icies which change the economic and social conditions of families could prevent increasing birth intervals and influence the fertility rate.
The analysis of birth interval patterns using an appropriate statistical method provides important information for health policymakers. Based on the results of this study, younger women delayed their childbearing more than older women. Migrant women, unemployed women and women who live in developing regions gave birth to their second child sooner than non-migrant employed women, and women who lived in more developed regions. The implementation of policies which change the economic and social conditions of families could prevent increasing birth intervals and influence the fertility rate.
We aimed to compare the effects of using high-fat (HF) and advanced glycation end-products (AGEs) containing dietsto induce obesity and diabetes on sperm function in mice.
In this experimental study, twenty-five 4-week old C57BL/6 mice were divided into 5 groups and were fed with control, 45% HF, 60% HF, 45% AGEs-HF, or 60% AGEs-HF diet. After 28 weeks, fast blood sugar, glucose intolerance, insulin concentration, homeostatic model assessments (HOMA) for insulin resistance (IR) and HOMA for beta cells (HOMA beta) from systematic blood were assessed. In addition, body weight, morphometric characteristics of testes, sperm parameters, DNA damage (AO), protamine deficiency (CMAA3), and sperm membrane (DCFH-DA) and intracellular (BODIPY) lipid peroxidation were measured.
Body mass and fasting blood sugar increased significantly in all experimental groups compared to the control group. Insulin concentration, glucose intolerance, HOMA IR, and HOMA beta were also increased significantly with higher levels of famined parameters are lessthan those in HF diets. One possible reason is detoxification through the activation of the protective glyoxalase pathway asthe result of the chronic AGEs increase in the body.
Because of the widespread use of organophosphate (OP) pesticides in agriculture, they are major environmental contaminants in developing countries. OP pesticides decrease sperm concentration and affect its quality, viability, and motility. studies have demonstrated the association between abnormal semen analysis and OP pesticides exposure among the high-risk population. Asthere is limited data on the percentage of OP pesticides exposure, the study aimed to determine the OP pesticides exposure in Southern Indian men with idiopathic abnormal semen analysis and find the possible source of their OP pesticides exposure.
In this cross-sectional pilot study, fifty men with idiopathic abnormal semen analysis as cases and fifty men with normal semen analysis as controls were recruited. Detailed history wastaken and general and systemic examinations were carried out. OP pesticides exposure was determined by assessment of pseudocholinesterase and acetylcholinesterase levels and urinary OP pesticides metabolites dialposure as compared to men with a normal semen analysis.
Southern Indian men with idiopathic abnormal semen analysis had a significantly higher percentage of OP pesticides exposure as compared to men with a normal semen analysis.
Cisplatin (CIS) is an effective antineoplas tic drug that is used to treat various types of cancers. However, it causes side effects on the male reproductive sys tem. The present s tudy aimed to inves tigate the possible protective effects of
(AL) gel (known as an antioxidant plant) on CIS-induced changes in rat sperm parameters, tes ticular s tructure, and oxidative s tress markers.
In this experimental study, forty-eight adult male rats were divided into 6 groups including control, CIS, AL, metformin (MET), CIS+AL, and CIS+MET. CIS was used intraperitoneally at a dose of 5 mg/kg on days 7, 14, 21, and 28 of the experiment. AL gel (400 mg/kg per day) and MET (200 mg/kg per day) were administered orally for 35 days (started one week before the beginning of the experiment). Testes weight and dimensions, and morphometrical and histological alterations, activities of antioxidant enzymes including superoxide dismutase (SOD) and glutathione peroxidase (GPx), serum testosterone concentration, lipid peroxidat against CIS-induced testicular alterations.
The results suggest that AL as a potential antioxidant plant and due to free radicals scavenging activities, has a protective effect against CIS-induced testicular alterations.
Gonadotropin-releasing hormone (GnRH) analogues have been extensively utilized in the ovarian stimulation cycle for suppression of endogenous rapid enhancement of luteinizing hormone (LH surge). Exclusive properties and functional mechanisms of GnRH analogues in
fertilization (IVF) cycles are clearly described. Isoprenaline This study was performed to evaluate clinical and molecular impacts of the GnRH agonist and antagonist protocols in IVF cycles. For this purpose, gene expression of cumulus cells (CCs) as well as clinical and embryological parameters were evaluated and compared between two groups (GnRH agonist and antagonist) during the IVF cycle.
Twenty-one infertile individuals were enrolled in this study. Subjects were randomly allocated into two groups of GnRH agonist (n=10) treated patients and GnRH antagonist (n=11) treated individuals. The defined clinical embryological parameters were compared between the two groups. Expression of
and
genes were assessed in the CCs of the participants using the reapment, and clinical outcomes between the group treated with GnRH agonist and the one treated with antagonist protocol, the GnRH antagonist protocol was slightly more favorable. However, further clinical studies using molecular assessments are required to elucidate this controversial subject.
Polycystic ovary syndrome (PCOS) is considered to be one of the most common endocrine disorders in women of reproductive age. Zinc, a vital trace element in the body, plays a key role in maintaining health, especially due to its antioxidant role. On the other hand, lack of antioxidants and oxidative stress can adversely affect oocytes quality and consequently fertility rate. The available studiesthat report the effect of follicular fluid (FF) zinc in terms of the number and quality of the oocytes in infertile women with PCOS, are few and not consistent. We decided to investigate this issue.
In this cross-sectional study, from the women with PCOS referring to Omolbanin Hospital, Dezful, Iran (February to December 2019), a total of 90 samples (follicular fluid, oocytes, and embryos) were collected from those who had undergone
fertilization (IVF). To measure zinc level in follicular fluid, high performance liquid chromatograpy (HPLC) was utilized. Also, oocytes maturity and embryos quality evaluation was os.
Infertility stigma is a phenomenon associated with various psychological and social tensions especially for women. The stigma is associated with a feeling of shame and secrecy. The present study was aimed to explore the concept of infertility stigma based on the experiences and perceptions of infertile women.
This qualitative conventional content analysis study was conducted in Isfahan Fertility and Infertility Center, Iran. Data were collected through in-depth interviews with 17 women who had primary infertility. All the interviews were recorded, transcribed and analyzed according to the steps suggested by Graneheim and Lundman. The standards for Reporting Qualitative Research (SRQR) checklist was followed for this research.
Eight hundred thirty-six initial codes were extracted from the interviews and divided into 25 sub-categories, 10 categories, and four themes. The themes included "stigma profile, self-stigma, defensive mechanism and balancing". stigma profile was perceived in the form of verbal, social and same sex stigma. Self-stigma was experienced as negative feelings and devaluation. Defensive mechanism was formed from three categories of escaping from the stigma, acceptance and infertility behind the mask. Two categories; empowered women and pressure levers, created a balancing theme against the infertility stigma.
Infertile women face social and self-stigma which threatenstheir psychosocial wellbeing and self-esteem. They use defensive response mechanisms and social support to mitigate these effects. Education focused on coping strategies might be helpful against infertility stigma.

Premature ovarian failure (POF) can be found in 1% of women at the age of 35-40, mostly due to unknown causes. PI3K-Akt signaling is associated with both ovarian function and growth of primordial follicles. In this study, we examined the effects of autologous
ovarian activation with stem cells and autologous growth factors on reproductive and endocrine function in patients with ovarian impairment.
The longitudinal prospective observational study included 50 patients (between 30 and 50 years) with a diagnosis of POF and infertility. This multicenter study was performed at Jevremova Special Hospital in Belgrade, Saint James Hospital (Malta), and Remedica Skoplje Hospital, between 2015 and 2018. All patients went through numerous laboratory testings, including hormonal status. The autologous bone marrow mesenchymal stem cells (BMSCs) and growth factors were used in combination for activation of ovarian tissue before its re-transplantation. The software package SPSS 20.0 was used for statistical analysis oelaying menopause, thus improving the quality of life and general health (Registration number NCT04009473).
Prior to chemotherapy interventions,
i maturation (IVM) of folliclesthrough vitrification can be used to help young people conserve their fertility. The aim of s tudy was to inves tigate effect of sodium alginat scaffold on follicles development and improvement of the culture medium.
This experimental study was conducted on immature female BALB/c mice (12-14 days). Follicles were gathered mechanically and placed in α-Minimal Essential Medium (α-MEM) containing 5% fetal bovine serum (FBS). Some pre-antral follicles were frozen. The fresh and vitrified follicles were cultured in different concentrations of sodium alginate (0.25%, 0.5%, and 1%) and two dimensional (2D) medium for 12 days. The samples were evaluated for viability percentage, the number of MII-phase oocytes and reactive oxygen specious (ROS) level. Additionally,
and
gene expressions were assessed in the samples.
The highest and lowest percentages of follicle viability and maturation in the fresh and vitrified groups were respectivelyy compensated using a three dimensional (3D) cell culture medium.
Alginate hydrogel at a proper concentration of 5%, not only helps follicle get mature, but also promotes the expression of developmental genes and reducesthe level of intracellular ROS. Follicular vitrification decreases quality of the follicles, which are partially compensated using a three dimensional (3D) cell culture medium.Semen analysis is usually the first step in the assessment of male fertility. Although analyzes provide valuable information about male fertility, success of cytoplasmic sperm injection using this method is not predictable. In the recent years, studies have shown that sperm quality assessment helps clinicians predict male fertility status based on the expression of biomarkers. To write this article, a comprehensive study was conducted on several RNA transcripts by searching related words on medical information databases by 2018. According to the literature, spermatogenesis based disorders in male infertility have a significant relationship with the expression level of some RNA molecules (like DAZ and PRM1/PRM2 ratio) in semen and testicular tissue. Thus, they might be used as predictor biomarkersto evaluate success rate of testicular sperm extraction (TESE) procedure, but confirmation of this hypothesis requires more extensive research. By comparing the number of RNAs attributed to each fertility disorder in men, it is possible to trace the causes of disease or return fertility to some infertile patients by regulating the mentioned molecules.
