Effect of neuraminidase and follicular fluid upon the surface characteristics of human spermatozoa. Despite that, available evidence and accumulated clinical experience support the notion that any adverse antiestrogenic effect presents a significant obstacle for a very large majority of women treated with ovulation induction drugs. This finding could be interesting in fertility programs or as a model to evaluate the capacitation process. This strategy is particularly effective for overcoming cellular immune responses. As a result, water movement from inside to outside cellular compartments is decreased, leading a more viscous and less watery mucus which harms sperm transport. Influence of random factors and two different staining procedures on computer-assisted sperm head morphometry in bulls.
PDC can also contribute to membrane stability by inhibiting the activity of phospholipase A 2 Manjunath et al.
Importance of sperm morphology during sperm transport and fertilization in mammals
These findings may suggest that tubal fluid potentiates the motility and viability of spermatozoa, thus enhancing the chances of fertilization. The greatest barrier to sperm penetration of cervical mucus is at its border, because here the mucus microarchitecture is more compact Yudin et al. Gomendio and Roldan 63 found that spermatozoa with elongated heads swam faster and that the effect of head shape upon sperm hydrodynamics was considerable. Morphometry of porcine spermatozoa and its functional significance in relation with the motility parameters in fresh semen. The sequential effects of human cervical mucus, oviductal fluid, and follicular fluid on sperm function. Since boar semen is deposited directly into the uterine cavity, the uterus is exposed to the full amount of estrogens in the semen. Blaustein's Pathology of the Female Genital Tract, p
