What reading level is The Sexual Life of Woman in Its Physiological Pathological And Hygienic Aspects book?
To quickly assess the difficulty of the text, read a short excerpt:
By the addition, however, of concentrated solutions of neutral salts, of albumen, of urea, etc. , it is possible to reanimate these motionless spermatozoa, so that they once more are seen to perform active movements. Moderately concentrated animal secretions of an alkaline reaction are favourable to the motor activity of the spermatozoa, whilst on the other hand dilute and acid secretions, such as urine, acid mucus (including the THE SEXUAL EPOCH OF THE MENACME. 313 acid vaginal mucus), and cat...arrhal secretions, even when alkaline in reaction, have a depressant influence on this activity. Caustic potash and caustic soda stimulate the movements of the sperma- tozoa. When they are cooled down to a temperature below 15 C. (59 F. ), the movements cease entirely. Salts of the heavy metals, and mineral acids in solution, also bring their movements to a pause. Frequent repetition of coitus causes a diminution in the number and in the motor activity of the spermatozoa.
Semen which contains no spermatozoa, or in which the sperma- tozoa are motionless, is absolutely devoid of fertilizing power; in the case of such semen, it makes no difference whatever that the external genitals of the man generating it are strongly formed, that his testicles are of normal size, and that erection and ejaculation take place promptly.
