The purpose of the present study was to investigate whether the electrical resistance values of the cervical mucus and/or blood οestradiol-17β and progesterone concentrations at mating, after oestrous synchronisation during the anoestrous or oestrous period in ewes, are related to fertility. Oestrus was induced by medroxyprogesterone acetate-impregnated intravaginal sponges (Veramix, Upjohn, US...

Human tissue kallikrein-related peptidases (KLKs) are 15 hormonally regulated genes on chromosome 19q13.4 encoding secreted serine proteases. Many KLKs are expressed throughout the female reproductive system and found in cervico-vaginal fluid (CVF). Immunohistochemistry was performed to determine KLK localization in the female reproductive system (fallopian tube, endometrium, cervix and vagina ...

Motility is the feature that allows spermatozoa to actively reach and penetrate the female gamete during fertilization. When this function is altered, and especially decreased, troubles in conceiving may occur. In this study, we demonstrated that treating fertile women with myo-inositol (MI) vaginal suppositories ameliorated their partners' sperm motility and also positively affected their conc...

Many biological materials such as cervical mucus and collagen gel possess a fibrous micro-structure. This micro-structure affects the emergent mechanical properties of material, hence functional behaviour system. We consider canonical problem stretching thin sheet transversely-isotropic viscous fluid simplified version spinnbarkeit test for mucus. propose novel solution to model constructed by ...

The study evaluated the effect of extenders and sperm concentration on migration efficiency Malabari buck spermatozoa in bovine cervical mucus. Fresh semen ejaculates collected six different days from three adult healthy bucks were pooled divided into four groups based extender used (tris-egg yolk-based or liposome-based extender) rate extension (200 400 million motile per 0.5 mL) (n=6 group) s...

Cyclic variations in the quality of cervical mucus were evaluated in the monkey. A characteristic pattern was observed. On the day before ovulation maximal fern production was noted, with a dramatic regression in fern pattern in the subsequent day. A consistent correlation with changes in vaginal cytology was not observed. Daily examination of fern pattern provides a reliable index for ovulatio...
