Abstract

Background: Physalis alkekengi (P. alkekengi)has been used as an abortive plant in Iranian traditional medicine for many years.
Objective: To investigate the effects of P.alkekengi on the fertility rate in female rats.
Material and Methods: In this experimental study, 40 female albino rats were divided randomly into two groups; group 1/for investigating the implantation sites and group 2/ for investigating the number and weight of neonates. In both groups, treated animals received plant extract at dose of 150 mg/kg on days 1-5 of pregnancy. In group 1, treated animals were euthanized at 7th days of pregnancy and number of implantation sites were counted. In group 2, treated animals maintained till delivery time and after delivery, the number and weight of neonates were investigated.
Results: Data showed that administration of P. alkekengi extract on days 1-5 of pregnancy significantly decreased the number of implantation sites, number and weight of neonates.
Conclusion: These results suggest that the extract produced anti- fertility effect probably by inhibiting implantation.

Abstract

Background: The task force on plants for fertility regulation in men continued with its program to identify novel prototypes in plants alleged to have fertility regulating properties. Nigella Sativa  seeds are frequently used in folk medicine in the Middle East and some Asian countries for the promotion of good health and treatment of many ailments.
Objective: To evaluated the role of alcoholic extract of Nigella sativa on fertility potential, Pituitary-testicular axis hormones and Testosterone in male rats.  
Materials and Methods: 24 male rats were randomly divided into 3 groups; control, group A and group B, each group comprising of 8 rats. Animals in control group received 1 ml of normal saline and treatment groups (A and B) received (gavage) graded doses of 200 and 400 mg/kg body weight of alcoholic extract of Nigella sativa seeds on a daily basis for 60 days. At the end of treatment period, fertility parameters such as body and reproductive organs weight, sperm motility, viability and count, epididymal sperm reserve (ESR), daily sperm production (DSP), blood testosterone concentration, Gonadotropins levels and fertility index were measured.
Results: There was a significant difference in testes and epididymidis weight, sperm count, ESR, DSP, blood testosterone concentration, LH and fertility index in both the lower dose group and the higher group as compared to the control group.
Conclusion: The results of this study showed that alcoholic extract of Nigella sativa seed especially in higher doses could increase fertility potential, LH and testosterone concentration in male rats.

Abstract

Background: Cryopreservation of ovarian tissues and pre-antral follicles is a promising prospect for preservation of women fertility.
Objective: The aim of this study was to evaluate the in vitro developmental competence of mouse vitrified pre-antral follicles in comparison to isolated pre-antral follicles derived from vitrified ovaries in the presence of alpha lipoic acid (ALA).
Materials and Methods: Pre-antral follicles derived from fresh, vitrified-warmed ovarian tissues and vitrified–warmed pre-antral follicles were cultured individually with or without ALA, followed by adding hCG to induce ovulation. The follicle growth, oocyte maturation, and embryo development were assessed.
Results: The diameter and development of follicles, oocyte maturation and embryo development rates were significantly higher in ALA supplemented groups compared to the respective ALA-free conditions groups. Aforementioned parameters were significantly higher in vitrified-warmed follicles in comparison to follicles derived from vitrified-warmed ovaries.
Conclusion: These findings support a superior performance of pre-antral follicles when vitrified rather than when isolated from vitrified ovaries with regard to increasing the rates of developmental parameters. Moreover, ALA improves the in vitro maturation of pre-antral follicles in vitrified and non-vitrified samples.

Abstract

Background: Infertility is defined as the inability to achieve the pregnancy within a year of unprotected intercourse. Infertility is a complex issue and different factors such as stress oxidative can be involved in this problem. So, any attempt to neutralize oxidative stress would be helpful in the treatment of infertility. Melatonin is a known scavenger of free radicals.
Objective: The aim of our study was to evaluate the level of melatonin and its correlation with oxidative biomarkers in fertile and infertile women.
Materials and Methods: The participants including fertile and infertile women were divided into two groups of 30 people. Blood sampling was performed and sera were collected. The level of Malondialdehyde (MDA), total antioxidant capacity (TAC) and melatonin were detected. Data were analyzed using T-test and their correlation was assessed using Spearman test.
Results: Serum melatonin from fertile women was higher than infertile women but the difference was not significant (p= 0.46). MDA level in fertile women was significantly lower than infertile women (p<0.001) and the level of TAC in fertile women was significantly higher than infertile women (p<0.001). Spearman test revealed a significant and direct correlation between melatonin and TAC in fertile and infertile women and a significant but reverse correlation between melatonin and MDA in infertile and fertile women.
Conclusion: Differences in the level of oxidative stress biomarkers in fertile and infertile individuals have been reported. This study revealed a significant correlation between melatonin and oxidative stress biomarkers, concluding that melatonin level could be involved in infertility.

Abstract

Background: Oxidative stress in reproductive system leads to sperm DNA damage and sperm membrane lipid peroxidation and may play an important role in the pathogenesis of male infertility, especially in idiopathic cases. Antioxidants such as carotenoids function against free radical damages. Objective : The aim of this study was to determine the levels of lycopene, beta-carotene and retinol in serum and their relationship with sperm DNA damage and lipid peroxidation in infertile and normospermic males. Materials and Methods: Sixty two infertile men and 71 normospermic men participated in this study. Blood and semen samples were collected from all subjects. Sperm DNA damage was measured using TUNEL method. Carotenoids, retinol, and malonedildehyde in serum were also determined. Results: DNA fragmentation was higher in infertile group comparing to control group. Serum levels of lycopene, beta-carotene and, vitamin A in infertile men were significantly lower than normospermic men (p< 0.001, =0.005, and =0.003 respectively). While serum MDA was not significantly different between two groups, MDA in seminal plasma of infertile men was significantly higher than control group (p< 0.001). Conclusion: We concluded that lycopene, beta-carotene, and retinol can reduce sperm DNA fragmentation and lipid peroxidation through their antioxidant effect. Therefore the DNA fragmentation assay and determination of antioxidants factors such as lycopene, beta-carotene and retinol, along with sperm analysis can be useful in diagnosis and treatment of men with idiopathic infertility.

Abstract

Background: Asparagus is a plant with high nutritional, pharmaceutical, and industrial values.
Objective: The present study aimed to evaluate the effect of aqueous extract of asparagus roots on the hypothalamic-pituitary-gonadal axis hormones and oogenesis in female rats.
Materials and Methods: In this experimental study, 40 adult female Wistar rats were divided into five groups, which consist 8 rats. Groups included control, sham and three experimental groups receiving different doses (100, 200, 400 mg/kg/bw) of aqueous extract of asparagus roots. All dosages were administered orally for 28 days.  Blood samples were taken from rats to evaluate serum levels of Gonadotropin releasing hormone (GnRH), follicular stimulating hormone (FSH), Luteinal hormone (LH), estrogen, and progesterone hormones. The ovaries were removed, weighted, sectioned, and studied by light microscope.
Results: Dose-dependent aqueous extract of asparagus roots significantly increased serum levels of GnRH, FSH, LH, estrogen, and progestin hormones compared to control and sham groups. Increase in number of ovarian follicles and corpus luteum in groups treated with asparagus root extract was also observed (p<0.05).
Conclusion: Asparagus roots extract stimulates secretion of hypothalamic- pituitary- gonadal axis hormones. This also positively affects oogenesis in female rats.

Abstract

Background: One of the most major obstacles of ovarian tissue vitrification is suboptimal developmental competence of follicles. Matrix metalloproteinases 2 (MMP-2) and 9 (MMP-9) and their tissue inhibitors TIMP-1 and TIMP-2 are involved in the remodeling of the extracellular matrix in the ovaries.
Objective: This study aimed to evaluate the expression of MMP-2, MMP-9, TIMP-1, and TIMP-2 genes in the preantral follicles derived from vitrified mouse ovaries.
Materials and Methods: In this experimental study, the gene expression of MMP-2, MMP-9, TIMP-1, and TIMP-2 in the isolated preantral follicles derived from fresh and vitrified ovaries of 14-16 days old female mice through real time qRT-PCR was evaluated. Developmental parameters, including survival rate, growth, antrum formation and metaphase II oocytes were also analyzed.
Results: The developmental parameters of fresh preantral follicles were significantly higher than vitrified preantral follicles. The TIMP-1 and MMP-9 expression levels showed no differences between fresh and vitrified preantral follicles (p=0.22, p=0.11 respectively). By contrast, TIMP-2 expression significantly decreased (p=0.00) and MMP-2 expression increased significantly (p=0.00) in vitrified preantral follicles compared with to fresh ones.
Conclusion: Changes in expression of MMP-2 and TIMP-2 after ovarian tissues vitrification is partially correlated with decrease in follicle development.

Abstract

Background: Preterm birth is the major cause of neonatal mortality and morbidity.
Objective: The aim of this study was to evaluate the effect of prophylactic vaginal progesterone on decreasing preterm birth rate and neonatal complications in a high-risk population.
Materials and Methods: A randomized, double-blind, placebo-controlled study was performed on 100 high-risk singleton pregnancies. Vaginal suppository progesterone (400 mg) or placebo was administered daily between 16-22 wks to 36 wks of gestation. Progesterone (n=50) and placebo (n=50) groups were compared for incidence of preterm delivery and neonatal complications.
Results: The preterm birth rate was 52%. Preterm birth rate before the 37 wks of gestation (68% vs. 36%: RR=1.89, 95% CI: 1.25-2.86) and also before the 34 wks of gestation (42% vs. 18%: RR=2.33, 95% CI: 1.19-4.58) in placebo group was significantly higher than progesterone group. Our study also showed that the administration of vaginal progesterone was associated with a significant reduction in the risk of birth weight ≤2500 gr, the rates of respiratory distress syndrome (RDS) and admission to the Neonatal Intensive Care Unit (NICU) in the progesterone group when compared with the placebo group. However, there was no significant difference between the two groups in terms of neonatal death, days of admission in NICU, intraventricular hemorrhage and necrotizing enterocolitis.
Conclusion: Prophylactic vaginal progesterone reduced the rate of preterm delivery, the risk of a birth weight ≤2500 gr, the rates of RDS and admission to NICU in women who were at risk of preterm delivery.

Abstract

Background: The uterus is a dynamic tissue responding to hormonal changes during reproductive cycles. As such, uterine stem cells have been studied in recent years. Transcription factors oct4 and sox2 are critical for effective maintenance of pluripotent cell identity. 
Objective: The present research evaluated the mRNA expression of oct4 and sox2 in the uterine tissues of ovariectomized mice treated with steroid hormones. 
Materials and Methods: In this experimental study, adult virgin female mice were ovariectomized and treated with estradiol 17β (E2), progesterone (P4), and a combination of E2 and P4 (E2 & P4) for 5 days. Uterine tissues were removed, and immunofluorescent (IF) staining and quantitative real-time PCR of oct4 and sox2 markers were performed. 
Results: IF showed oct4 and sox2 expression in the uterine endometrium and myometrium among all groups. The mRNA expression of oct4 (p=0.022) and sox2 (p=0.042) in the E2-treated group significantly were decreased compared to that in the control group. By contrast, the mRNA expression of oct4 and sox2 in the P4 (p=0.641 and 0.489 respectively) and E2 & P4-treated groups (p=0.267 and 0.264 respectively) did not show significant differences compared to the control group. 
Conclusion: The results indicate ovarian steroid hormones change the expression of oct4 and sox2 in the mice uterine tissues, which suggest the involvement of steroid hormonal regulation in uterine stem cells.

Abstract

Background: Diabetes has an adverse effect on spermatogenesis by rising oxidative stress.
Objective: The aim of this study was to investigate the effect of Teucrium Polium extract administration on spermatogenesis and testicular structure in diabetic rats induced with Streptozotocin.
Materials and Methods: 32 male Wistar rats were randomly divided into four groups (n=8/each): control group, diabetic group received distilled water, and two experimental groups included diabetic rats treated with 50 and 100 mg/body weigh of Teucrium Polium extract for 6 six weeks. After six weeks, the left testis had been removed and the morphometrical study was performed. Blood samples were collected from the ophthalmic veins of the rats and plasma levels of glucose and testosterone hormone were measured afterward.
Results: The reduction in diameters of the seminiferous tubules and thickening ofthe wall of the seminiferous tubules (p=0.05) were seen in diabetic rats. Also, thedegenerative changes in cells arrangement have been observed. Statistical analysisshowed the use of Teucrium Polium significantly improved the above disorders intreatment group (100 mg/BW) in contrast to the non treated diabetic group (p=0.05),but no significant difference was seen between the experimental group treated with50 mg/BW of Teucrium polium and diabetic group (p=0.08). These data alsorevealed that treatment of diabetic rats with 100 mg/BW of Teucrium Polium extractsignificantly improves the change in serum glucose (p=0.001) and testosterone(p=0.03).
Conclusion: The results of the present study indicate that diabetes produces degenerative changes in the testis of rats and administration of Teucrium polium reduces complications resulted from diabetes.

Abstract

Background: Neopterin is a significant and sensitive marker in estimating the activity of cellular immune system. Oxidative stress plays a role in the etiology of male infertility. Increased reactive oxygen species is accompanied with increase in neopterin level. Hence neopterin may be involved in male infertility.
Objective: The objective of this case-control study was to determine neopterin level in idiopathic infertile and normospermic men; furthermore, to identify its relationship with oxidative stress markers including total oxidant, malondialdehyde, sperm DNA fragmentation, and total antioxidant capacity of seminal plasma.
Materials and Methods: Forty seven infertile and forty three normospermic males were selected according to WHO criteria. Their semen and blood samples were taken; subsequently, the levels of neopterin, total oxidant, total antioxidant, malondialdehyde, and sperm DNA fragmentation were measured.
Results: The levels of neopterin, total oxidant, and malondialdehyde in seminal plasma of infertile males were significantly higher than those of normospermic group (p=0.038, 0.018, and 0.028, respectively). Furthermore, sperm DNA fragmentation in infertile men was higher than that of control group (p<0.001). Moreover, total antioxidant capacity of seminal plasma in infertile males was significantly lower than that of normospermic subjects (p=0.002). No significant difference was observed in serum neopterin, total oxidant, and malondialdehyde between the infertile and normospermic groups.
Conclusion: The significant inverse correlation between seminal plasma neopterin and total antioxidant in the infertile males supports a possible role of neopterin in male infertility. Neopterin can be suggested as a marker in monitoring and diagnosis of idiopathic male infertility.

Abstract

Background: Cytomegalovirus (CMV) virus can hide in urinary genital tract cells and affect male infertility disorders.
Objective: To evaluate frequency of CMV in the semen samples of men with infertility problems referring to a in vitro fertilization (IVF) center in Kerman, Iran and its association with the parameters of semen.
Materials and Methods: In this case-control study, Real time polymerase chain reaction test was performed for detection of human cytomegalovirus in 100 fertile men compared to 100 infertile men referred to the IVF center of Afzalipour Hospital, Kerman, Iran.
Results: Out of 200 samples, 30 samples (15%) were positive for CMV DNA virus (23/100 men (23%) in case group and 7/100 men (7%) in the control group). Sperm counts and motility in the control group were more than the case group (p˂0.0001). There was a significant relationship between the prevalence of CMV infection and male infertility (p˂0.001).
Conclusion: Our finding showed that, prevalence of CMV infection was higher in infertile men compared to fertile men and CMV infection can be considered as an important part of male infertility. So; antiviral treatment of positive cases can be effective in improving sperm quality and successful IVF. The relationship between CMV infection in semen and infertility was obtained in previous studies and was confirmed by our study.

Abstract

Background: The failure to retrieve oocytes from mature ovarian follicles is referred to as empty follicle syndrome. There is no exact explanation to this problem and it cannot be predicted using ultrasound or serum hormonal levels. The underlying mechanism of
Empty follicle syndrome remains obscure.
Objective: In this study, the authors have investigated the relationship between the Beta-Human chorionic gonadotropin (𝛽HCG) levels in the follicular fluid with or without the oocyte in the follicles of patients undergoing Intracytoplasmic Sperm Injection.
Materials and Methods: Seventy-three infertile couples underwent standard long protocol induction ovulation for Intracytoplasmic sperm injection. On the day of oocyte retrieval, each patient had two samples; follicular fluid including 2–3 follicles with oocyte and follicular fluid including of 2–3 follicles without oocyte were collected in separate tubes. These follicles had similar shape and size. The Samples were transferred to a laboratory for measuring the 𝛽HCG level, after which the 𝛽HCG levels were compared to the follicles with and without the oocyte in each patient.
Results: In this study, the 𝛽HCG level of follicular fluid in the follicles containing oocyte was 18.20 (8.35–42.92) IU/L and in the follicles without the oocyte was 13.50 (5.45– 25.81) IU/L. Levels of 𝛽HCG in the follicular fluids containing the oocyte were higher than without oocytes, This difference was not statistically significant (p = 0.16).
Conclusion: It seems that the follicular fluid 𝛽HCG isn’t caused by empty follicle syndrome, and that dysfunctional folliculogenesis may be the cause of this syndrome.
