Document Summary
Module #14 reproductive system study guide (sections 14. 1 to 14. 41) By the end of this section, you should be able to: describe the fetal development of the male and female reproductive systems. Development of of each respective reproductive tract doesn"t begin immediately after fertilization. During the first six weeks of development, male/female embryos contain common gonads. These structures will eventually form testes or ovaries. There are two sets of primitive reproductive tracts the mseonephric or wolffian duct and the paramesonephric tract or. With the correct cues, these structures will form either the male or female reproductive tract. In the developing male embryo, at 6-7 weeks the presence of the y causes the indifferent gonads to develop into testes. At 7 weeks testicular cells begin to produce mullerian inhibiting hormone which causes the mullerian duct to regress. At 9 weeks, testicular cells begin to produce testosterone.
