Sperm meaning in Hindi is शुक्राणु (Shukranu). Sperm (spermatozoon) is the male reproductive cell (male gamete) produced in the testes. Each sperm has a head (containing the nucleus with 23 chromosomes / haploid), a midpiece (energy for movement), and a tail (flagellum, for swimming). This is covered in NCERT Class 10 Science Chapter 8 — How Do Organisms Reproduce?
Sperm = शुक्राणु (Shukranu) in Hindi.
Male gamete; produced in testes; haploid (23 chromosomes).
Structure: Head (nucleus + acrosome), Midpiece (mitochondria), Tail (flagellum).
Sperm + Ovum → Fertilisation → Zygote (46 chromosomes).
~200–300 million sperm per ejaculation; lifespan in female body: 2–5 days.

Sperm in Hindi: • English: Sperm / Spermatozoon (plural: Spermatozoa) • Hindi: शुक्राणु (Shukranu) • Male gamete = पुरुष युग्मक (Purush Yugmak)
Sperm — Key Facts:

Structure of Sperm (शुक्राणु की संरचना):
Role in Reproduction: • Sperm + Ovum (अंडाणु) = Fertilisation (निषेचन) • After fertilisation: Zygote (युग्मनज) formed → 46 chromosomes • Fertilisation occurs in the fallopian tube (फैलोपियन ट्यूब)
