Note: If the male is highly stimulated, it is possible for him to leak a clear fluid prior to ejaculation. This is called pre-cum or pre-ejaculatory fluid. PRE-CUM may cause pregnancy.

TAKE NOTE OF THIS BOARD EXAM QUESTION: When will the uterus assume the retroverted position? What trimester of pregnancy? ANSWER: AT THE SECOND TRIMESTER OF PREGNANCY. * If the woman is pregnant in the first trimester, her uterus is still anteverted but her uterus is already enlarging. Moreover, the uterus already compresses the urinary bladder, leading to urinary frequency. In the second trimester, the urinary frequency will be gone because of the uterus’ new positioning.

Oxytocic - Stimulant, stimulates contraction (e.g. Syntocinon, Pitocin, Oxytocin, Methergine). 2.
