Fertility Facts: Sperm Regeneration

sperm takes 74 days to matureThe sperm regeneration cycle takes about 74 days.

It is generally known that most men produce millions of new sperm every day. However, you might not know that these new sperm take about 2 ½ – 3 months to fully mature or that when sperm are initially formed they lack the ability to swim forward or fertilize an egg.

Sperm are living cells within the male body and are subject to whatever conditions the rest of the body is exposed to throughout their maturation cycle. Extreme temperatures, smoking, drug use and poor diet can all impact the quality of sperm. For this reason, men looking to increase the chances of conception may make lifestyle changes. It is important to keep in mind that healthy sperm will not be ready to fertilize an egg until the new batch of sperm, developed under the healthier conditions, is mature. Meaning, after making a lifestyle change, it is recommended to wait about 3 months before trying to conceive.

When considering conception, it is also important to try to find the best sperm available to reach and fertilize the egg. In this effort, it is recommended that men abstain from ejaculating for 2 to 3 days. Men that are ejaculating more often show signs of a decreased sperm count. This rule goes for couples who are trying to conceive on their own as well as men that are producing a semen sample for fertility treatments, such as IUI or IVF.

    Please is it possible to know when the produced sperms are matured? Or how can the life cycle be calculated?

  4. Shady Grove Fertility says:

    Hi Stan – The sperm mature at the end of this process, approximately 2.5-3 months. Life cycle has been calculated during studies where trauma and other variables done. You can see that sperm produced after the event would no longer show signs of the trauma.

    Hello! My husband had a second vasectomy reversal done in June. The first reversal was performed in 2010 and was successful at first. 6months post surgery pulled vas apart on the left and scarred over on the right leaving us unable to conceive. We had our first SA done in August and the count was extremely low, 1.2 million. Thankful to be blessed with a count, but hopeful for stronger numbers and that the vas does not pull apart and scar over again. Is this normal as far as a count goes post reversal? Or should we be concerned? Thanks!

      I was disappointed with the same occurrence. Three months post reversal, a SC came out normal at 30mil… 6 Months after trying to conceive I went for a 2nd SA and Z E R O… :( I’m on Anti Inflammatory meds now and praying it was a scar tissue problem and that the meds open me back up. Very disappointing
