Find the incorrect match .w.r.t . Increase in the levels of following hormones

Options

A. Oxytocin - Uterine contraction during labour
B. Prolactin - Lactation after child birth
C. Progesterone - Uterine contration
D. Luteinising hormone - Stimulates o vulation

Answer

To solve the question of finding the incorrect match regarding the increase in hormone levels, we will analyze each option step by step.

### Step-by-Step Solution:

1. **Option A: Oxytocin - Uterine contraction during labor**
- Oxytocin is a hormone produced by the posterior pituitary gland. It plays a crucial role in stimulating uterine contractions during labor (parturition). Therefore, this match is correct.

2. **Option B: Prolactin - Lactation after childbirth**
- Prolactin is another hormone produced by the anterior pituitary gland, and it is primarily responsible for milk production (lactation) after childbirth. This match is also correct.

3. **Option C: Progesterone - Uterine contraction**
- Progesterone is a hormone that helps maintain pregnancy and inhibits uterine contractions. During labor, the levels of progesterone actually decrease to allow for uterine contractions to occur. Thus, this statement is incorrect as progesterone does not promote uterine contractions.

4. **Option D: Luteinizing Hormone (LH) - Stimulates ovulation**
- Luteinizing hormone is responsible for triggering ovulation, which occurs around the 14th day of the menstrual cycle during the LH surge. This statement is correct.

### Conclusion:
The incorrect match is **Option C: Progesterone - Uterine contraction**.
