Human Reproduction in Poetry | Class 12 NCERT Biology

Prelude to Creation 

In the cradle of life, a tale unfolds,
Of human birth, a wonder untold.
A journey that starts so small, unseen,
Yet blossoms into a soul, pristine.

The Male Reproductive Tract 

A warrior strong, the male must be,
To bring forth life, with energy free.
The testes lie in scrotal hold,
Cooling seeds of life untold.

Seminiferous tubules weave a tale,
Where sperm arise, so light, yet hale.
Sertoli cells, the nursemaids wise,
Guide the sperms till strength they rise.

Vas deferens, a passage fleet,
Carries warriors to fate they meet.
The prostate gland and seminal vesicle,
Give nourishment rich, a vital miracle.

The Female Reproductive Tract 

A temple sacred, the female bears,
Where life takes root, with tender care.
Ovaries, two, with eggs they store,
Each cycle brings one to the fore.

The fallopian tubes, a bridge so fine,
Guide the ovum, in perfect line.
If sperm arrives, a dance begins,
A zygote forms as life begins.

The uterus, a home so warm,
Prepares itself in cyclic form.
Endometrium grows, soft and lush,
Awaiting life in gentle hush.

Gametogenesis: The Beginning of Life 

In gametes small, the secret lies,
A fusion bright ‘neath cosmic skies.
Spermatogenesis, a mighty feat,
Millions formed, yet one will meet.

Oogenesis, a cycle rare,
One egg released with utmost care.
Meiosis plays its destined role,
Halving cells to make them whole.

5. The Menstrual Symphony A monthly rhythm, nature’s song,
Menstrual cycle, thirty days long.
Follicular phase, the start so bright,
Egg matures in morning light.

Ovulation strikes like golden dawn,
A single egg, its path is drawn.
Luteal phase, with corpus true,
Progesterone brings a hopeful view.

If union fails, the walls must break,
A crimson tide, the cycle wakes.
Yet life prepares, with hope anew,
For another chance to form and bloom.

Fertilization: A Celestial Union 

When sperm and ovum meet in glee,
A zygote forms, the first to be.
Deep within the fallopian space,
A miracle sparks in time’s embrace.

Implantation and Gestation 

Blastocyst travels, a journey bold,
To find the womb, so soft to hold.
Implanting deep, it starts to grow,
With love and warmth, a mother's glow.

Placenta forms, a bridge of grace,
Nutrients flow, a life to trace.
Nine months pass in tender phase,
A heartbeat strong, a face to gaze.

Parturition: The Arrival of Life 

With labor’s cry, the moment nears,
A mother’s joy, a mother’s tears.
Uterine waves, so strong, so true,
Guide the infant, fresh and new.

A breath is drawn, the first so pure,
A newborn cries, a future sure.
Thus completes the cycle vast,
A journey grand, a story cast.

A: The menstrual cycle typically lasts 28 days but can range between 21 to 35 days in different individuals.

Q2: What is the main role of FSH in females?
A: Follicle Stimulating Hormone (FSH) helps in the growth and maturation of ovarian follicles in females.

Q3: How is the sex of a baby determined?
A: The sex of a baby is determined by the sperm. An X-chromosome sperm leads to a female (XX), while a Y-chromosome sperm results in a male (XY).
