Suggest and explain assisted reproductive techniques which will help a couple to have children, where the female had a blockage in the fallopian tube and the male partner had a low sperm count.

Explanation

To help a couple conceive where the female has a blockage in the fallopian tube and the male partner has a low sperm count, several assisted reproductive techniques (ART) can be suggested. Here is a step-by-step explanation of the most suitable techniques:

### Step 1: In Vitro Fertilization (IVF)
- **Explanation**: IVF is a widely used assisted reproductive technique where the egg and sperm are combined outside the body in a laboratory setting. After fertilization, the resulting embryo is cultured for a few days before being transferred to the uterus.
- **Reason for Use**: Since the female has a blockage in the fallopian tube, IVF bypasses the need for the sperm to travel through the fallopian tubes, allowing fertilization to occur in vitro (in the lab).

### Step 2: Intracytoplasmic Sperm Injection (ICSI)
- **Explanation**: ICSI is often used in conjunction with IVF, especially when the male partner has a low sperm count. In this technique, a single sperm is injected directly into an egg to facilitate fertilization.
