Saheli: The Non-steroidal Oral Contraceptive Pill

Biology · Reproductive Health · NEET

Saheli is a non-steroidal oral contraceptive pill for females, taken only once a week. It has very few side effects and a high contraceptive value, which makes it special among pills. Memory hook: "Saheli = Sahi (correct) once-a-week, and it is NON-steroidal" — this one word "non-steroidal" is exactly what NEET loves to test.
Saheli vs Normal Oral Contraceptive PillSaheli• NON-steroidal preparation• Once a week pill• Very few side effects• High contraceptive valueNormal Pills• Steroidal (progestogen /progestogen-estrogen)• Daily for 21 days, 7-day gap• Inhibit ovulation & implantation
Saheli is a non-steroidal, once-a-week pill with few side effects, while normal oral pills are steroidal and taken daily for 21 days. These two differences are the most tested points in NEET.

Your doubts, answered

Is Saheli a steroidal or non-steroidal pill?

Saheli is a NON-steroidal pill. This is its most important feature for NEET. Normal oral contraceptive pills contain steroidal hormones (progestogens, or progestogen-estrogen combinations), but Saheli contains a non-steroidal preparation. So when the question says 'non-steroidal oral contraceptive', the answer is Saheli.

How often is Saheli taken - daily or once a week?

Saheli is a 'once a week' pill. This is a clear difference from normal pills. Ordinary oral contraceptive pills must be taken daily for 21 days (starting within the first 5 days of the cycle), then a 7-day gap. Saheli only needs one tablet per week, which makes it easier to use.

What is the difference between Saheli and normal oral contraceptive pills?

Three differences to remember: (1) Composition - normal pills are STEROIDAL (progestogen / progestogen-estrogen), Saheli is NON-steroidal. (2) Frequency - normal pills are DAILY, Saheli is ONCE A WEEK. (3) Side effects - Saheli has very few side effects and a high contraceptive value.

Does Saheli contain progesterone or estrogen?

No. Saheli does NOT contain steroidal hormones like progestogen or estrogen. It contains a non-steroidal preparation. Do not confuse it with normal pills that use small doses of progestogens or progestogen-estrogen combinations.

Who developed Saheli and why is it important?

Saheli was developed in India at the Central Drug Research Institute (CDRI), Lucknow. NCERT mentions it as an example of Indian research on new and better contraceptive methods. It is important because it is safe, non-steroidal, once-a-week and made in India, so NEET may ask it as a research/example fact.

⚠️ The NEET trap
Saheli is a steroidal pill taken daily like other oral contraceptive pills.
Saheli is a NON-steroidal, ONCE-A-WEEK pill with very few side effects and high contraceptive value.
🧠 NEET flips 'non-steroidal' to 'steroidal' and 'once a week' to 'daily'. Read those two words carefully - they are the whole trap.
