A health worker lists five hormonal or emergency methods: the daily pill, an injectable, a skin implant, Saheli, and an emergency contraceptive.
- Which two act in the same way as the pills, but for a much longer time?
- Which one is a non-steroidal pill that is taken once a week?
- Within how many hours of coitus can an emergency contraceptive be used?
- Name the three ways in which the daily pill prevents a pregnancy.
Need a reminder? The key ideaShow
The pills are taken for days, and then there is a gap of days. The pills keep FSH and LH low, so there is no LH surge and no ovulation. In a natural cycle the LH surge comes near day . Emergency methods are used within hours of coitus. Injectables and implants act like the pills for a longer time. Saheli is a non-steroidal weekly pill.
The worked solution
Have you tried it?
Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, go through the solution one step at a time, and check each step against your own.
Given. Five methods.
Plan. Recall what NCERT says about each.
Step 1. The long acting methods. The injectable and the implant. They act like the pills, and their effect lasts much longer.
Step 2. The weekly pill. Saheli. It is non-steroidal.
Step 3. The time. hours.
Step 4. The three ways. The daily pill prevents ovulation, prevents implantation, and changes the cervical mucus so that sperms enter with difficulty.
Answer: the injectable and the implant; Saheli; hours; ovulation, implantation and the cervical mucus.
Check. Each answer comes from the text of NCERT, and none needs a number except the hours.
Watch out. An emergency contraceptive is for an emergency, and it is not a replacement for a regular method. A health worker or a doctor should advise any person.
