Hello dear, Thank you for your contact to health care magic. I read and understand your concern. I am Dr Arun Tank answering your concern. We can t say it on the basis of the consistency of the semen alone. I advice you should go for testing of the semen in the laboratory. If it stats that the semen count is low. Than we can say that this is the reason for not conceiving. Few minutes after ejaculation ejaculates will turn into liquid. So we can t assume as to whether it is faulty or not. In some cases achieving pregnancy is some what difficult but if you try you can achieve it though it may take some time. Please take good sleep at night, avoid stress, eat green vegetables and fruits. This will help your boy friend to achieve good sperm count and erection. I will be happy to answer your further concern on bit.ly/DrArun. Thank you, Dr Arun Tank Infectious diseases specialist, HCM.
