1) and cytochrome P450 19 A1( CYP19 A1) in serum were detected by ELISA. Immunohistochemistry was used to observe the expression of Bax and Bcl-2 related proteins in the apoptosis pathway of uterus and ovary. The results showed that compared with the Con group,CIA group could reduce the number of uterine glands( P<0.05),but no significant changes were observed in other groups. Compared with the CIA group,there were no significant changes in the coefficients of uterus and ovary in the Tripterygium Glycosides Tablets groups. The number of uterine glands,total follicles in the ovary,mature follicles and corpus luteum,the distribution of blood vessels and mitochondria had a certain inhibitory trend,and also slightly increased the number of atresia follicles,but the histopathological quantitative indicators were not statistically different. Except that 2 times clinical dose of Tripterygium Glycosides Tablets could significantly reduce the content of CYP19 A1( P<0. 05) after 42 d administration,there were no significant changes in serum estrogen E2,FSH,LH and estrogen synthesis key enzymes CYP17 A1 in each administration group. Medium and high doses of Tripterygium Glycosides Tablets could increase the expression of apoptotic protein Bax in uterine and ovarian tissues( P<0. 05,P<0. 01),and all the administration groups could inhibit the expression of apoptotic inhibiting protein Bcl-2( P <0. 05,P<0. 01,P<0.001),42 d was more obvious than 21 d. In conclusion,4 times and less than 4 times Tripterygium Glycosides Tablets did not cause obvious toxicity and histopathological changes in the reproductive organs of CIA rats,but it could reduce the level of serum estrogen synthesis key enzyme CYP19 A1 and affect the content of apoptosis-related proteins Bax and Bcl-2 in uterus and ovary tissues. The relevant mechanism needs further study.

Tripterygium Glycosides Tablets has good anti-inflammatory and immunomodulatory activities,but its reproductive damage is significant. Previous studies of the research group have found that Cuscutae Semen flavonoids can improve spermatogenic cell damage caused by Tripterygium Glycosides Tablets by regulating spermatogenic cell cycle,apoptosis and related protein expression,but the mechanism of action at the gene level is still unclear. In this study,Illumina high-throughput sequencing platform was applied in transcriptional sequencing of spermatogenic cells of rats after the intervention of Cuscutae Semen flavonoids and Tripterygium Glycosides Tablets. Differentially expressed genes were screened out and the GO enrichment and KEGG pathway analysis of differentially expressed genes were conducted to explore the mechanism of Cuscutae Semen flavonoids in improving reproductive injury caused by Tripterygium Glycosides Tablets. The results showed that 794 up-regulated genes and 491 down-regulated genes were screened in Tripterygium Glycosides Tablets group compared with the blank group. Compared with Tripterygium Glycosides Tablets,440 up-regulated genes and 784 down-regulated genes were screened in the Cuscutae Semen flavonoids+Tripterygium Glycosides Tablets group. Among them,the gene closely related to reproductive function is DNMT3 L. Analysis of GO function and KEGG signaling pathway enrichment showed that the above differentially expressed genes were mainly enriched in cell,cell process,catalytic activity,binding,ovarian steroid synthesis,thyroid hormone and other functions and pathways. The thyroid hormone signaling pathway was the common enrichment pathway of the two control groups. In a word,Cuscutae Semen flavonoids has a good treatment effect on male reproductive damage caused by Tripterygium Glycosides Tablets. The mechanism may be closely related to up-regulation of DNMT3 L genes and intervention of thyroid hormone signaling pathway. At the same time,the discovery of many different genes provides valuable information for study on the mechanism of Cuscutae Semen flavonoids and Tripterygium Glycosides Tablets compatibility decreasing toxicity and increasing efficiency.
