Hi,

My partner smokes pot and we are trying to conceive, I have heard through the great vine that smoking pot may cause you to 'shoot blanks' is this correct?:)

Found this...

The findings showed that both the volume of seminal fluid and the total number of sperm from marijuana smokers were significantly less than for the control group of fertile men. They also found significant differences in HA and velocity, both before and after washing. It is believed that an active ingredient in marijuana - tetrahydrocannabinol (THC) - could be causing these changes.

"The sperm from marijuana smokers were moving too fast too early," explained lead researcher, Dr. Lani J Burkman. "The timing was all wrong. These sperm will experience burnout before they reach the egg and would not be capable of fertilisation."

"We don't know exactly what is happening to change sperm functioning," she said, "but we think it is one of two things: THC may be causing improper timing of sperm function by direct stimulation, or it may be bypassing natural inhibition mechanisms … The bottom line is, the active ingredients in marijuana are doing something to sperm, and the numbers are in the direction towards infertility."

Dr. Burkman admitted that many men who do smoke marijuana have fathered children, but said, "The men who are most affected are likely to have naturally occurring borderline fertility potential, and THC from marijuana may push them over the edge into infertility."


... it's from Effects of marijuana and coffee on male fertility, sperm motility (http://www.bupa.co.uk/health_information/html/health_news/211003sperm.html)

And there's Effects of Marijuana on Sperm Motility ; Seattle Washington WA (http://www.swedish.org/17062.cfm)

Yes, That is correct.

Hahah it's grape vine isn't it?

Well maybe not "blanks" just a lot lower caliber. So it makes it harder but not impossible.

Any kind of drugs can also effect the health of the sperm so that would also effect the viability of the fetus.

Why would you want to have a baby with a pot smoker, it won't be good for the baby once it is here. He should quit, not because of the fact that your chances of getting pregnant are reduced but because he should be a mature adult before considering becoming a parent. Yikes.

Exactly. His smoking habits may very well mean damaged sperm which can affect the health of your fetus and if you can carry it to term.
