Endometriotic ovarian cysts negatively affect the rate of spontaneous ovulation.
BACKGROUND A growing body of evidence suggests that ovarian reserve is damaged after excision of ovarian endometriomas. However, it may not be excluded that gonadal damage is at least partly caused by the very presence of an endometrioma per se, thus preceding surgery. To clarify this aspect, we set up a prospective study in women with monolateral endometriomas in order to assess the rate of ov...
متن کاملConception Rate, Farrowing Rate and Litter Size after Intrauterine Insemination with Cryopreserved Boar Semen in Spontaneous and Induced Ovulation Sows
Introduction The procedure for artificial insemination (AI) in pigs using cryopreserved semen involves the deposition of a high number of cryopreserved spermatozoa (5-6 x10 cells) in a large volume of diluent (80-100 ml) into the cervix. Despite inseminating with this high sperm number, low fertility levels are usually obtained (about 20-30% conception and farrowing rates and 2-3 total piglets ...

15 صفحه اولMeiosis and Inhibition of Ovulation in Mouse Eggs Treated with Actinomycin D
Barros and Austin (1) have reported on the inhibition of ovulation in the golden hamster by parenteral actinomycin D (AMD). During studies aimed at characterising the meiotic chromosome damage induced by various inhibitors of DNA, RNA, and protein, the author has made some observations in vitro and in vivo on the effects of AMD on female mouse meiosis . These data extend the information of Barr...
متن کاملCleavage rate of mouse embryos in vivo and in vitro.
Mouse embryos (Q strain) developing in vivo from the 2-cell to the blastocyst stage showed a constant cell doubling time of about 10 h. Embryos cultured in vitro over the same period showed a rate of cleavage which was initially almost as great as in the reproductive tract, but subsequently declined to give a doubling time of about 24 h. Addition of oestrogen to the culture medium increased the...
