Back ground: Optimal IVF and embryo culture conditions depend on the composition of culture media being the most important determinants of successful in vitro interaction of the gametes and subsequent embryo development. ATP is fundamental factor to maintain the life, by providing energy, and controlling the cell function and metabolism. Objective: To investigate the effect ATP supplied to culture medium on fertilization rate and in mice as model for human being. Materials and Methods: The female mice (90) were superovulated using superovulation program (SOP) to produce large number of oocyte were divided into three groups, G1 inseminated with vassal sperm in vitro alone (control) , G2 inseminated with vassal sperm in vitro using SMART enriched with ATP(1.25mM). While, G3 inseminated with vassal sperm in vitro using SMART medium enriched with ATP (2.5mM). Mouse spermatozoa were collected from both vas deferens. Then sperm parameters were assessed after 30 min. IVF technique was performed for 3 groups. Results: The results of the present study appear, significantly increment (P<0.05) in the IVF (%) was observed when using 2.5 mM ATP as compared to 1.25 mM ATP and control group. Conclusions: The result showed that addition of high ATP concentration (2.5 mM) enriched to the culture medium improved percentage of in vitro fertilization.
Background: Polycystic ovary syndrome (PCOS) is the most common cause of hyperandrogenism anovulatory infertility; it affects 510-% of females in the reproductive age. PCOS is a risk disease; it has an association with gynecological malignancy. Objectives: To determine whether Cancer Antigen 125 (CA125) and Cancer Antigen 153-(CA153-) levels are increased in PCOS and possibility of CA125 and CA153- to be used as a diagnostic marker of PCOS. Methods: Seventyfemales with PCOS diagnosed depending on threecriteria: Menstrualhistoryofoligomenorrhea ultrasound examinations revealed polycystic ovaries and biochemical hyperandrogenism. Twenty normal fertile females serve as control group. Blood samples were obtained from all individuals from 2nd-4th day of menstrual cycle to measure levels of FSH, LH and testosterone.Second blood samples were collected from the same patients during late follicular phase to measure CA153- and CA125( by ELISA). Results: Females with PCOS and controls differed significantly(p< 0.05) in total serum testosterone (p). Females with PCOS and controls have highly significant difference (p < 0.001) in LH mean level (7.881.83+ vs 3.900.73+) respectivelyand, highly significant difference (p < 0.001) in LH/FSH ratio and BMI parameters. No significant differences (p > 0.05) were found in FSH, CA125 and CA153- between PCOS patients and the controls.There were positive correlation between testosterone and CA125.Negative correlation between testosterone and CA153- serum values. Conclusion: There were no changes in the serum levels of CA125andCA153- in PCOS patient at the age of reproduction and those cancer antigens could not be used as diagnostic markers for polycystic ovarian syndrome.
Background: The evaluation of ovarian reserve has been, and still, the focus of substantial clinical research. The assessment of ovarian reserve is valuable for determining stimulation protocols, and because of limited predictive value of age alone, or other passive hormonal analysis in estimating response to the exogenous stimulation, Dynamic research was done on serum inhibin B. Objective: Measurement of serum inhibin B as a predictive evaluation of early ovarian response following ovulation induction program in intrauterine insemination(IUI). Materials and Methods: Thirty couples were involved in IUI program. They divided into two groups: group (1) 15 women were treated by Gonadotropin(Gn) recombinant follicle -stimulating hormone (rFSH). While group (2), 15 women were treated by Clomiphene citrate (CC). Treatment started at day 3 of the menstrual cycle. Serial hormonal profile tests namely; Inhibin B, Estradiol (E2), Follicle-stimulating hormone (FSH), Luteinizing hormone (LH) were done at days 3, 7 of the menstrual cycle and the day of human chorionic gonadotropin hormone (hCG) injection with recurrent ultrasonography (US) to confirm the number and development of the follicles. Results: There was a significant difference in the level of inhibin B (P< 0.05) between day 3 and 7 of the cycle with the mean of the follicle number 1.67±0.18 in group(1), while in group (2) there was a non significant difference (P>0.05) in the level of inhibin B between day 3 and 7 of the cycle with the mean of the follicle number 2.14±0.17. Percentage of pregnancy rate in IUI in this study was 19.23%. Percentage of pregnancy rate in group (1) was 25%,while in group (2) was 14.28%,but there is a significant difference (P<0.05) in the pregnancy rate between the two groups. Conclusion: It was concluded that serum inhibin B obtained at day 7(day 5 of (Gn) therapy) offers an early and accurate prediction of ovarian response to (Gn) stimulation while there was no significant change in the level of inhibin B between day 3 and 7 of the cycle in patients treated by CC.
Background : progesterone used as a therapeutic agent in human pregnancy. The sufficient evidence to hypothesize that progesterone may have teratogeniceffect on the reproductive system of female offspring. Objectives: This study was established to explore the individual impact of differ ent doses of progesterone during intrauterine period on reproductive system of female mouse, and on some reproductive parameters. Materials and Methods: ninety adult female mice (8-10 weeks) and weight (25-28) gm divided into three groups. Control group (G1) was treated daily (IM) injection with sesame seed oilfrom 1-14 day of pregnancy, and other two groups that treated with different doses of progesterone G2 (0.4mg/kg. B.wt/day), G3 (0.8mg/kg. B.wt/day), daily (IM) injection of progesterone from 1-14 day of pregnancy then selecting of Female offspring and sacrificed at age zero day, one month, two month. Parameter analysis involvedanogenital distance , body and ovary weights, , length of epithelial cells, number and diameter of follicles (Primordial , Primary , Secondary and Mature antral) , corpus luteum and using histological section by (motic image plus) and hormonal assay including proges terone and Estrogen. Results: The results of this study demonstrated that at one month, two months after birth, there was a highly significant increase P< 0.01 in theanogenital dis tance . The statistical analysisshowed no statistical significant difference in the body and ovary weights , at one month after birth, The statistical analysisshowed highly statistically significant decreased(P< 0.01 ) in both G2 and G3 in the number of follicles . At one,two months after birth, there was a highly significant decreased (P< 0.01 ) in both G2 and G3 in the number ofcorpora lutea. At age two month, there was a highly significant decreased (P< 0.01 ) in both G2 and G3 in the height of epithelial cell layer.There was a highly significant decreased (P< 0.01 ) in both G2 and G3 in the diameter of follicles (Primordial , Primary , Secondary and Mature antral) follicles . There was a highly significant decreased (P< 0.01 ) in both G2 and G3 in Estrogen and Progesterone levelof female off spring when compared with the control group G1. Conclusion: The results showed higher doses of progesterone for long period in pregnancy can impact some reproductive parameters of female offspring mice.

Background: Male obesity is associated with physiological changes that can negatively affect male fertility. Obese men have demonstrated a 3-fold increase in the prevalence of oligozoospermia when compared with men with normal Body Mass Index (BMI). Objective: To find the correlation between Aromatase enzyme with the following hormones (follicle stimulating hormone(FSH), Luteinizing hormone(LH), Estradiol(E2), and testosterone) in the obese infertile male. Subjects, Materials and Methods: Seventy obese infertile male (patients) and twenty obese fertile male (control) are enrolled in this study. Aromatase enzyme, FSH, LH, E2 and testosterone hormones were measured in their serum. All serum samples were measured by ELISA method. Results: Median human cytochrome enzyme level was significantly higher in patients than in control group, 87.55+ 12.48 pg./ml versus 56.95+9.88 pg./ml, P= 0.014. In patients group, a significant positive correlation was found between human cytochrome enzyme, FSH, and LH. Conclusions: The present study showed clearly that male obesity negatively affects fertility through changes in hormone levels. The results suggest that increased estrogen because of aromatization in the fatty tissue, reflected through the increase in human cytochrome enzyme (aromatase), may be an important mechanism for the hypoandrogenemia and altered sperm parameters.
Background: Semen quality is a measure of the ability of semen to accomplish fertilization. Semen quality involves both sperm quantity and quality. The general population is exposed to metals at low concentrations either voluntarily through supplementation or involuntarily through intake of contaminated food and water or contact with contaminated soil, dust, or air. Some metals, such as lead (Pb), are nonessential xenobiotics that can be measured in most of the general population. Objectives: Our goal in this study is to assess relationships between exposure to lead at environmental levels and human semen-quality parameters. Materials and Methods: The study populations consist of 81 infertile male of general population who are occupationally unexposed to lead and another 26 healthy fertile male as control group. Blood lead and seminal plasma lead measurements performed by the electrothermal-atomic absorption spectrometry (AAS) method. Macroscopic and microscopic examination of semen performed according to WHO recommendations. Seminal plasma separated from the spermatozoa by centrifugation and stored at -20°C until required for analyses. Results: This study showed significant increase in seminal plasma lead mean value in moderate and severe oligozoospermic infertile males than in fertile male controls( p<0.05). The result also showed no statistically significant difference in blood lead concentration among the infertile group compared to fertile controls. Conclusions: The results of this study indicate that even moderate exposure to Pb at environmental level (blood Pb < 400 µg/L) can significantly reduce reproductive capacity in men.
Background: Male obesity is associated with physiological changes that can negatively affect male fertility. Obese men have demonstrated a 3-fold increase in the prevalence of oligozoospermia when compared with men with normal Body Mass Index (BMI). Objective: To estimate the role of aromatase enzyme in decreasing sperm parameters in obese infertile men. Subjects, Materials and Methods: Seventy obese infertile male (patients) and twenty obese fertile male (control) are enrolled in this study. Seminal fluid analysis done according to criteria of WHO (2010). Results: A significant negative correlation was found between human cytochrome enzyme and sperm concentration, progressively motile sperm, non-progressively motile sperm, immotile sperm and normal morphology. Conclusion: The present study showed clearly that male obesity negatively impacts fertility through direct association between increased (BMI) and semen parameters. The results suggest that increased estrogen as a result of aromatization in the fatty tissue, reflected through the increase in human cytochrome enzyme (aromatase), may be an important mechanism for the hypoandrogenemia and altered sperm parameters.
Background: The effects of Lead and other essential metal like zinc and copper on the reproductive system have been previously reviewed. Objective: Our goal in this study was to estimate the levels of Lead, Zinc and Copper in patients with polycystic ovary syndrome and to confirm the effect of such metals on the female reproductive system at environmental exposure. Materials and Method: Fifty two women in their reproductive age (20-40) years old, which had been diagnosed as PCOS. Venous blood sample were taken from each patient and control, blood lead, zinc and copper were determined by atomic absorption spectrophotometer. Hormone assay were determined by ELISA (Enzyme Linked Immune Sorbet Assay) technique. Results: This study showed a significant increase of blood lead and serum zinc, copper (p<0.01), in addition to testosterone, lutenizing hormone, LH/FSH ratio and body mass index (BMI) (p<0.05) in patients with polycystic ovary syndrome when compared with control. Conclusions: On the basis of the observations of the present study, it can conclude that the increased levels of Lead as a result of the exposure to this metal may be a risk factor for the development of polycystic ovary syndrome in women and has adverse effects on female endocrine and reproductive function.
