But that the obstacle offered to conception by gonorrhoeal infection is by no means so powerful as Nöggerath and his supporters believed, is shown by the investigations of Oppenheimer, who, in Kehrer’s clinique at Heidelberg, examined 108 pregnant women for the presence of gonococci, and found these organisms, pathognomonic of gonorrhoeal infection, in no less than 30 of them, that is, in 27.7%. Thus, in this large number of cases, pregnancy had occurred notwithstanding the presence of gonorrhoea. Lower, again, in Schröeder’s clinique, examined 32 patients during the lying-in period, and detected the presence of gonococci in 26; an experience which also proves that gonorrhoeal infection is no bar to pregnancy. Dunstone has recently recorded 5 cases in which, notwithstanding the existence of gonorrhoea, the women became pregnant once or several times.

In the “Medical Brief” the question was mooted, “Can a woman have children subsequently to being infected with gonorrhoea?” Numerous affirmative answers were received; and among them one mentioning the case of a woman who was infected with gonorrhoea at the age of 18, and subsequently gave birth to 8 children.

The question of sterility in prostitutes has also attracted attention, since these women may be regarded as invariably infected with gonorrhoea. Meissner and Jeannel speak of the infertility of prostitutes as a well-known fact; and the latter states that, whereas, according to Montesquieu, to every 100 women in France, on an average 341 children are born, of which 200 grow up, to 100 prostitutes in Bordeaux there were born 60 children only, and of these but 21 attained maturity. Marc d’Espine affirms that among 2,000 prostitutes not more than two or three will have children in a year. Parent-Duchatelet, on the other hand, regards the sterility of these women as a purely temporary affair, and writes: “les prostituées conçoivent souvent, mais elles avortent fréquement;”[[49]] and this frequency of abortion he attributes to two causes, in the first place to deliberate induction of abortion, and in the second place, to their mode of life. He continues: “cette fécondité a lieu surtout lorsque, quittant leur mettier, elles se marient ou s’attachent à un seul homme; dans ce cas les grossesses se succèdent, elles sont toujours heureuses et les infants qui en proviennent sont aussi vivaces que les autres;”[[50]] thus, in his opinion the sterility of prostitutes lasts only as long as they pursue their occupation.

The question as to what influence, if any, gonorrhoeal secretion has per se upon the semen, has often been asked, but not yet satisfactorily answered. We have no certain knowledge whether the gonococci, the pus cells, or one of the toxins of the secretion, exercises a deleterious influence upon the vitality of the spermatozoa; it is certainly possible that this may be the case, for the diplococci, just as much as streptococci and staphylococci, are found not only within the cells, but also in the intercellular fluid and in the detritus, and so must be brought into intimate contact with the spermatozoa; but inasmuch as quite a number of persons who are at the time actually suffering from gonorrhoea beget children, we are compelled to assume that for the harmful influence, if any such exists, to be exercised, a prolonged contact of the semen with the gonorrhoeal pus is necessary. In cases of gonorrhoeal epididymitis and prostatitis, and also in gonorrhoeal urethritis, no such prolonged contact occurs; but when the vas deferens or the vesicula seminalis is inflamed, the contact is more prolonged, and may suffice to destroy the vitality of the spermatozoa, which are extremely sensitive to chemical stimuli. In 8 cases observed by Kroner, the fruitful coitus was unquestionably effected when the husband was suffering from still active gonorrhoea; in all the cases the children were born at full term, and all suffered from conjunctival blenorrhoea. That gonorrhoea often fails to induce sterility, is shown by the familiar fact that a woman frequently has one child after another, all infected with this conjunctival form of gonorrhoea, showing that the mother remains fertile notwithstanding the persistency of the gonorrhoeal infection.

Upon the investigation of 60 carefully written clinical histories, dealing with the relation between proved gonorrhoeal infection and a sterile marriage, Grechen has drawn up the following table, showing the various ways in which chronic gonorrhoea may give rise to sterility:

A. Absolute Sterility.

a. Owing to impossibility of fertilization, in consequence of defective formation of spermatozoon or ovum:

b. Owing to impossibility of pregnancy, although semen and ovum may be normal, and fertilization can be effected:

Gonorrhoeal endometritis of atrophic character.
