Premature ovarian insufficiency (POI) patients experience a decline in ovarian function and a reduction in serum reproductive hormones, leading to a significant impact on the outcomes of assisted reproductive technology. Despite the absence of an effective clinical treatment to restore fertility in POI patients, recent research has indicated that cord blood plasma (CBP) derived from human umbilical cord blood (hUCB) may offer therapeutic benefits for various degenerative diseases. The primary aim of this study is to explore approaches for enhancing ovarian function and serum reproductive hormones through the administration of CBP in a murine model.

The primary objective of the study was to assess the values of serum anti-Müllerian hormone (AMH) levels and the combined index for the prediction of number of oocytes retrieved (NOR) and number of good-quality embryos (GQE) in infertile women undergoing IVF/ICSI treatment. A group of 521 infertile women aged 21-46 years were recruited as subject in this study. Serum AMH, hormones, and antral follicle count (AFC) were measured.

Oligozoospermia or low sperm count is a leading cause of male infertility worldwide. Despite decades of work on non-coding RNAs (ncRNAs) as regulators of spermatogenesis, fertilization, and male fertility, the literature on the function of long non-coding RNAs (lncRNAs) in human oligozoospermia is scarce. We integrated lncRNA and mRNA sequencing data from 12 human normozoospermic and oligozoospermic samples and comprehensively analyzed the function of differentially expressed lncRNAs (DE lncRNAs) and mRNAs (DE mRNAs) in male infertility.

Our previous study revealed that melatonin (MLT) protected the quality of cryopreserved ovarian tissues in mice. This work was carried out to examine the role of MLT in inducing HSP90 expression of ovarian tissue for achieving cryoprotection. Pieces of ovarian tissues were obtained from 50 female rats treated with MLT at 0, 0.

Aim of the present study was to explore the evaluative effectiveness of age, ovarian volume (OV), antral follicle count (AFC), serum follicle-stimulating hormone (FSH), anti-Müllerian hormone (AMH), AFC/Age ratio, AMH/Age ratio, FSH/luteinizing hormone (LH) ratio, and ovarian response prediction index (ORPI) to determine which could more advantageously assess ovarian reserve and response.This research enrolled 319 consecutive infertile women who had undergone in vitro fertilization-ET/intracytoplasmic sperm injection (IVF-ET/ICSI) treatments. Abovementioned variables were measured and calculated.

In the field of assisted reproductive technology, female fertility preservation, particularly ovarian tissue cryopreservation in adolescent cancer patients, has attracted much attention. Melatonin (MLT) is well known for its antioxidative and anti-apoptotic properties; however, whether it can ameliorate the cryoinjury and inhibit the generation of reactive oxygen species (ROS) in cryopreserved ovarian tissues (OTs) has not yet been reported. Here, we demonstrated that MLT could protect follicular integrity; prevent cell apoptosis; decrease ROS, malondialdehyde (MDA), and nitric oxide (NO) levels; and increase activities of glutathione peroxidases (GSH-Px), glutathione (GSH), catalase (CAT), and superoxide dismutase (SOD) in cryopreserved OTs.

To investigate the age-related nomograms and change trends of reproductive hormones, and prevalence of androgen deficiency (AD) in middle-aged and aging men from 2 studies.Two cross-sectional studies were conducted at 5-year intervals in Chinese community-dwelling men living in the same area. A total of 434 (Study 1, S1) and 944 (Study 2, S2) men aged 40 to 69 years were recruited as subjects and 59 (S1) and 98 (S2) men aged 20 to 39 years as controls to measure serum reproductive hormone levels.

Objective: To investigate the prevalence of metabolic syndrome (MS) and its relationship with reproductive hormones in adult males in China.

Methods: Using the cluster and stratified sampling methods, we conducted an investigation among 3 600 adult males aged over 20 years in Hebei, Shaanxi and Jiangsu provinces. We obtained their reproductive hormone levels, biochemical indicators and basic body indexes and compared them between the two groups of subjects.

To evaluate and compare left and right testicular tissue histopathology and Johnsen score, and to investigate the necessity for bilateral testicular biopsy. We recruited180 patients with non-obstructiveazoospermia (NOA) on testicular biopsy who had undergonetesticular sperm aspiration (TESA). Pathological sections of testicular tissue were diagnosed by specially-assigned doctors, who evaluated pathological findings, determined the Johnsen score and confirmed for the presence or absence of sperm.

Objective: To investigate the relationship among serum reproductive hormone levels, serum homocysteine (Hcy) levels, metabolic syndrome (MS), and the components of MS in middle-aged and elderly males.

Methods: Using the cluster and stratified sampling methods and a unified structured questionnaire, we conducted a survey among 948 men aged 40 - 80 years in the rural community, measured their basic physical parameters, and obtained their reproductive hormone levels, serum Hcy concentrations, and metabolism-related indicators. We collected 868 valid questionnaires along with their serum samples, divided the subjects into an MS and a non-MS control group in a 1:1 ratio, and measured their serum Hcy concentrations.

Background/aim: The question of whether body mass index (BMI) affects semen quality and male fertility is controversial. The purpose of this research was to determine whether there is a correlation between BMI and semen analysis parameters.

Materials And Methods: A total of 617 male infertility patients were recruited and separated into 3 groups according to BMI values as follows: normal weight group (n = 334), overweight group (n = 220), and obese group (n = 63).

Introduction: The concurrence of chronic diseases and some well-defined risk factors significantly impacts the prevalence of erectile dysfunction (ED).

Aim: To determine whether late-onset hypogonadism (LOH) impacts the prevalence of ED using investigation reproductive health data of middle-aged and aging males in China.

Methods: The reproductive health status of 1498 males, aged 40-69 years, was evaluated using questionnaires of LOH based on the Androgen Deficiency in Aging Males (ADAM) and Aging Male Symptoms scale (AMS), as well as the International Index of Erectile Function-5 (IIEF-5) assessment.

This multi-center, cross-sectional study investigated the association between serum testosterone (T) levels, serum sex hormone-binding globulin (SHBG) levels, and the risk of metabolic syndrome (MS) in 3332 adult Chinese men. The prevalence of MS was 34.7%, and men with MS had lower serum levels of total T (TT) and SHBG than those without MS (P < 0.

Objective: To investigate the changes of serum reproductive hormones with male aging and to compare the differences in the hormone levels among different age groups or between township and rural males of the same age group.

Methods: Using cluster and stratified sampling, we recruited 434 healthy old and middle-aged (40-69 years) males, 198 from the township and 236 from the rural communities. We determined the concentrations of serum total testosterone (tT), luteinizing hormone (LH) and sex hormone binding globulin (SHBG), free testosterone (fT), bio-available testosterone (Bio-T), and obtained the testosterone secretion index (TSI) and free testosterone index (fTI).

The screening questionnaires on late-onset hypogonadism (LOH) in males are being gradually perfected with the progress in the researches on this problem. Among the more commonly used screeners are the Aging Male Symptoms Scale (AMS), Androgen Deficiency in the Aging Males Questionnaire (ADAM) and Massachusetts Male Aging Survey Questionnaire (MMAS), which are intended for the screening or diagnosis of LOH as well as for the evaluation of its therapeutic results. Nowadays LOH-related researches are mostly concentrated on the utilization of the questionnaires, validation of their sensitivity and specificity, correlation of screening outcomes or some items with serum hormone levels, and comparison of different screening questionnaires, etc.
