A major limitation in the application of assisted reproductive technologies in sheep arises from the inability to easily traverse the uterine cervix. The cervix of the non-pregnant ewe is a narrow and rigid structure, with 5—7 spiral folds and crypts that block its lumen. The first two folds closest to the vagina appear to be the greatest obstacle for the instrument insertion into the sheep cervix. Therefore, the dilation of the distal part of the cervix could provide the conformational change necessary to perform non-invasive transcervical procedures.
Induction of cervical dilation for transcervical embryo transfer in ewes
Objective: To determine the effect of different cervical dilators on cervical dilation and reproductive performance of fat-tailed ewes. In experiment 2, artificial insemination was applied for evaluation of reproductive performance in experimental groups. In addition, the lowest cervical dilation was observed in control group. Conclusions: Oxytocin treatment alone or with estradiol could be used as a suitable dilator for improving reproductive efficiency during artificial insemination in fat-tailed ewes.
For example, it may rise alongside ovulation to prepare for conception or lower to allow menstrual tissue to pass through the vagina. Each change in position is tied to a particular phase in your menstrual cycle or other hormonal change, such as pregnancy. Checking the position and texture of your cervix — as well as any cervical mucus — can help you gauge where you are in your cycle. Your cervix is pretty deep inside your body.
