“…Maillo and others40 reported that early embryos (day 3) were able to avoid maternal immune response due to a crosstalk between them and the oviduct. Moreover, goats affected by hydrosalpinx presented histological alterations in oviduct and also in endometrial epithelium and glands of uterine horns 12. Altogether, these data lead us to reflect that goats affected by HD may have some disturbance in embryo–oviduct crosstalk, impairing embryo development.…”

“…For instance, long ovarian cystic condition may change uterus immunity and environment leading to fluid accumulation and eventually bacterial infection. Souza and others9 and Maia and others12 revealed respectively the occurrence of ovarian follicular cysts and hydrosalpinx simultaneously to HD. These facts lead us to speculate that HD may be associated with ovarian or oviductal disorders, further increasing the chance of temporary or permanent infertility.…”

BackgroundReproductive efficiency after hydrometra (HD) treatment is usually unsatisfactory.MethodsTo identify mechanisms involved in low reproductive efficiency of HD-treated goats, pluriparous dairy goats treated for HD (n=10, HD) or with no reproductive disorders (n=11, control: CONT) were induced to oestrus and superovulated. Goats were mated with fertile bucks and seven days after oestrus, non-surgical embryo recovery was performed. Embryos were evaluated and gene expression was performed.ResultsThere were no differences (P>0.05) in sexual behaviour parameters, superovulation response, mean number of retrieved structures and viable embryos between groups; although embryo recovery rate was higher (P=0.01) in CONT group. Structures in delayed stage (8–16 cells) were more frequent (P<0.05) in HD (29 vs 1 per cent) goats, as well as the percentage of advanced embryos was greater (P<0.05) for CONT (59.3 vs 33.3 per cent) goats. However, the expression of genes related to apoptosis (BAX and Bcl-2), trophectoderm differentiation (CDX2) and pluripotency maintenance (NANOG) was not affected (P>0.05) in embryos that reached the morulae and blastocyst stages.ConclusionAlthough the HD embryos that developed to morula and blastocyst stages showed no change in the expression of genes related to their quality and implantation capacity, overall, embryo development was impaired in HD-treated goats.

“…The occurrence of hydrosalpinx in goats is low, ranging from 0.2 to 1.1% (AL-BAGGAL et al, 1993;MAIA et al, 2018a) and can be associated with microorganisms (BEENA et al, 2017) or hydrometra (MAIA et al, 2018b). Moreover, during the ultrasound evaluation of the doe # 1, the hypoechoic heterogonous content is suggestive of salpingitis, but histopathological diagnosis was compatible with hydrosalpinx.…”

Objetivou-se descrever os distúrbios reprodutivos associados à infecção experimental por Toxoplasma gondii através da inseminação artificial com sêmen contaminado em quatro cabras no estágio crônico da infecção. As características do trato reprodutor foram avaliadas através de ultrassonografia transretal, visando o diagnóstico gestacional ou de desordens reprodutivas, após a infecção experimental. Ao final do experimento, os animais foram necropsiados e avaliações histopatológicas e PCR foram realizados. Dentre os animais infectados que exibiram mortalidade embrionária, duas apresentaram anestro e duas apresentaram repetição de estro, sendo que destas uma apresentou intervalos entre estros reduzido (sete dias) e outra em intervalo regular (21 dias). Todavia, ambas foram submetidas a monta natural durante os estros naturais subsequentes e não foi confirmada gestação até o final do experimento (90 dias). Duas cabras exibiram alterações nos exames de ultrassonografia, sendo identificadas um cisto ovariano, e uma hidrossalpinge, ambas confirmadas no exame post-mortem. As principais lesões microscópicas nesse grupo foram infiltração neutrofílica dos pulmões, glomerulonefrite intersticial e infiltração neutrofílica do fígado. O DNA de T. gondii foi encontrado nos órgãos (coração e cérebro) de três cabras. Em conclusão, cabras infectadas com sêmen contendo T. gondii no momento da inseminação artificial apresentam distúrbios reprodutivos na fase crônica da infecção que podem estar associados à toxoplasmose.
