Abstract

The present study aimed to determine the effects of the different stages of pregnancy and fetus genderon Estrogen , Progesterone, Testosterone , TSH , T3 and T4 hormones during the pregnancy. This study took place on (90) pregnant women in different stages of pregnancy and determine each stage three months pregnancy , women's ages ranged between (40-15) years , was withdrawn 5mlof bloodfrom pregnant women were then separated the serum ,to measuredthe concentrations of hormones using a number of measurement of kitsto each hormone .The results shown signigicant effect (P <0.05) in estrogen in the first and the third temisterscompared with the intermediatetemister . significant decrease (P <0.05) in the effect of progesterone in the firsttemister, compared with the second and thirdtemisters. Did not notice any significant differences of testosterone among other temisters of pregnancy. Outweigh the high (P <0.05) in the effect of the hormone TSH in the first temister and the second compared to the third temister. Significant decrease (P <0.05) in the effect of T3 in the second and third temisters compared with the first temister. Significant decrease P <0.05)) in effect T4 in the second phase compared with the first and third temisters. Female fetus significantly (P <0.05) in the effect of estrogen in the first temister, compared with the male sex in the third stage. Female fetus significantly (P <0.05) in the effect of progesterone in the first temister and the third compared with the male fetus. The male fetus significantly (P <0.05) in the effect of testosterone in the second and third temisters compared with the female fetus. And found significant (P <0.05) in the effect of TSH in the first temisterin the female fetus when compared with the male fetus. Significant (P <0.05) in the effect of T3 in the male fetus compared with the female fetus at all temisters. Significant (P <0.05) in the effect of T4 in the male fetus compared with the female fetus in the first and secondtemisters
