All of the following statements are true except :

Ans. is d i.e. Oxytocin is used for inducing aboion in Ist trimester Lets see each option one by one. Oxytocin causes contraction of smooth muscles of uterus. The sensitivity of uterine musculature to oxytocin is enhanced by estrogen and inhibited by progesterone. The sensitivity of uterus to oxytocin becomes very much increased in late pregnancy. Oxytocin levels reach maximum at the time of bih (i.e. option "a' is correct). In lactating women genital stimulation enhances oxytocin release (option "c" is correct). Prostaglandins are used in I. and Ilna trimester for induction of aboion. I can not understand what the examiner wants to say by "Ur trirnc,ctPr aboion" as beyond 28 weeks fetus is ble therefore, term aboion is never used. It may be a printing mistake. As far as option "d" is concerned -- It is absolutely incorrect as oxytocin is never used for Is' trimester aboions. Friends don't get upset, if you don't remember "methods used of inducing aboion"right now, as we have dealt with it in detail in chapter Aboion & MTP".
