Large spunk volume

Males in many species differentially allocate sperm and seminal fluid depending on certain social variables, including perceived sperm competition and female reproductive status. In some species, males reduce their investment in sperm quantity or quality upon repeated matings with the same female and increase such investment when mated to a novel female. We tested for effects of stimulus habituation and novelty on ejaculated semen parameters in humans. We analyzed ejaculates produced through masturbation with stimulation from sexually explicit films. When males were exposed successively to the same female six times, we saw no change in ejaculate parameters between the first and sixth exposures to the same female. However, ejaculate volume and total motile sperm count significantly increased when males were exposed to a novel female.

Hyperspermia: Symptoms, Causes, Fertility, and More

But TRT has been linked to lower sperm count , and Ted and his wife were trying to get pregnant. So Ted started doing some research on the internet for supplements that could help raise his sperm count, which in turn led him down the path of trying to increase the actual volume of his semen—or, as he put it, "I started looking at ways to increase my loads," he says. After stumbling on a few Reddit threads devoted to the topic, Ted started taking supplements to increase his semen volume, including zinc, vitamin D3, and folic acid. At one point, he says, he was taking more than a dozen pills per day, spending hundreds of dollars on supplements per month. He swears that not only did his semen volume increase while taking the pills, he also "discovered the ability to be able to go for a second round" of sex with his wife after years of struggling with ED. That's true when it comes to penis size , and it's true when it comes to our, well, come. Before we go any further, let's clarify the difference between semen and sperm.

What You Should Know About Hyperspermia

Semen volume is not related to the sperm volume within it. If you have any medical questions or concerns, please talk to your healthcare provider. The articles on Health Guide are underpinned by peer-reviewed research and information drawn from medical societies and governmental agencies. However, they are not a substitute for professional medical advice, diagnosis, or treatment. Like seemingly everything related to male sexuality, semen is, at times, a point of pride, concern, complications, and potential anxiety.

I really enjoy reading some of your articles as a lot of the queries are relevant to many! These are the questions that bother many people, but they are just too shy to ask. This week, I would like to put Dr G on the spot for another question about sexual health that bothers me, and I'm sure other men too.
