=What are the causes of sterility in man?=--Sterility is much more common than impotency. Venereal disease is the most common cause. Excessive secret sin may temporarily deprive the semen of its fecundating power. Some malformation of parts is sometimes responsible. =Is the wife ever incapable of coition?=--Very rarely. Excessive sensitiveness of the parts is the most common cause. In such cases, which are very rare, the sexual act would be so painful as to be wholly unbearable. Such cases require medical treatment. The sooner it is begun, the better. A very rigid hymen, or the vagina being partly absent from birth, or grown together from an accident, may make coition impossible. In the first and last case a surgical operation can remove the difficulty. Eighty per cent. of sterile wives, are due to gonorrheal infection received from their husbands who thought themselves cured. =Should husband and wife sleep together or in separate beds?=--In many cases, owing to lack of self-control, it would be better for them to sleep in separate beds. If there is no other reason why they should sleep apart, and they have self-control, it would be better to sleep in the same bed. =Are women as passionate as men?=--Centuries, of the double standard of morals, have established by heredity, more of passion in man than exists in the average woman. Among the lower animals, except where they have been forced into polygamy by man, the male controls himself fully as easily as does the female. Many women do not feel any sexual excitement whatever, others only to a limited degree. This is doubly true of women during pregnancy, and lactation. Most normal women seek sexual gratification to please their husbands or out of a desire for motherhood. There are some women who have inherited or acquired strong sensual natures. =Should coition take place during the menses?=--Absolutely no. For sanitary and hygienic reasons, if no other. =What is the “climacteric” period, or the “change of life” in a woman?=--This occurs between forty and forty-nine years of age. It usually covers a period of from two to five years. The menstrual flow often occurs every few days. This is often a critical period in a woman’s life. When this is completed they are sterile, or incapable of reproduction. =Should sexual relations take place during the “change of life”?=--For sanitary reasons, it should not. For the hygienic reason, that it would most likely cause flooding, it should not.
