“…The role of multiple inseminations per cycle was also evaluated. A previous study has shown for the same population, but without distinguishing between ejaculates, that there was a slight increase in the success rate when the number of inseminations passed from 1 to 3 (Schwartz et al 1980). In the present study, the pole of multiple inseminations appears to be quite variable, its influence being least for the good quality ejaculates (Table 2).…”

A comparison was made between successful (167) and unsuccessful (1322) insemination cycles in order to evaluate the role in conception of different semen characteristics. The most important semen variable was found to be post-thaw motility: the success rate per cycle increased from 7% when post-thaw motility was less than or equal to 40% to 17% when it was greater than or equal to 65%. Multiple inseminations in a cycle increased the success rate primarily when semen quality was poor. The results of this study show how and to what degree efficacy in A.I.D. can be improved by a judicious choice of the semen to be utilized and the number of inseminations to be practiced.

“…The spermatozoon must be protected during its stay in the female genital tract against the action of host protective systems. In man, the spermatozoon can survive several days as is shown by statistical studies of results obtained in artificial insemination (Schwartz et al, 1980). In the bat, survival can be several months.…”

Summary The seminal vesicle is a gland which appeared late in the evolution of placental mammals. Vesiculectomy leads to very serious subfertility demonstrating the important role of this gland. Secretions of the seminal vesicle act during coitus and the maturation of the spermatozoon, on its mobility, its freezing capacity and the condensation of chromatin. These secretions also act on the female genital tract because they possess immunodepressive capacity. Due to their high concentration of prostaglandins, they can modify the contraction of smooth muscle. As shown by the animal model, they have an antibacterial role in the male genital tract. This explains the relatively low frequency of purely vesicular infections in human pathology. Zusammenfassung Die Bläschendrüse ist eine Drüse, die spät in der Evolution der placentalen Mammalier erschien. Entfernung der Bläschendrüse führt zu sehr schwerer Subfertilität und zeigt so die bedeutende Rolle dieser Drüse. Das Bläschendrüsensekret wirkt auf die Ausreifung der Spermien und postkoital auf die Spermienmobilität, die Einfrierkapazität und die Chromatinkondensation. Das Sekret wirkt auch auf den weiblichen Genitaltrakt und besitzt dort immunsuppressive Wirkung. Aufgrund des hohen Prostaglandingehalts kann es die Kontraktion der glatten Muskulatur modifizieren. Wie im Tiermodell gezeigt, hat das Bläschendrüsensekret eine antibakterielle Wirkung auch im männlichen Genitaltrakt. Dies erklärt die verhältnismäßig geringe Häufigkeit reiner Bläschendrüsen‐Infektionen in der menschlichen Pathologie.

“…In some cases, the insemination procedure is performed in the hospital service to which the CECOS bank is attached; for the most part, however, CECOS managers have obtained the cooperation of private clinicians, who submit their insemination protocols and results for systematic examination. This has enabled the CECOS banks to improve and standardize an insemination protocol, which partially compensates for the decreased fertilizing capacity of frozen semen by the precise timing of inseminations, while economizing on the number of semen doses used per cycle (28).…”

Semen Banking and Artificial Insemination by Donor in France: Social and Medical Discourse

Artificial insemination with donor semen (AID) has recently come into public view—particularly in France—because of its association with a newer technique, the cryopreservation of semen. One of the oldest and simplest of reproductive techniques, used most frequently as a means of compensating for male infertility, artificial insemination was previously confined to the private clinician's office, where maximum confidentiality could be ensured. This shielded all of the parties involved—recipients, donor, and physician—from moral reprobation and the possible legal complications arising from the use of donor sperm. However, in the mid-twentieth century, some physicians and researchers in cyrogenics came up with the idea that the freezing and stocking of donor semen in banks might greatly improve the psychological conditions and facilitate the material arrangements for performing AID. Essentially, the donor's availability would no longer have to coincide with the woman's ovulation, meaning less inconvenience for the donor, more time for screening his medical history and running the necessary tests on his semen, and possibly a certain tempering of AID's adulterous connotations. Although results with frozen semen were not as satisfactory as with fresh (the probability of a pregnancy at any cycle is almost twice as great with fresh semen), the material and psychological benefits were considered greatly to outweigh the lesser efficiency of frozen sperm.
