In this study the presence of Mycoplasma species in patients suffering from infertility was examined. 41 women and 37 men were examined, including 31 couples, and ten single women and six single men. Samples of vaginal and cervical mucus were taken from each woman, and samples of seminal fluid from each man. Identification and typing of the organisms were performed on the basis of microscopic and cultural characteristics and inhibition of growth by specific antibodies. Out of the 78 patients examined, 35 harboured Mycoplasma, either as Ureaplasma urealyticum or Mycoplasma hominis. Further investigation is needed to determine the clinical significance of these findings.

There is a vast amount of evidence linking the presence of genitourinary infection with infertility. Infection in either partner can result in specific effects on sperm function, accessory sexual gland dysfunction, and the induction of immunologic responses in either partner. Careful investigation for infection should be undertaken in every couple with the complaint of infertility. Treatment needs to be individualized in each instance.

Examination of 499 autopsies in Ibadan revealed S. haematobium infection in 98. Digest and histopathologic data were recorded for 88 of these cases (54 males and 34 females). The intensity of schistosomal infection was classified as mild, moderate, or severe on the basis of the egg load per gram of bladder tissue. The majority of cases (64%) demonstrated mild infection. Although the frequency of infection increased with age in males, the intensity decreased significnatly after age 40. Changes induced in the appendix, brain, pancreas, and genital organs by schistosomal infection were directly related to the intensity of the infection. The digest and histologic methods, respectively, indicated the following frequencies of infection: appendix, 37% and 24%; pancreas, 17% and 0; brain, 0.01% and O. The paucity of ova recovered from the brain in this study contradicts previous findings. In terms of male genital organs, the seminal vesicles showed the greatest frequency and intensity of infection, followed by the prostate, testes, and epididymis. Despite high ova loads, lesions were noted histologically in only 7 of 54 seminal vesicle sections. Digest studies on the prostate noted ova in 31.5% of cases, but ova were noted histologically in only 8 sections. With regard to the testes, ova were detected in only 6 digests and no lesions were found histologically. The epididymis was the least affected male organ. Infection in the cervix and vagina had frequencies of 41% and 40%, respectively, but the intensity of infection was greater in the vagina. The ova load was never heavy in the cervix. Digests in the ovaries were positive in 31%, but no ova were seen histologically. The ovary is considered to be more severely affected in S. mansoni infection. Digests were positive in only 11% of cases for the fallopian tubes and 20% of cases for the uterus, and no lesions were noted histologically in either organ. Schistosomiasis is an uncommon cause of ectopic pregnancy. Lesions have been identified in the myometrium, and menorrhagia, spontaneous abortion, and premature labor have been attributed to infection. Overall, these data suggest that schistosomiasis is rarely a cause of male or female infertility, at least in West Africa.

This overview provides a discussion of the special concerns of sexually transmitted diseases (STDs) for women, particularly because of its asymptomatic character; screening; primary prevention; e.g., abstinence, selection of sexual partners restriction of sexual activities, use of barriers (condoms, vaginal spermicides, diaphragm in conjunction with spermicides), and vaccines; and the role of the gynecologist in StD prevention. Gonorrhea and chlamydial infection are usually asymptomatic STD infections in women; long term sequelae are pelvic inflammatory disease (PID), infertility, and pregnancy complications. There is an increased risk of cervical cancer. Infection is lifelong for herpes simplex virus (HSV) and HIV and malingering for chronic hepatitis B (HPB). Genital human papillomavirus (HPV) and HSV infections cannot be identified serologically. The fetus can be fatally or severely affected by STDs. Abstinence is the only effective prevention for STDs. Likelihood of infection may be reduced by limiting partners, but how partners are chosen and knowledge of infection is a more important determinant. Partners need to be asked about current symptoms, history of STDs, multiple partners, and history of known STD partners, as well as past history of homosexual activity, intravenous drug use, hemophilia, and previous exposure to high-risk persons for STDs. Visible genital warts or lesions, wartlike growths, ulcers, or rash need explanations. Avoidance of oral anal and digital anal activity reduces transmission of hepatitis A, giardiasis, amebiasis, and shigellosis. Any mechanical barrier that remains intact should reduce the risk of STD; barriers specifically covering the cervix are excellent. Condom use is effective when used as follows: 1) at the onset of sexual activity, 2) without petroleum jelly or baby oil on latex, 3) with care of fingernails which may tear holes, 4) with complete withdrawal of the penis before complete detumescence, and 5) with a withdrawal hold at the base of the penis. Spermicides, such as nonoxynol 9, are effective against STDs. Diaphragm use with spermicide may be effective because of the spermicide. There is a reduced risk of transmission of HSV or HPV to a partner. Vaccines are only available for hepatitis B. Obstetrics and gynecology residency training in STDs in unavailable in 4 out of 5 medical schools, and gynecologists are ethically obligated to accurately inform about STD diagnosis, treatment, and diagnosis.

Sexually transmitted diseases (STDs) are now the most common group of identifiable infectious diseases in many countries, especially among those ages 15-50 and in infants. Their control is important considering the high incidence of acute infections, complications and sequelae, their socioeconomic impact, and their role in increasing transmission of the human immunodeficiency virus (HIV). THe worldwide incidence of major bacterial and viral STDs is estimated to be over 125 million cases yearly. STDs are hyperendemic in many developing countries. However, in industrialized countries, the bacterial STDs such as syphilis, gonorrhea, chancroid declined from their peak during WW II until the late 1950s, increased during the 1960s and early 1970s, and have again decreased since that time. In the industrialized world, diseases due to Chlamydia trachomatis, genital herpes virus, human papillomaviruses, and HIV are now more significant than the classical bacterial ones; both groups remain major health problems in most developing countries. Infection rates are similar in both men and women, but women and infants bear the major burden of complications and serious sequelae. Infertility and ectopic pregnancy are often a result of pelvic inflammatory disease and are preventable. STDs in pregnant women can result in prematurity, stillbirth, and neonatal infections. In many areas, 1-5% of newborns are at risk of gonococcal ophthalmia neonatorum, a disease that blinds and congenital syphilis causes up to 25% of perinatal mortality. Genital and anal cancers (especially cervical cancer) are associated with viral STDs (genital human papillomavirus and herpes virus infections). Urethral stricture and infertility are frequent sequelae in men. (author's modified)

To study the effect of mycoplasmas and Chlamydia trachomatis infection on semen quality, these microorganisms were cultured from the semen and anterior urethra respectively, in a group of 175 infertile men suspected of a silent genital infection with a poor postcoital test. Chlamydia infection, but not mycoplasmas, was parodoxically more frequent in the apparently normal than oligotetratoasthenozoospermia patients. Mycoplasmas male infection, but not chlamydia, was more frequent in cases with female, mechanical, and/or organic infertility factors. Infection was unrelated to the accessory gland evaluation or sperm variables. However, seminal antisperm antibody activity was significantly increased in cases with any positive culture. By this local antibody increase, chlamydia and mycoplasmas may significantly reduce sperm egg penetration ability.

Samples for histological studies were taken from the genitalia of 14 bulls (five infected with Trypanosoma vivax, five with T. congolense and four uninfected control animals), slaughtered 12, 22 or 30 weeks post-infection. Infection with Y58 strain of T. vivax and strain 2295 of T. congolense caused various grades of lesions in the male reproductive organs, especially the testes and epididymides. T. congolense produced more severe degenerative changes than T. vivax. It is concluded that in long-standing cases, the result of trypanosome infection is either serious infertility or even sterility.

The reproductive anatomy, physiology, and breeding behavior of the llama is unique enough to make familiarity with it imperative. Female puberty averages 12 months, while many males are not reproductively functional until after 3 years. Proper management of a breeding pair or herd is necessary to maintain maximum reproductive performance. Proof of pregnancy is suggested by rejection of the male and may/should be confirmed by progesterone assay, rectal palpation, or ultrasound techniques. The postpartum female is notable for breeding back rapidly, with high pregnancy rates resulting. Both male and female factors enter into llama infertility, with each gender having significant incidence of reproductive anatomical abnormalities. Management as well as acquired infertility problems (heat factors, trauma, infection, neoplasia, and hormonal imbalances) contribute to the bulk of infertility cases investigated. Techniques used to diagnose infertility in llamas are quite comparable to the equine species; however, female body size and semen analysis in the male present significant challenges. The approach to therapy has been quite empirical to date, owing to lack of consistent problems and numbers to afford conclusive trials. Alterations of pregnancy include resorption, abortions, and stillbirths. Resorption between 30 to 60 days of gestation is reported regularly. Abortions caused by stress occur regularly. Infection abortions caused by leptospirosis, toxoplasmosis, and chlamydiosis are to be expected. Ponderosa pine-related abortions are suspected. In summary, I find use for a broad background in large animal theriogenology to apply to llama infertility. There no doubt are additional diagnostic techniques and therapeutic regimens that have application, and it is up to us all to keep good records and share the information.

Infections caused by Chlamydia trachomatis are the most common sexually transmitted diseases occurring in developed countries. Among women, chlamydia-mediated diseases include urethritis, cervicitis, endometritis, and salpingitis. Sequelae include infertility, pelvic pain, ectopic pregnancy, and perinatal infection. Aspects of epidemiology, pathogenesis, diagnosis, treatment, and prevention are discussed.

An investigation on the prevalence of Chlamydia trachomatis was carried out on 231 patients (115 men and 116 women, mean age 31.6 years) with genital non-gonococcal infection in order to study the role of this microorganism in infertility and/or sterility in the Italian population. One hundred and sixty-six apparently healthy subjects (108 men and 50 women, mean age 32.4) were also included as control for serological comparison only. Persons with gonococcal infection were excluded. ELISA method was chosen for the direct C. trachomatis examination of "scraping" samples. Serological investigations were carried out by means of the indirect immunofluorescence test for IgM and IgG determination as well as the immunoperoxidase assay for IgA antibodies. A direct C. trachomatis positive test was demonstrated in 27.8% of men vs. 11.2% in women (p less than 0.01) in the patient group. Anti-C. trachomatis IgG specific antibodies were present respectively at any serum dilution in 50.2% of patients vs. 47.6% of normal subjects respectively (p greater than 0.5). The low presence of C. trachomatis (19.5%) at the direct test contrasts with the higher percentage of anti-C. trachomatis positive patients (50.2%) in the same group suggesting that serological tests may be more useful than the direct test in demonstrating an active C. trachomatis infection provided that IgM, IgG and IgA specific antibodies be contemporaneously investigated.
