The novel coronavirus disease (COVID-19) pandemic is emerging as a global health threat and shows a higher risk for men than women. Thus far, the studies on andrological consequences of COVID-19 are limited. To ascertain the consequences of COVID-19 on sperm parameters after recovery, we recruited 41 reproductive-aged male patients who had recovered from COVID-19, and analyzed their semen parameters and serum sex hormones at a median time of 56 days after hospital discharge. For longitudinal analysis, a second sampling was obtained from 22 of the 41 patients after a median time interval of 29 days from first sampling. Compared with controls who had not suffered from COVID-19, the total sperm count, sperm concentration, and percentages of motile and progressively motile spermatozoa in the patients were significantly lower at first sampling, while sperm vitality and morphology were not affected. The total sperm count, sperm concentration, and number of motile spermatozoa per ejaculate were significantly increased and the percentage of morphologically abnormal sperm was reduced at the second sampling compared with those at first in the 22 patients examined. Though there were higher prolactin and lower progesterone levels in patients at first sampling than those in controls, no significant alterations were detected for any sex hormones examined over time following COVID-19 recovery in the 22 patients. Although it should be interpreted carefully, these findings indicate an adverse but potentially reversible consequence of COVID-19 on sperm quality.

BACKGROUND: We aimed to investigate whether various immune-related plasma proteins, alone or in combination with conventional clinical risk factors, can predict spontaneous preterm delivery (SPTD) and intra-amniotic infection in women with premature cervical dilation or a short cervix (≤ 25 mm).METHODS: This retrospective study included 80 asymptomatic women with premature cervical dilation (n = 50) or a short cervix (n = 30), who underwent amniocentesis at 17–29 weeks. Amniotic fluid (AF) was cultured, and maternal plasma was assayed for interleukin (IL)-6, matrix metalloproteinase (MMP)-9, tissue inhibitor of metalloproteinases (TIMP)-1, and complements C3a and C5a, using enzyme-linked immunosorbent assay (ELISA) kits. The primary outcome measures were SPTD at < 32 weeks and positive AF cultures.RESULTS: The plasma levels of IL-6, C3a, and C5a, but not of MMP-9 and TIMP-1, were significantly higher in women with SPTD at < 32 weeks than in those who delivered at ≥ 32 weeks. The women who delivered at < 32 weeks had more advanced cervical dilatation, and higher rates of antibiotic and tocolytic administration and were less likely to be given vaginal progesterone than those who delivered at ≥ 32 weeks. Using a stepwise regression analysis, a combined prediction model was developed, which included the plasma IL-6 and C3a levels, and cervical dilatation (area under the curve [AUC], 0.901). The AUC for this model was significantly greater than that for any single variable included in the predictive model. In the univariate analysis, plasma IL-6 level was the only significant predictor of intra-amniotic infection.CONCLUSION: In women with premature cervical dilation or a short cervix, maternal plasma IL-6, C3a, and C5a levels could be useful non-invasive predictors of SPTD at < 32 weeks. A combination of these biomarkers and conventional clinical factors may clearly improve the predictability for SPTD, as compared with the biomarkers alone. An increased plasma level of IL-6 predicted intra-amniotic infection.

OBJECTIVE: To analyze the correlation of serum progesterone (PROG) level with blood biochemical parameters and common traditional Chinese medicine (TCM) syndromes in male patients with type 2 diabetes mellitus (T2DM). METHODS: We collected the clinical data of 192 male patients with T2DM, who were admitted in the Department of Endocrinology, Nanjing Hospital of Chinese Medical Affiliated to Nanjing University of Chinese Medicine between January, 2018 and March, 2019. The general clinical data, C-peptide level, blood glucose level, glycated hemoglobin (HbA1c), HOMA, blood lipid level, and sex hormones were compared between the patients with normal PROG and elevated PROG levels and also between the patients with two common TCM syndromes, namely and deficiency syndrome and damp- heat accumulation in the spleen syndrome. We further compared the sex hormones, C-peptide level, HOMA, HbA1c, and blood glucose level among the patients with the two TCM syndromes having normal or elevated PROG levels. RESULTS: Compared with those in patients with normal PROG level, BMI, C-peptide, HOMA-β, and HOMA2-IR were significantly lowered and HOMA-IS, E2, and T were significantly increased in patients with elevated PROG level; no statistical differences were found in age, disease duration, waist-to-hip ratio (WHR), smoking history, blood pressure, blood glucose, blood lipids, HbA1c, LH, FSH or PRL between the two groups. Compared with the patients with damp-heat accumulation syndrome group, the patients with and deficiency syndrome were older and had a longer disease duration, a greater BMI, and higher levels of PROG, C-Peptide, HOMA-β, HOMA2-IR and HOMA-IS, but the smoking history, WHR, HbA1c, blood glucose, and sex hormone levels were comparable between the two groups. Among the 4 groups of patients with different PROG levels and TCM syndromes, significant differences were found in the levels of C-peptide, HOMA-β, HOMA-IS, HOMA2-IR, PROG, E2, T, LH and FSH, and the patients with and deficiency syndrome as well as an elevated PROG level had the lowest C-peptide level, HOMA-β and HOMA2-IR and the highest HOMA-IS, PROG, E2, T, LH and FSH. CONCLUSIONS An elevated PROG level is closely related to islet cell dysfunction and TCM syndrome types in male patients with T2DM.

PURPOSE: The aim of this study was to investigate how type I diabetes mellitus (T1D) affects the folliculogenesis and oocyte development, fertilization, and embryo development. MATERIALS AND METHODS: A comparative animal study was conducted using two different mouse models of T1D, a genetic AKITA model and a streptozotocin-induced diabetes model. Ovarian function was assessed by gross observation, immunoblot, immunohistochemistry, oocyte counting, and ELISA for serum hormones (insulin, anti-Mullerian hormone, estradiol, testosterone, and progesterone). Maturation and developmental competence of metaphase II oocytes from control and T1D animals was evaluated by immunofluorescent and immunohistochemical detection of biomarkers and in vitro fertilization. RESULTS: Animals from both T1D models showed increased blood glucose levels, while only streptozotocin (STZ)-injected mice showed reduced body weight. Folliculogenesis, oogenesis, and preimplantation embryogenesis were impaired in both T1D mouse models. Interestingly, exogenous streptozotocin injection to induce T1D led to marked decreases in ovary size, expression of luteinizing hormone/chorionic gonadotropin receptor in the ovaries, the number of corpora lutea per ovary, oocyte maturation, and serum progesterone levels. Both T1D models exhibited significantly reduced pre-implantation embryo quality compared with controls. There was no significant difference in embryo quality between STZ-injected and AKITA diabetic mice. CONCLUSION: These results suggest that T1D affects folliculogenesis, oogenesis, and embryo development in mice. However, the physiological mechanisms underlying the observed reproductive effects of diabetes need to be further investigated.

OBJECTIVETo study the reference ranges of six sex hormones, i.e., luteinizing hormone, follicle-stimulating hormone, progesterone, prolactin, estradiol, and testosterone, for healthy children aged 0-18 years in Shenzhen, China.

METHODSStratified cluster sampling was performed to select 2 178 healthy children aged 0-18 years in the districts of Futian, Luohu, Nanshan, Bao'an, and Longgang in Shenzhen between September 2015 and September 2016. There were 1 219 boys and 959 girls, including 81 neonates, 335 infants, 346 young children, 469 preschool children, 419 school-aged children, and 528 adolescents. The American Beckman DXI800 chemiluminescence meter was used to measure the levels of luteinizing hormone, follicle-stimulating hormone, progesterone, prolactin, estradiol, and testosterone.

RESULTSThere were significant differences in the levels of luteinizing hormone, follicle-stimulating hormone, progesterone, prolactin, estradiol, and testosterone between different age groups (P<0.05). There were also significant differences in the levels of these sex hormones between boys and girls in the same age group (P<0.05). The reference ranges of six sex hormones were established for healthy children aged 0-18 years in Shenzhen based on the levels of these hormones in different age groups.

CONCLUSIONSThere are significant differences in sex hormones between different age groups or sex groups. The reference ranges of six sex hormones established for different sexes or ages have great significance in the diagnosis and treatment of endocrine diseases in children.

Objective: To investigate the dynamic changes of serum reproductive hormone levels in old and middleaged males in health examination and their correlation with age and lipid profile. METHODS: This study included 4 333 men in health examination from January 2011 to December 2014. The men were aged from 40 to 85 years old and divided into seven fiveyearspan age groups. We determined the levels of serum testosterone (T), luteinizing hormone (LH), folliclestimulating hormone (FSH), estradiol (E2), progesterone (P), prolactin (PRL), total cholesterol (TC), triglyceride (TG), lowdensity lipoprotein cholesterol (LDLC), highdensity lipoprotein cholesterol (HDLC), and the testosterone secretion index (TSI = T/LH). We analyzed the obtained data using SPSS Pram, KruskalWallis H test, MannWhitney U test, exponential regression, and Spearman correlation analysis. RESULTS: Statistically significant differences were found in LH, FSH, E2 and TSI among the seven age groups (P< 0.05). The levels of serum LH, FSH and E2 were significantly higher (P< 0.05) while TSI remarkably lower (P< 0.05) in the ≥70 yr group than in the other six groups. The serum T and E2 levels and TSI were markedly lower in the 40－44, 45－49 and 50－54 yr groups in 2014 than in the other three years (P< 0.05), and so were the levels of serum T and TSI in the 55－59 yr group (P< 0.05). The levels of serum LH, FSH and E2 were correlated positively while those of P, PRL and TSI negatively with age. The serum T level was correlated positively with HDLC but negatively with TC, TG and LDLC. The levels of serum LH, FSH and E2 showed a yearly average increase of 1.9%, 2.7% and 0.5%, respectively, while TSI an annual mean decline of 2.0% in the 40－85 yr group. CONCLUSIONS LH, FSH and E2 were increased while TSI decreased with age in the >40 years old males. T and TSI were reduced in the 40－59 years old men from 2011 to 2014, and so was E2 in the 40－54 yr group. Lowlevel testosterone is closely related to dyslipidemia.

OBJECTIVETo observe protective effects of Schisandra extract (SE) on embryotoxicity and reproductive toxicity of early pregnant rats exposed to Benzo[a]pyrene (Bap).

METHODSPregnant rat model was prepared using periodic screening cage method. Totally 50 female pregnant SD rats were divided into five groups by randomized block design according to the weight, i.e., the BaP model group, the low dose SE group, the middle dose SE group, the high dose SE group, the normal control group, 10 rats in each group. Rats in the BaP model group were administered with BaP at a daily dose of 2 mg/kg by gastrogavage. Rats in low, middle, and high dose SE groups were administered by gastrogavage with BaP (at a daily dose of 2 mg/kg) plus SE at a daily dose of 40, 200, and 1 000 mg/kg, respectively. Equal volume of olive oil was administered to rats in the normal control group by gastrogavage. All medication was performed for 8 successive days. Changes of rat body weight in each period were observed. The uterus embryonic total quality and ovary quality were measured, and organ index calculated. The number of corpus luteum, the number of embryo implantation, and the number of absorbed embryo were statistically calculated respectively. The implantation rate and the absorbed embryos rate were calculated. Serum levels of human chorionic gonadotrophin β (β-HCG) and progesterone (PROG) were detected by ELISA.

RESULTSCompared with the normal control group, the weight of 9-day pregnant rats, the number of embryo implantation, the uterus embryonic total index, ovary index, serum levels of β-HCG and PROG all decreased in the Bap model group with significant difference (P < 0.05, P < 0.01). Compared with the Bap model group, body weight, the uterus embryonic total index, and the PROG level increased in 3 dose SE groups (P < 0.05, P < 0.01). Ovary index and serum β-HCG increased in middle and high dose SE groups (P < 0.05, P < 0.01). The number of implantation obviously increased in the high dose SE groups (P < 0.01).

CONCLUSIONSE could reduce the embryotoxicity and reproductive toxicity of early pregnant rats exposed to Benzo[a]pyrene.

OBJECTIVETo explore the protective effect of electroacupuncture (EA) pretreatment on ovarian function in rats with ovulation induction.

METHODSThirty SD female rats were numbered according to random number table. According to vaginal smear method, rats of estrus were divided into a normal group (10 rats) and cohabitated with male SD rats with the proportion of 1:1. With computer-generated random number, the remaining rats were divided into a model group and an EA group, 10 rats in each one. The model of superovulation was established with pregnant mare serum gonadotropin (PMSG) and human chorionic gonadotropin (HCG) in the model group and EA group. Before model establishment and cohabitation, rats in the EA group were treated with EA at "Guanyuan (CV 4)" and "Sanyinjiao (SP 6)", once for 15 min, for consecutive 7 days. Rats in the normal group and model group received no further treatment. The third day 23:00 pm after cohabitation, blood samples in three groups were collected to test the level of estradiol (E₂) and progesterone (P). After the rats were sacrificed, the HE staining method was applied to observe the morphological changes of ovarian tissue; the immunohistochemical method was applied to measure the expression of vascular endothelial growth factor (VEGF) and its receptor VEGFR-2; the real-time quantitative PCR technique was applied to measure the gene expression of VEGF and VEGFR-2.

RESULTSThe number of ovarian follicle in the EA group was higher than that in the model group and normal group (all P < 0.05); the ratio of corpus luteum size to ovarian size in the EA group was lower than that in the model group (P < 0.01). The ratio of plasma estradiol to progesterone in the EA group tended to be normal group (P < 0.05) and lower than that in the model group (P < 0.01). The protein expression of VEGF and VEGFR-2 in lutein granulosa cell and follicular fluid in the EA group was lower than that in the model group (P < 0.05); gene level of VEGF and VEGFR-2 in ovarian tissue in the EA group was lower than that in the model group (P < 0.05, P < 0.01).

CONCLUSIONEA pretreatment has certain protective effect on ovarian function in rats with ovulation induction, which is likely to be related to regulation of VEGF and its receptor.

BACKGROUNDMenopausal hormone therapy (MHT) has been proven to have beneficial effects on several components of metabolic syndrome. However, the effects vary according to different regimens, dosages, and duration of MHT. The aim of the study was to evaluate the effect of standard-dose 0.625 mg conjugated equine estrogen (CEE) and half-dose 0.3 mg CEE daily with different progestogens in a continuous sequential regimen on postmenopausal metabolic parameters in generally healthy postmenopausal women.

METHODSA prospective, open-label, randomized controlled clinical trial was conducted between February 2014 and December 2015. Totally 123 Chinese postmenopausal women with climacteric symptoms were included in this study and were randomly assigned to three groups: Group A received CEE 0.3 mg/micronized progesterone (MP) 100 mg daily; Group B received CEE 0.625 mg/MP 100 mg daily; and Group C received CEE 0.625 mg/dydrogesterone 10 mg daily. Drugs were given in a continuous sequential pattern. The duration of treatment was 12 months. Clinical, anthropometrical, and metabolic variables were measured. Data were analyzed according to intention-to-treat analysis, using Student's t-test and analysis of variance.

RESULTSA total of 107 participants completed the 12-month follow-up and were included in the data analysis. At 12 months of treatment, high-density lipoprotein cholesterol and apolipoprotein A significantly increased, and low-density lipoprotein cholesterol, fasting glucose, and glycosylated hemoglobin significantly decreased in Groups B and C, compared with baseline (all P < 0.05). Among the three groups, only Group C showed significantly increased triglycerides compared with baseline (1.61 ± 0.80 mmol/L vs. 1.21 ± 0.52 mmol/L, P = 0.026). Each group showed a neutral effect on total cholesterol, lipoprotein A, apolipoprotein B, and fasting insulin levels. No cardiovascular and venous thromboembolic events occurred in the three groups.

CONCLUSIONSAmong Chinese postmenopausal women, half-dose CEE was not sufficient to induce a favorable lipid and carbohydrate profile compared with standard-dose CEE. Adding natural MP may counterbalance the TG-increasing effect of CEE.

It is to observe the therapeutic action of Guizhi Fuling capsule and the combination of active ingredients on model rats with uterine leiomyoma. The hysteromyoma rats models was established in rats by loading eatrogen, to observe the effect on pathological condition of uterus, uterus wet weight, the content of estradiol and progesterone. Guizhi Fuling capsule and the combination of active ingredients remarkably decreased uterus weight, restrained the excess proliferation of the smooth muscle of uterus, decreased the estraiol and progesterone in blood serum. Guizhi Fuling capsule and the combination of active ingredients can restrain the formation of hysteromyoma in a dose-dependent manner. Perhaps the combination of active ingredients is the material foundation of antihysteromyoma.
