Persons of moderate and regular habits, with strong and sound constitutions, beget healthful infants; while those whose habits are excessively mental, generally produce feeble offspring, though their constitutions and general health may be good. Another cause of feeble children is the abuse of the function of generation by too frequent intercourse. In such cases the semen is thin and watery, being too suddenly secreted. Harvey says that to produce vigorous offspring, the spermatic fluid ought to remain two or three days in its receptacles for its thinner parts to become absorbed, when more vitality will be imparted to it, and hence the more vigorous will be the offspring. It will be thus seen that the proper union of the sexes is at that moment when the mind and body are at rest, and when both parties are in a mood for mutual caresses. Certain moral and intellectual perceptions undoubtedly govern their feelings under such circumstances, and aid in producing that intense pleasurable feeling which a healthy and proper connection will always promote. As to the times when sexual union should be avoided, I would say that during five or six days after the monthly turn of the female commences, it is absolutely unhealthy to both. Married men of cleanly habits will religiously observe the Jewish law in this respect, and wait seven days. It was formerly thought that connection with a female during the menstrual flow, was the origin of a certain sexual disease called gonorrhœa; but such is not the fact. Connection during that period is, however, unnatural, hurtful, and often painful to the female. Neither should there be any intimacy of this kind when the female is troubled with fluor albus, or whites, as then there is danger that the male may contract gonorrhœa. When a girl appoints her wedding day, she should reckon as near as possible a time when she will be fully over her monthly turn. If subject to fluor albus, she should first seek the most efficient means of cure; and if possible, a cure should be effected before she marries. Girls subject to this complaint seldom enjoy the constant sexual intercourse incident to married life. Medical science can manage this disease so easily and effectually by the aid of the Truss, or Abdominal Supporter, that there is no excuse for neglecting it. Unless the strictest cleanliness is practiced by the wife while she has the whites, she may give her husband the disease called gonorrhœa. She should never have any connection with him in the morning until she has risen and washed the part thoroughly. Suspicious men have often believed their wives unfaithful because they have contracted gonorrhœa from the whites. But the fact is well known to medical men that that alone is the original cause of the disease.
