Original practice preview

These are current-syllabus NeetVellum questions, shown separately from historical-paper provenance.

Example 1 · difficulty 2/5

Compared with a non-medicated device such as the Lippes loop, a copper-releasing IUD like CuT offers added protection chiefly because the released copper ions:

A. suppress FSH secretion and thereby prevent ovulation
B. suppress sperm motility and the fertilising capacity of sperms
C. permanently thicken the cervical mucus plug
D. dissolve the zona pellucida surrounding the released ovum

Example 2 · difficulty 2/5

A nursing mother wishes to rely solely on lactational amenorrhoea for spacing her next child. This natural method will protect her from conception only when:

A. she breast-feeds the infant fully up to six months and her menstrual cycles have not resumed
B. she continues partial breast-feeding along with top feeds until the child is one year old
C. menstrual bleeding has stopped, regardless of how long the feeding continues
D. the infant receives cow's milk supplements during the very first month of life

Example 3 · difficulty 1/5

Which statement correctly distinguishes tubectomy from vasectomy?

A. Tubectomy blocks the vasa deferentia whereas vasectomy blocks the oviducts
B. Both procedures are performed through an incision made in the scrotum
C. Tubectomy halts gamete formation, while vasectomy only blocks gamete transport
D. In tubectomy a small portion of the fallopian tubes is cut and tied, whereas in vasectomy the same is done to the vasa deferentia

Frequently asked questions

Are these official NEET 2019 Biology Reproduction PYQs?

No. The previews are original NeetVellum practice questions. A historical item receives a PYQ label only after its official paper and authoritative final answer key are attached. Use the official archive for the source paper.

How should I use the NEET 2019 paper?

Solve the official paper under its original timing, verify against the final key, classify every miss, and then use the linked current-syllabus practice bank to repair the exposed concept.
