-
Vaginal cytology
-
Vaginal constriction
-
Vaginal biopsy

-
Voice deepens
-
Menstruation starts
-
Breast size increases
B
Correct answer

-
menstruation
-
gestation
-
ovulation
-
fertilization
A
Correct answer

Menstruation is the monthly shedding of the uterine lining (endometrium) accompanied by blood flow, occurring when fertilization doesn't happen. Gestation is pregnancy duration, ovulation is egg release, and fertilization is the fusion of egg and sperm.
-
hormonal
-
protein
-
enzyme
-
fat
A
Correct answer

Chemical contraceptives like birth control pills work by altering the body's hormonal balance, specifically preventing ovulation by maintaining constant levels of estrogen and progesterone. This mimics pregnancy and stops the release of eggs.
-
uterus
-
ureter
-
vagina
-
ovary
A
Correct answer
Explanation
Menstruation is the shedding of the endometrium (inner lining) of the uterus when fertilization does not occur. The ureter carries urine, vagina is the birth canal, and ovary produces eggs but has no lining to shed.
-
mechanical methods
-
surgical methods
-
hormonal methods
-
all of these
A
Correct answer
Explanation
Mechanical barrier methods like condoms physically prevent sperm from entering the female reproductive tract. Surgical methods (sterilization) and hormonal methods (preventing ovulation) work through different mechanisms and don't primarily prevent sperm entry itself.
-
Oviduct
-
Vagina
-
Uterus
-
Ovary
B
Correct answer
Explanation
The vagina is the female reproductive organ that receives the penis during sexual intercourse and serves as the birth canal. The oviduct (fallopian tube) is where fertilization occurs, the uterus houses the developing fetus, and the ovary produces eggs. The vagina's muscular walls facilitate both intercourse and parturition.
-
During puberty
-
During menopause
-
During labour pain
-
After menopause
A

-
Oral contraceptive pills
-
Mechanical barriers
-
Surgical methods
-
All of the above
D
Correct answer
Explanation
All three methods - oral contraceptive pills, mechanical barriers like condoms, and surgical methods like sterilization - are valid contraceptive measures for family planning. Different methods suit different needs based on effectiveness, reversibility, cost, and health considerations. Family planning programs offer multiple options to accommodate various circumstances and preferences.
