    These test papers are just awesome.due to these papers we really do best in exams.
    THANKS ALL THE TEAM MEMBERS OF THIS SITE.THANK U ALL!!!!!!!!!!!

  • ankusha

    I Thought during menopause the level of gonadotropic hormone decreases

    • nimish deovra

      ankusha you must remember that menopause has nothing to do gonadotropic hormone but it is because decreasing level of estrogen and menstrual blood do not clot beause of several anticogulants like (gp89) present in it..i think you might be confusing only in these two parts of mcq…

  • ankusha

    i have some doubts in que 10… can someone help me out????

    • lipsa dash

      10th question is absolutely correct nd quiet easy…during menstruation blood cannot easily clot cuz.in the blood, fibrinolysin is present which is an anticoagulant factor and helps in the control of coagulation of blood

    • subham deep

      menstrual fluid contains a proenzyme called PROFIBRINOLYSIN that is responsible for the non clotting character of menses…

  • Aniket Saha

    all correct!! phew. anyways nice set of questions!! logical thinking also comes into play!!

  • bhaskar soni

    the answer of que. no. 7 should be option B.

  • krishu

    is ques 7 single option correct?? a & b may also be the reason…. plz reply

    • mukul

      yewah.. i totally agree wd u…the answer should be second..as pregnancy ceases menstrual cycle….

      • ankusha

        no… actually that is the technical fact tht if there is no fertilization n pregnancy a female will have periods.. but they are asking the basic reason for non occurence of REGULAR MENSTRUAL CYCLE

    • Sayali

      i too agree wid u .it should be b only, tht’s the simple logic.

    • sri chandini

      The main reason for stopping menstrual cycle is production of progesterone ,which maintenance the endometrium .So that is the main reason . What u said r also correct but they happen due to increase in progesterone
