Answering :

Once again, the term of sperm "thick" and "dilute" is not really known in the medical world. Apparently, the term comes from unprofessional advertising in the mass media.  normal sperm who ejaculated has a viscosity, which melts later. So please do not be there are sperm term "thick" and "dilute".

To determine whether or not normal sperm, fertile or not,
laboratory tests should be performed. Without laboratory tests, the condition can not be determined male fertility. But laboratory tests only once is not enough.

Regarding the sex of the baby planning, it's another. Planning of sex depends on the comparison between sperm cells that contain the chromosomes of men and women. Both types of these sperm cells is  different Biological, because it can be separated. There are several ways you can do to plan the sex of the baby, even though the result is uncertain.

A simple way is to set the time when sexual relations, manage who is first orgasm, to the use of certain chemicals. Furthermore, there are a more sophisticated way, namely separating the spermatozoa cell types with specific material then the inseminated into the uterus.
