Which one of the following is an example of Hormone releasing IUD ?
Multiload 375
CuT
LNG 20
Cu 7
The Correct Option is C
Solution and Explanation
To determine which of the given options is an example of a Hormone Releasing Intrauterine Device (IUD), it's essential to understand the types of IUDs available:
- Copper IUDs: These devices release copper, which acts as a spermicide. Examples include:
- Multiload 375
- CuT
- Cu 7
- Hormone Releasing IUDs: These release hormones, typically progestins, to prevent pregnancy. The specific hormone used is Levonorgestrel (LNG). An example of a hormone releasing IUD is:
- LNG 20
Conclusion: Based on the explanation, the correct answer is LNG 20, as it is the only hormone releasing IUD listed among the options. The other options (Multiload 375, CuT, and Cu 7) are copper-based and not hormone releasing.
Hint: Remember, hormone releasing IUDs usually contain "LNG" in their name, indicating the presence of Levonorgestrel.

Read the following passage and answer the questions that follow. Prevention is the frontline response to drug use. Effective interventions address the underlying conditions contributing to drug use, such as a lack of connection to family or community, instability, insecurity, trauma, mental health issues, etc. When addressed, these factors can effectively prevent the initiation of drug use and the progression to drug use disorders. Study the few key figures of drug use given below and answer the questions that follow.
(a) What do you infer from the figures in Table No. 1 about the people with drug use disorders, 2022 (in million)? State any two of your observations.

- In the life cycle of a {Plasmodium, once the sporozoite enters the blood of the host, it invades the hepatic portal system, resulting in occurrence of change in the host body, leading to malaria
A. Sporozoite enters the hepatocytes and divides by schizogony leading to formation of cryptomerozoites
B. Inside RBCs, the micro-metacryptozoites become rounded and modify into a young trophozoites.
C. As the trophozoite grows in size, a central vacuole is developed so that the nucleus is pushed to one side into the peripheral cytoplasm, leading to amoeboid stage.
D. In Amoeboid stage the small red eosinophils granules appear in the cytoplasm of the host corpulses as Schuffner's granules}

Concepts Used:
Human Reproduction
Reproduction in human beings involves the fusion of male and female gametes that produces in their reproductive system.
Male Reproductive System:
The male reproductive system comprises:
- Testicles (testes): A pair of oval-shaped organs masked in a pouch known as the scrotum. They manage the production of sperms and the male hormone testosterone.
- Scrotum: It is a sac-like organ that hangs under the penis and behind it. It is the house of the testes, or testicles, and maintains a temperature that is needed for the production of sperm by it.
- Vas deferens: The sperms produced in testes are stored in a tube known as the epididymis. Here the sperms get matured and pass to the urethra via the muscular tube known as vas deferens.
- Accessory glands: This includes three glands, namely the prostate gland, seminal vesicles, and Cowper’s gland. The secretions from the mentioned three glands mix to form a fluid known as semen. Semen nourishes the sperm, raises the volume, and helps in lubrication.
- Penis: The penis is a cylindrical tube that serves as both an excretory organ, and a reproductive organ. It transfers sperms into the vagina during sexual intercourse.
Female Reproductive System:
The female reproductive system is active before, during, and after fertilization as well. It comprises the following parts:
- A pair of ovaries: A pair of ovaries produce and stores ovum in them. They also produce a female hormone known to be estrogen.
- Fallopian tubes (Oviducts): They are the area of fertilization. They connect both the ovaries with the uterus.
- Uterus: Uterus is the place of development for the embryo.
- Vagina: The part that connects the cervix to the external female body parts is called a vagina. It is the passage for the penis during coitus as well as a fetus during transfer.
