Reproductive tracts from 105 anoestrous Romney ewes were examined histologically. Twenty animals served as controls, 10 received pregnant mare serum (PMS), and 10 mere given progesterone injections followed by PMS. Different amounts of progesterone alone mere administered during 4 days to the remainder. Sections were cut from tissues of the vagina, cervix, uterus, and three regions of the fallopian tubes. The findings in the control ewes in the present investigation agreed in general with those reported by earlier workers, with the exception of the fallopian tubes in the anoestrous ewe, for which no data were available in the literature. Apparently the upper part of the genital tract recedes in anoestrus to a condition not observed at any point in the breeding season. The influence of progesterone injections was most pronounced on the uterus, but was seen to a lesser degree in the cervix. Neither the vagina nor the fallopian tubes exhibited marked changes as a result of progesterone administration but both organs reflected slightly the ovulations which had been induced.

ABSTRACT Gynecological and obstetrical infectious diseases are an important component of women's health. A system approach to gynecological and obstetrical infection helps unify and classify microbial etiology and pathogenesis within a clinical anatomical framework of lower and upper genital tract syndromes. The reproductive system of women includes the vulva, vagina, cervix, uterus, fallopian tubes and ovaries. During pregnancy, additional tissues include the chorioamnion and placenta together with the fetus and amniotic fluid. We review in two parts reproductive system infection syndromes in women using selected research results to illustrate the clinical utility of the system approach in terms of diagnosis, treatment and prevention. We conclude that a reproductive system perspective will lead to improvements in understanding, management and prevention of these diseases.

Observations were made on the distribution of spermatozoa in the genital tract of the ewe at 15 min, and at 4, 24, and 48 hr after coitus. A total of 60 animals was used. The number of spermatozoa in t,he cervix wa.s highest at 15 min and in the uterus the maximum number was recorded at 24 hr. Stress decreased the number of spermatozoa present in the fallopian tubes at 15 min after coitus but did not influence the transport of spermatozoa into the cervix, the distribution of spermatozoa within the genital tract at 4, 24, and 48 hI', the number of spermatozoa on the zona pellucida of recovered eggs, or the proportion of eggs fertilized.

Background: Fallopian tubes are common surgical specimen in the pathology laboratory; still there is a lack of data to describe the frequency of various histological fi ndings. The aim and objectives of this study was to describe the various histopathological fi ndings of fallopian tubes. Materials and Methods: Two thousand fi ve hundred and seventy fi ve cases where fallopian tubes were removed either separately or along with other female genital tract organs were studied retrospectively and their histopathological fi ndings documented. Results: Ectopic pregnancy comprised maximum number of cases closely followed by salpingitis. Primary neoplastic lesions were rare as compared to secondary malignancies. Serial sections of fallopian tube and sections from representative areas are essential for a pathologist so that the diagnosis of these pathological entities is not missed. Conclusion: Though the fallopian tubes remain unremarkable in majority of the surgical pathological specimens, it must be subjected for histopathological examination to demonstrate the pathological lesions.

Large Ulcer

Genital tuberculosis (TB) in women is a chronic disease with low-grade symptoms. Genital tract tuberculosis is usually secondary to extragenital TB. The fallopian tubes are most commonly affected, and along with endometrial involvement, it causes infertility in such patients. Involvement of the cervix and the vulva is very rare. We present one such rare case of vulvar tuberculosis presented with a large ulcer diagnosed on histopathology and treated with antitubercular chemotherapy.

Sixteen ewes were drawn from each of two ewe flocks, one of which had grazed on oestrogenic pastures for annual periods over the previous 5 years ("clover" treatment) while the other grazed on green oats ("oats" treatment). Fertility of ewes on the clover treatment had decreased progressively, whereas in those on the oats treatment it had remained high. Oestrous ewes were allocated alternately to receive either two or eight services then killed 24 hr post coitus and the numbers of sperm in the cervix, uterus, and fallopian tubes determined. There was no difference in ovarian activity between the two groups; however, highly significant differences were found in the numbers of sperm recovered from the cervix, uterus, and fallopian tubes. Average sperm numbers per fallopian tube were 17,160 and 350 for ewes on the oats and clover treatments respectively. In addition to the reduction in sperm numbers, both the percentage of motile sperm flushed from the cervix and the proportion of recovered ova with sperm attached to the zona pellucida were lower in ewes on the clover treatment. The results suggest that primary failure of sperm transport in ewes on the clover treatment occurred when sperm did not enter the cervix in adequate numbers following service. The significance of these observations in relation to possible causal mechanisms is discussed.

The distribution of spermatozoa in the genital tract was determined in ewes killed 4 hr or 24 hr after cervical insemination with 100 million live spermatozoa from either freshly ejaculated or deep.frozen ram semen. At 4 hr, greater numbers of spermatozoa were present in the cervices, uteri, and fallopian tubes in ewes inseminated with fresh semen than in ewes inseminated with frozen semen. At 24 hr, the numbers of spermatozoa in the uteri and fallopian tubes of ewes inseminated with fresh semen had increased relative to the numbers at 4 hr but no spermatozoa were present in the uterus and fallopian tubes in ewes inseminated with frozen semen.

Endometriosis is a chronic hormone-dependent progressive disease characterized by the presence of ectopic endometrioid tissue. Most often, endometriosis affects the ovaries, fallopian tubes and the abdominal cavity, but endometrioid foci are also found in the intestines, heart, lungs, skin and other atypical localizations. This article presents a clinical case of retrocervical endometriosis diagnosed based on the results of pathological and histological examination. It is important to note the complexity of the differential diagnosis of this form of endometriosis due to secondary changes in the area of the colon and the absence of characteristic clinical manifestations.

The Difference

A series of studies was conducted in 1968 and 1969 to compare fertilization rates, return rate, and sperm distribution in the genital tract in Bungaree and Peppin Merino ewes. Differences in lambing rates of the two ewe strains were demonstrated, but there was no major difference in fertilization rate in either year. A significantly higher proportion of Bungaree ewes had less than 1000 sperm in the fallopian tubes 24 hours after service, but there were no significant differences in any other character examined. Contrary to an earlier report, fertilization failure is unlikely to have been a major cause of a difference in the fertility of the two strains in the two years, and embryonic loss is likely to have made a significant contribution to the difference in their fertility.
