How Body Systems Work Together for Sperm Production

Bellevue Sperm Bank collects sperm donations to support individuals seeking to become parents but lacking a sperm source. Donors in the program provide a sperm source for treatment through weekly donations.

Different lifestyle choices can impact sperm production, from ingesting nicotine products to a lack of sleep. It takes overall wellness and the body working together to create a healthy reproductive system and high-quality sperm samples.

Here we break down the roles of body systems from the brain to reproductive organs and their role in a functioning reproductive system.

Reproductive Organs

Starting with the heart of the matter, the reproductive system. The organs include the penis, testicles, and supporting structures. This is where sperm are made and stored. It is clear how the reproductive organs are important for sperm production.


The brain is the command center for the body in its entirety, orchestrating needs and wants. Based on feedback from the body, the brain triggers different events to begin and end. An example is feeling hungry. The body sends signals that there is low blood sugar, and the brain then sends hunger signals. Then shuts off the system after eating.

The same goes for reproduction and coordinating events that are needed for sperm production.

Endocrine System

The endocrine system controls your hormones. Hormones are the signals your body uses for messaging. They are responsible for hunger, energy levels, growth, mood, and reproduction. Organs involved include the brain, thymus, thyroid, pancreas, adrenal glands, and testicles.

Testosterone is produced in the testes and then stimulates sperm production, also in the testes. High levels of testosterone signal the brain to reduce sperm production and testosterone production. This is how hormones can communicate with both the testes to produce sperm, and to the brain to prevent overproduction.

Circulatory System

A well-functioning circulatory system is required for reproductive function. Erections are started and maintained by the circulatory system working with the organs of the reproductive system. Additionally, the circulatory system transports hormones throughout the body so they reach the target receptors.

Everything Else

Other body systems are indirectly involved in reproductive functioning, if anything else is out of commission it may interfere with other activities. For example, try getting in the mood when you have a toothache.

What can you do to improve reproductive health?

We see how the entire body plays a role in reproductive function. Keeping a healthy mind and body will keep everything running as it should. Here are some tips to help:

  • Get plenty of rest
  • Eat fresh fruits and vegetables
  • Stay hydrated
  • Reduce alcohol consumption
  • Avoid nicotine products
  • Get regular exercise

Keeping up with annual healthcare visits will help you stay on top of your overall health. Donors at Bellevue Sperm Bank receive routine physicals, STI testing, and other health screenings. Additionally, donors are all compensated for each donation.
