Background: Retinoids have been suggested to play a role in oogenesis and oocyte survival. Objective: In the present study the effects of retinol palmitate were investigated on differential follicular counts in response to superovulation as well as follicle quality after vitrification of ovaries. Materials and Methods: Ten, 4 week old female BALB/c mice were randomly assigned to either paraffin (n=5) or retinol palmitate (n=5) administration. Vitamin A administered animals received (i.p.) 250 IU retinol palmitate, dissolved in 0.1 ml of paraffin oil on days one and ten followed by superovulation with 10 IU PMSG. Paraffin administered mice were only treated with 0.1 ml of paraffin oil. The collected left ovaries from both paraffin and vitamin A administered groups were considered as non-vitrified and the collected right ovaries from both treated groups underwent vitrification. Ovaries in the vitrified group were frozen sequentially by placing into two vitrification solutions {VS1: 10% ethylene glycol (EG), 10% DMSO in holding medium (TCM-199 + 20% FBS: HM) and VS2: 20% EG, 20% DMSO in HM}. After warming, recovered ovaries as well as non-vitrified ovaries were serially sectioned and examined histopathologically. Results: The proportion of antral follicles in the non-vitrified ovaries from vitamin A administered mice was statistically higher than the non-vitrified ovaries from paraffin administered group (29.4% vs. 15.6%, respectively; p<0.001). No difference due to retinol palmitate injection was observed for the rate of small follicles between the two non-vitrified groups. The percentage of damaged follicles did not show any significant differences between the two vitrified groups (76% vs. 79%). Conclusions: Our results demonstrate that administration of retinol palmitate may improve the response to superovulation through the shift of follicular growth towards antral follicle development. However, no positive effect of retinol palmitate in the quality of follicles is probable when ovaries are vitrified.

Background: It is estimated that about 50% of causes of recurrent pregnancy loss (RPL) cases remain unknown. Sperm factors are suggested to have probable role in cases with RPL.
Objective: The goal was to determine the possible relationship between semen bacterial contaminations with unexplained RPL. Also, the correlation between number of bacterial colony and sperm chromatin condensation was examined.
Materials and Methods: This study consisted of 30 fertile men (group A) and 30 infertile (group B) patients with unknown RPL. Semen collection and analysis were done according to WHO manuals. Sperm count and motility were evaluated by Makler chamber. Eosin-Nigrosin and Papanicolaou staining methods were applied for viability and morphology assessment, respectively. The semen samples from both groups were cultured for aerobic bacteria. Aniline blue (AB) and toluidine blue (TB) staining methods were applied for evaluating sperm chromatin condensation.
Results: The numbers of colonies were significantly higher in group B when compared to group A. Also, S. aureus and E. coli showed significant differences between two groups. Both AB+ and TB+ sperm cells showed significant increase in group B compared to group A. There was a significant negative correlation between colony number and progressive motility (p=0.01), sperm viability (p=0.007). In addition, positive correlations were found between colony number and AB (p=0.001) and TB (p=0.004) as well.
Conclusion: Bacterial contaminations in semen of men from RPL couples had significantly higher levels when compared to fertile controls. Presence of microorganisms in semen may be correlated with irregular sperm parameters and quality.

Background: Regarding the close and continuous interaction of infertility staff with hopeless infertile couples and in the contrary the atmosphere of happiness especially in obstetric wards make a sense that considering anxiety and depression it would be a difference between these two wards.
Objective: The objective of this study is the comparison of the rate of depression and anxiety between the two wards of infertility and obstetrics and gynecology.
Materials and Methods: This study is a descriptive-correlation study based on cross-sectional method. 199 individuals who were the staff of infertility and obstetrics and gynecology wards in four provinces enrolled in this study through stratified sampling. Data collection was done by demographic questionnaire, Spiel Berger and Beck depression inventory tests. Data were analyzed by SPSS software using ANOVA test.
Results: The result showed the rate of anxiety in obstetrics and gynecology staff of Isfahan center (54.69±13.58) and depression rate had increased level in infertility staff of Shiraz center (14.94±10.87). Overall, there was significant correlation between anxiety, depression and work place (p=0.047, 0.008 respectively). According to ANOVA test, the mean value of anxiety level was higher in the staff of four obstetrics and gynecology centers and one infertility center
Conclusion: As long as we know that infertile couples have little chance for success rate and obstetrics and gynecology wards patients have little risk of failure in treatment, it could be mentioned that the anxiety and depression in the staff are not correlated with the client illness.

Background: Globozoospermia is a severe form of teratozoospermia (incidence < 0.1%) in infertile men that is characterized by round headed sperm and acrosomeless in semen.
Objective: To compare the semen parameters, protamine deficiency, and apoptosis in ejaculated spermatozoa between globozoospermic and normozoospermic men.
Materials and Methods: Thirty six semen samples were divided into two groups including 15 infertile men with total globozoospermic (> 90% round-headed sperm) and 21 healthy donors with normal spermograms as controls. Semen analysis was performed according to World Health Organization criteria (2010). Sperm protamine deficiency was assessed using Chromomycin A3 (CMA3) staining and the rate of apoptotic spermatozoa was evaluated with TUNEL assay.
Results: Sperm concentration, motility, and normal morphology in globozoospermic men were significantly decreased compared with controls (p<0.05). The rate of CMA3-reacted spermatozoa (CMA3+) in globozoospermic men was higher than controls (65.93 ± 11.77 vs. 21.24 ± 7.37, respectively, p<0.0001). The rate of apoptotic spermatozoa (TUNEL positive) were significantly increased in globozoospermic cases with respect to the controls (17.60 ± 10.72 and 5.95 ± 3.02, respectively, p<0.0001). There was no significant correlation between sperm protamine deficiency and apoptosis in globozoospermic men.
Conclusion: Globozoospermic samples contain a higher proportion of spermatozoa with abnormal chromatin packaging and DNA fragmentation than normozoospermic samples. Therefore, in addition to absence of acrosome in the spermatozoa of globozoospermic patients, the high percentage of spermatozoa with immature chromatin and apoptotic marker may be considered as the other etiologies of infertility in these patients.

Background: Methamphetamine (MA) was shown to have harmful effects on malereproductive system.
Objective: To investigate probable effects of daily administration of MA on spermparameters and chromatin/DNA integrity in mouse.
Material and Methods: Thirty-five NMRI male mice were divided into five groupsincluding low, medium, and high dosage groups which were injectedintraperitoneally with 4, 8 and 15 mg/kg/day for 35 days, respectively. Normalsaline was injected in sham group and no medications were used in control group.Then, the mice were killed and caudal epididymis of each animal was cut and placedin Ham’s F10 medium for sperm retrieval. To evaluate sperm chromatinabnormalities, the aniline blue, toluidine blue and chromomycine A3 were used. Forsperm DNA integrity and apoptosis, the acridine orange, sperm chromatindispersion, and TUNEL assay were applied. For sperm morphology, Papanicolaoustaining was done
Results: Normal morphology and progressive motility of spermatozoa decreased inmedium and high dosage groups in comparison with the control group (p=0.035).There was a significant increase in rate of aniline blue, toluidine blue, andchromomycine A3 positive spermatozoa in high dosage group. In a similar manner,there was an increase in rates of acridine orange, TUNEL and sperm chromatindispersion positive sperm cells in high dosage group with respect to others.
Conclusion: MA abuse in a dose-dependent manner could have detrimental effectson male reproductive indices including sperm parameters and spermchromatin/DNA integrity in mice

Background: Asthenozoospermia is one of the etiologies for male factor infertility. It was shown that any abnormality in protamines genes, reduction of protamines transcript and protamines deficiency may play a key role in asthenozoospermia.
Objective: The aim of the current study was the evaluation of protamine-1 and 2 genes (PRM1 and PRM2) polymorphisms in asthenozoospermic men. Materials and Methods: In this case-control study, the samples were corresponded to asthenozoospermic specimens of infertile men. The normozoospermic samples were considered as the control group. DNA sequence amplification was performed using four PRM1 and PRM2 primers, designed from 5chr('39') to 3chr('39') flank regions. The human PRM1 and PRM2 gene sequences were screened in search of potential mutations in highly prevalent polymorphism regions in asthenozoospermia versus normozoospermia.
Results: Totally, nine highly prevalent polymorphism regions between the forward and reverse primers were screened. Three of them corresponded to PRM1 and six to PRM2. The most prevalent polymorphism regions in PRM1 were related to 102G>T (rs35576928), 49C>T (rs140477029) and 139C>A (rs737008). In the PRM2, 6 highly prevalent polymorphisms regions were screened, including 248C>T (rs779337774), 401G>A (rs545828790), 288C>T (rs115686767), 288G>C (rs201933708), 373C>A (rs2070923), and 298G>C (rs1646022). The allele frequencies of three upper mentioned single nucleotide polymorphisms in asthenozoospermic men including 373C>A, 298G>C and 139C>A was higher than the control group.
Conclusion: Our findings indicated that the frequency of some altered genotypes in asthenozospermia was slightly higher than control group. We proposed more extensive studies to be sure that; these genotypes can precisely be related to diagnosis of asthenozoospermia, as the molecular markers.

Background: The etiological nature of preeclampsia is heterogeneous. The use of biomarkers indices in early pregnancy helps to have appropriate stratification of pregnancies into high- and low risk for the purpose of choosing timely interventions.
Objective: The aim of this systematic review was to determine the pathogenic role of soluble soluble fms-like tyrosine kinase-1 (sFlt-1) and placental growth factor (PlGF) inthe prediction of preeclampsia in women.
Materials and Methods: We performed a systematic search of the international databases including PubMed, Scopus, and Web of Science until August 2017. The quality of included studies was assessed using the Newcastle-Ottawa Scale. The primary outcome in this review was preeclampsia. The statistical heterogeneity was assessed using the X2 test and quantified by I2. Pooled effects size was obtained by random effects model. Subgroup  analyses were also carried out.
Results: Totally, 284 records were identified in the initial search and 15 records were finally included in the meta-analysis. The pooled odds ratios (ORs) for the association between the high level of sFlt-1 and low level of PlGF and subsequent development of preeclampsia among women were 5.20 (95% CI: 1.24–9.16) and 2.53 (95% CI: 1.33–3.75), respectively. The mean difference for sFlt-1 and PlGF in women with preeclampsia compared to controls was 1.15 (95% CI: 0.43–1.86) and –0.94 (95% CI: –1.37–0.52),respectively.
Conclusion: According to the results from this meta-analysis, increased levels of sFlt-1 and reduced levels of PlGF predict the subsequent development of preeclampsia.
