What Does Menstruation Mean for Women — And Why Don’t Men Experience It?

Menstruation is a natural and essential part of life for many people assigned female at birth. Yet for something that happens monthly for nearly half the population, it’s still widely misunderstood. One common question is: “Why do women menstruate, and why don’t men experience something similar?”

Let’s explore what periods really mean — from a biological, reproductive, and structural perspective.

🌸 What Is Menstruation?

Menstruation, also known as a period, is the monthly shedding of the uterine lining (endometrium) in people with female reproductive systems. It typically occurs when a pregnancy does not happen during a menstrual cycle.

Here’s how it works:

  1. The ovaries release an egg (ovulation) around the middle of the cycle.

  2. The uterus builds up a lining in preparation for a possible pregnancy.

  3. If the egg isn’t fertilized, hormone levels drop.

  4. The uterus sheds its lining — resulting in bleeding through the vagina.

This cycle typically repeats every 21–35 days and is governed by hormonal changes, particularly involving estrogen and progesterone.

🚻 Why Don’t Men Menstruate?

Men, or people assigned male at birth, do not have a uterus or ovaries — the key organs involved in the menstrual cycle. Instead, the male reproductive system is designed primarily for continuous sperm production, not cyclical preparation for pregnancy.

Key differences include:

Feature Female Reproductive System Male Reproductive System
Uterus Present — where the lining builds and sheds Absent
Ovaries Produce eggs and hormones Absent
Menstrual Cycle Monthly cycle driven by hormones No cyclical menstruation
Hormones Estrogen, progesterone, luteinizing hormone Testosterone, luteinizing hormone

So in short: no uterus = no period.

🧠 What Does Having a Period Mean for Women?

Beyond biology, menstruation is a powerful symbol of the reproductive potential, hormonal shifts, and monthly rhythms that many women live with for decades of their lives.

Menstruation can impact:

  • Physical well-being (cramps, fatigue, bloating)

  • Mental health (mood swings, anxiety, PMS)

  • Lifestyle and comfort (work, school, exercise, intimacy)

It also requires resources: access to menstrual products, clean water, education, and rest — which are still not available to many around the world.

That’s why at NYX Collection, we’re passionate about normalizing period conversations, improving access to reusable, body-safe products, and supporting period equity.

🧬 Male vs. Female: Structural Differences

While both male and female bodies are complex and remarkable, they are biologically different in key ways — especially in reproductive function:

Female Body:

  • Uterus, ovaries, cervix, and vagina

  • Monthly cycle from puberty to menopause

  • Capable of menstruation and pregnancy

Male Body:

  • Testes, prostate, seminal vesicles, penis

  • Continuous sperm production

  • No menstrual cycle or uterine system

That said, gender and biology are not always binary. Some individuals may be intersex, or transgender people may experience gender and menstruation in complex ways. It's important to approach these topics with sensitivity and inclusion.

💬 Final Thoughts: Respecting the Cycle

Menstruation isn’t just a “women’s issue” — it’s a human issue. Understanding how and why it happens helps break taboos and encourages compassion, equity, and better care for all.

And while men don’t experience periods, they can be supportive allies — by understanding, normalizing conversations, and advocating for menstrual health as a basic human right.

At NYX Collection, we’re committed to providing reusable menstrual products, like medical-grade menstrual cups and leak-proof period underwear, to empower all who menstruate — while protecting the planet.
