The fimbriae (singular fimbria) is a fringe of densely ciliated tissue projections of approximately 1 mm in width around the distal tubal opening, oriented towards the ovary. [12] They are attached to the ends of the infundibulum, extending from its inner circumference, and muscular wall. [12] The cilia beat towards the fallopian tube. [12]
The pampiniform plexus (from Latin pampinus 'tendril' and forma 'form') is a venous plexus – a network of many small veins found in the human male spermatic cord, and the suspensory ligament of the ovary. In the male, it is formed by the union of multiple testicular veins from the back of the testis and tributaries from the epididymis.
One difference between the glans penis and the glans clitoridis is that the glans clitoridis packs nerve endings into a volume only about one-tenth the size of the glans penis. Therefore, the glans clitoridis has greater variability in cutaneous corpuscular receptor density (1-14 per 100× high-powered field) compared with the glans penis (1-3 ...

The ovary of teleosts is also often hollow, but in this case, the eggs are shed into the cavity, which opens into the oviduct. [52] Certain nematodes of the genus Philometra are parasitic in the ovary of marine fishes and can be spectacular, with females as long as 40 cm (16 in), coiled in the ovary of a fish half this length. [54]
A study by Swan et al. determined that the AGD is linked to fertility in males, and penis size. [3] Males with a short AGD (lower than the median around 52 mm (2 in)) have seven times the chance of being sub-fertile as those with a longer AGD. It is linked to both semen volume and sperm count. [8]
The “spacing effect” refers to a phenomenon whereby learning, or the creation of a memory, occurs more effectively when information, or exposure to a stimulus, is spaced out.
A second study by the same group showed significant variations in size and shape between the vaginas of women of different ethnic groups. [4] Both studies showed a wide range of vaginal shapes, described by the researchers as "Parallel sided, conical, heart, [...] slug" [3] and "pumpkin seed" [4] shapes. Barnhart et al., however, were not able ...
