Background: It has been claimed that by using different washing methods, the sperms can be separated according to size, motility, density, chromosomal content and surface markings and charge. These methods also reduce sperm chromatin deficiencies and screen the sperms before applying in assisted reproduction techniques.
Objective: This study compared simple density gradient methods and a combined method with albumin density gradient and PureSperm separation (alb/PureSperm) for sex preselection by double fluorescence in situ hybridization (FISH) versus chromomycin A3 staining to determine chromatin integrity. Materials and Methods: 30 normal semen samples were prepared with PureSperm, albumin gradients and alb/PureSperm. All samples were then stained by FISH and chromomycin A3. The results were compared with SPSS 11.5 and the Kruskal-Wallis test.
Results: The proportion of X-bearing spermatozoa by PureSperm separation (47.58±5.67) and Y-bearing spermatozoa by albumin gradient (46.13±3.83) methods were slightly higher than in putative normal sperm samples (1:1), but there were no significant differences in the X- or Y- bearing spermatozoa counts among the three methods. Albumin gradient separation tended to underestimate abnormal spermatozoa compared to PureSperm and combined alb/PureSperm.
Conclusion: Routine separation methods slightly enriched X- or Y- bearing spermatozoa, but the differences were not significant for clinical purposes. The combined alb/PureSperm method had no advantages for assessing sex ratio or chromatin integrity compared to simpler gradient methods.

Background: In traditional medicine zingiber officinale used to regulate female menstural cycle and treat male infertility. Recent studies have suggested the possible role of ginger extract in improving the testicular damage of busulfan.
Objective: The aim of this study was to evaluate the effects of zingiber officinale on the sperm parameters, testosterone level and the volume of the testes and seminiferous tubules by stereological methods.
Materials and Methods: Fifty rats were divided into four groups. All the rats were given a single intraperitoneally injection of 5mg/kg busulfan solution. The first group was kept as busulfan control, while the other groups were orally administrated ginger extract in graded doses of 50, 100 and 150mg/kg b.wt, for 48 consecutive days. At the end, all animals were anesthetized and their testes and vas deference were removed, fixed, embedded, and stained. The volume of testes and seminiferous tubules were estimated by cavalieri methods.
Results: The result showed, that zingiber officinale increased the volumes of seminiferous tubule in 100mg/kg treated group compared to control group. Sperm count (706×105 and 682×105) and the level of testosterone (50.90 ng/mL and 54.10 ng/mL) enhanced in 100 mg/kg and 150 mg/kg treated groups compared to control group (p=0.00).
Conclusion: It seems that zingiber officinale stimulate male reproductive system in induce busulfan infertility.

Background: The interaction between follicular cells and oocyte leads to a change in gene expression involved in oocyte maturation processes.
Objective: The purpose of this study was to quantify the expression of more common genes involved in follicular growth and oocyte developmental competence.
Materials and Methods: In this experimental study, the expression of genes was evaluated with qRT-PCR assay in female BALB/c mice pups at 3-day of pre-pubertal and 8 week old virgin adult ovaries. The tissue was prepared by H&E staining for normal morphological appearance. The data were calculated with the 2-ΔCt formula and assessed using non-parametric two-tailed Mann-Whitney test. The p<0.05 was considered as significant.
Results: The data showed a significant increase in the level of Stra8 and GDF9 in adult compared with newborn mice ovaries (p=0.049). In contrast, a significant decrease in the level of Mvh, REC8, SCP1, SCP3, and ZP2 was observed in adult mice ovaries compared to those in the newborn mice ovaries (all p=0.049 except SCP1: p=0.046). There was no significant difference in the level of OCT4 and Cx37 expression between adult and newborn mice ovaries.
Conclusion: The modifications in gene expression patterns coordinate the follicular developmental processes. Furthermore, the findings showed higher expression level of premeiotic gene (Stra8) and lower level of meiotic entry markers (SCP1, SCP3, and REC8) in juvenile than newborn mouse ovaries.
