**How many sperms will be produced from one germinal cell of seminiferous tubules in man?**

In the process of spermatogenesis, which occurs in the seminiferous tubules of the testes, germinal cells undergo several divisions and differentiation to produce mature sperm cells called spermatozoa. Let's explore the stages of spermatogenesis and the number of sperms produced from one germinal cell in detail.

**Stages of Spermatogenesis:**
1. **Spermatogonium Division:** Spermatogenesis begins with the division of spermatogonia, which are diploid (2n) germ cells located along the seminiferous tubules. These cells divide mitotically, with one cell remaining as a spermatogonium and the other differentiating into a primary spermatocyte.
2. **Primary Spermatocyte Division:** The primary spermatocyte, which is still diploid, undergoes the first meiotic division (meiosis I). This division results in the formation of two haploid (n) secondary spermatocytes.
3. **Secondary Spermatocyte Division:** Each secondary spermatocyte undergoes the second meiotic division (meiosis II) to produce two haploid spermatids. This division results in a total of four haploid spermatids being formed from one primary spermatocyte.
4. **Spermiogenesis:** Spermatids undergo a process called spermiogenesis, during which they differentiate into mature spermatozoa. This involves the formation of a head, midpiece, and tail, along with the development of flagella for motility.

**Number of Sperms Produced:**
From one germinal cell, which is a spermatogonium, a total of four mature spermatozoa are produced. This is because each primary spermatocyte gives rise to four spermatids, and each spermatid eventually matures into a spermatozoon. Therefore, one germinal cell undergoes a series of divisions and differentiations to produce four functional sperm cells.

**Sexual Reproduction: Juvenile Reproduction:**
It's worth noting that the concept of "juvenile reproduction" is not related to sperm production from germinal cells. Sexual reproduction in humans involves the fusion of a sperm cell with an egg cell (oocyte) during fertilization, resulting in the formation of a zygote. This zygote undergoes subsequent divisions and differentiations to form an embryo, which eventually develops into a fully formed individual. Juvenile reproduction, on the other hand, refers to the reproductive capabilities of young individuals before they reach maturity.

In conclusion, one germinal cell of the seminiferous tubules in men produces four mature spermatozoa through the process of spermatogenesis. This process involves several divisions and differentiations, resulting in the formation of functional sperm cells.
