Over the past 50 years, a decline in the quality of semen has been observed, possibly resulting in a reduction in male fertility. Among the factors affecting semen quality, exposure to drugs is of particular importance. It is known that drugs can be transported to the seminal plasma, which is made up of secretions from the various accessory genital glands. There is evidence that many drugs enter the male genitourinary tract by an ion-trapping process. Lipid solubility and the degree of ionisation of the drug, which depend on the pH of plasma and seminal fluid, are important factors in this process. To date, few studies have been conducted on this topic. Pharmacokinetic evaluation of the fluids of the male accessory gland have been performed in the case of chloroquine and caffeine only, while the effects of mesalazine 5-aminosalicylic acid , sulfasalazine, salicylate, propranolol, diltiazem, flunarizine, verapamil, caffeine and nicotine on sperm physiology and morphology have been examined.

J Exp Biol 1 August ; 15 : How do sperm find their way to the egg before fertilization? Heaven knows that from the sperm's perspective this is not a trivial question, as finding the egg is like looking for a needle in a haystack. To successfully locate the egg, sperm have to possess some navigation system. In metazoan organisms,sperm navigate by chemotaxis, moving along a concentration gradient of an attractant released by the egg. In , a large mammalian gene family was described that encodes approximately different odorant receptors, mostly expressed in the cilia of olfactory receptor neurons. However, several distinct odorant receptors have also been found to be expressed either predominantly or exclusively in sperm flagella. Since the flagellum provides the propulsive force for sperm locomotion, it was speculated that these testicular odorant receptors are directly involved in navigating the sperm towards the egg. In a recent Science paper, Marc Spehr and his colleagues investigated a previously undescribed testicular odorant receptor, termed hOR, in order to uncover its role in human sperm physiology. By combining molecular biology,pharmacological studies and behavioral assays, they were able to demonstrate for the first time that a testicular odorant receptor directly functions in sperm chemotaxis. They expressed the recombinant receptor protein in human embryonic kidney cells, treated the cells with a complex mixture of odorants and measured the receptor-induced calcium release. By subdividing the mixture into smaller fractions, they were able to identify the active ligand. They also tested the cells' responses to related substances and found that a broad spectrum of substances, including bourgeonal, activated the receptor. After finding active odorants, Hans Hatt's team wanted to see how their receptor functioned in live human sperm.

To date, few studies have been conducted on this topic, sperm snorting. The young woman says she wondered why the thief took her semen jar and was astonished when the sheriff deputies told her he had snorted it.

After class last thursday , Jessica invited invited me to her house to perform fellatio on me and then snort my cumcaine via her nostrils. I five-finger discounted some jockstraps from the cadet locker-room in the gym, and now I'm gonna snort some cumcaine. It's when excess jizz is snorted like Cocaine powder. Harry: My my.

One such field is male infertility where microfluidic technologies are enabling optimization of sperm sample preparation and analysis. In this chapter we review how microfluidic technology has been used for sperm quantification, sperm quality analysis, and sperm manipulation and isolation with subsequent use of the purified sperm population for treatment of male infertility. We then review microfluidic-based systems that facilitate non-invasive identification and sorting of viable sperm for in vitro fertilization. Finally, we explore commercialization challenges associated with microfluidic sperm sorting systems and provide suggestions and future directions to best overcome them. Microfluidics is the science and technology of accurate manipulation of small amounts of fluids, which is typically done in microchannels with dimensions of a few hundred micrometers 1.

Sperm snorting

Watery semen may be a temporary issue caused by frequent ejaculation or a zinc deficiency. In some cases, water semen can result from a low sperm count due to infection or another cause. Semen is the fluid released through the male urethra during ejaculation. It carries sperm and fluids from the prostate gland and other male reproductive organs. Normally, semen is a thick, whitish liquid. However, several conditions can change the color and consistency of semen. Watery semen can be a sign of low sperm count, indicating possible fertility problems. Ejaculating thin, clear semen may also be a temporary condition with no serious health concerns. One of the most common causes of watery semen is low sperm count. This is also known as oligospermia.

The denaturation was then stopped and proteins were removed by transferring the slides to a tray with neutralizing and lysing solution 0. In the last five years the percentage of ketamine users has rapidly grown. Therefore, it may be advisable to include, in the processes of drug development, pharmacokinetic evaluation of a drug in the semen and analysis of standard microscopic parameters of the semen.
