I read here with my wife From popular recipes:

To give birth to a girl:
During conception, the woman should lie with her head to the south.
Conception should occur under the noise of rain.
A man should wear wool trousers so that everything is warm.
Doing love in the afternoon and on weekdays.

To give birth to a boy:
Hide a tail under the pillow and a soldier hat under the back of the woman.
The head of the woman is turned north.
The spouse must wear free family trousers.
During sexual intercourse, a man must sing.

He presented:

The man runs in, grabs his wife, pulls her to the bed, aligns her on the compass, and with the song "Eye smells" begins to fuck. At the same time, a hat and a soldier hat fall out of the pillow.
Well, if the wife is warned in advance.
