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.

    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

    I was someone who used to have sex very frequently and now I have my semen very watery and light from the normal semen. I am scared of what might the problem. Could lead to low sperm counts or make me infertile. Could this also means that my sperm bank is empty. Am confused here so please help me out. Thanks.

    Pls, i need a clarification. You said said it takes 2.5-3 months for sperms to mature. Does that mean sperms must mature before it can ejaculated out. In other words, is all ejaculated sperms matured?

      Hi Kunle – Yes, all sperm remain in the epididymis for this time to mature. That isn’t to say all ejaculated sperm are normal and can produce a healthy pregnancy. But taking steps to improve lifestyle can go a long way to increasing the volume and proportion of normal mature sperm that are ejaculated.

    Okay so it takes sperm approximately 74 days to mature. What I’m not getting is that am I supposed to wait that long? Because other articles state that after a week with no ejaculation, it can affect sperm motility. And it takes approximately 36 hours for a man to replenish sperm after ejaculation. So if I’m having sex every 36 hours, how does that give my sperm a chance to mature.

      Hi Wayne – Great question.
      You certainly don’t have to abstain from intercourse for 74 days! The sperm maturation is a process. In the body, at the same time, you will have immature sperm that are brand new that will gradually mature over the next couple of months as well as fully mature sperm. The idea would be to abstain for a few days (based on your doctors recommendation) to build up enough mature sperm in your ejaculate to determine a sperm count and motility. In the case of intercourse or ejaculating to use for fertility treatment, the goal is to get enough mature sperm in the sample to increase the chances of fertilization.
      Hope this clarifies things!

    Thanks Shady Grove.

    I have been following your responses. Correct me if I understand your reply to Waynes enquiries as “ejaculation or frequent sex within the 74 days window for sperm to mature will not affect the process”.

    Also I hear zinc supplements or foods high in zinc like Oysters are the way to go to improve quality, motility and mobility of these swimmers.

    Hi,

    We had IUI done and the first round my spouse’s sperm count was very high, in the area of 190 million. The next month and a half or so his count was 93 million for the second round. Is it normal to have such a drastically different sperm count within the span of a month and a half?

      Hi Alex – It isn’t uncommon to have drastic changes in sperm quality or count from one test to the next, which is why you have a preliminary semen analysis, but the sample used for an IUI or IVF treatment cycle gets tested again. There are many factors that can swing the count, including changes to lifestyle and last ejaculation. Although likely nothing is wrong, you may want to talk with your nurse or physician to ensure that your husband is doing what he can to optimize his sample.

    Hi, I am very overweight and have some poor semen figures. If I star changing my lifestyle today and my diet will it take three months from now for my sperm to get better or three months from when I lose a significant amount of weight? Also I hear conflicting things on how often you should have sex during ovulation and outside some say every day others say every other please clarify. Thanks.

    Hello Please help if you can!
    My wife and I are trying to have our second baby. We were going to start trying tonight but we had a small incident where our microwave caught fire while we were out, not in use just wiring issue that caught the wires on fire. I went in when the house had smoke and realized the microwave had partially melted from heat. So I inhaled some smoke and air born plastics from the melted microwave, not sure if this effects the sperm. It was brief maybe 5-10 minutes, my throat and eyes burned a little but it wasn’t a really thick smoke.

    Should we wait the 74 days until the sperm is regenerated or are we being over catious. Thanks in advance!

    Yo, so, here’s a decent question regarding accounts of multiple ejaculates, sperm counts and the like.

    Prior to last night, I have ejaculated at least once a day, consistently mind you, for about a week or so and last night with my fiancée, I accidently came inside of her.
    The last time I ejaculated. There was very little content as I had dome it earlier that day anyways, then when I got home from work we repeated the act.
    I’m wondering the chances of pregnancy of that minute ammount, her being on top, and how low the count in a batch would be and if she would get pregnant? We aren’t exactly trying, but we’ll I’m worried something will happen.

      Dear ShallowHal only one mature sperm is enough to fertilize an egg. so there is lacks of chance of pregnancy if you aren’t ready for that you have to take pregnancy prevention steps.

    Shady Grove Fertility, please answer my questions:
    1. After 46 years old, I discover that my urge to have sex drop to once every 2 weeks instead of 2-3 times a week. Is this due to my sperm reproduction?
    2. The penis is not as hard as in the past and cannot maintain for 5 mins. I nowadays sleeping at 1 am instead of before 12 midnight in the past.
    3. Viagra and Cialis do not help. Any natural remedy? I’m taking Prepionyl-L-Carnitine 2g twice a day.
