Semen is a bodily fluid that is secreted by the gonads of male animals. It contains spermatozoa and fructose and other enzymes that help the sperm to survive and facilitate successful fertilization. During the process of ejaculation, the semen is ejaculated from the seminal vesicle in the pelvis, which is where it is produced.
Amount of semen per ejaculate
The volume of semen released per ejaculate varies. It is estimated that an average of around 3.4 milliliters (mL) is ejaculated at one time. The amount ejaculated can be as high as 4.99 mL or as low as 2.3 mL.
If there is a prolonged gap between ejaculations, the number of sperm in the semen increases, but there is no overall increase in the semen.
Composition of semen
Semen passes through the ejaculatory ducts and mixes with fluids from the seminal vesicles, the prostate, and the bulbourethral glands. The seminal vesicles produce a viscous, fructose-rich fluid. This forms around 65-70% of the semen base.
The white color of the semen is due to secretion from the prostate glands containing enzymes, citric acid, lipids, and acid phosphatase which, taken together, forms around 25-30% of the semen base. At each ejaculation, around 200-500 million spermatozoa are released by the testes. This forms about 2-5% of the semen composition.
The bulbourethral glands produce a clear secretion that helps in the mobility of the sperm cells in the vagina and cervix. In addition, this clear secretion reduces the thickness of the channel that the sperm cells swim through and adds a cohesive, jelly-like consistency to the semen. The glands’ secretion contributes less than 1% to the overall semen composition.
Semen also contains more than 50 different compounds including hormones, endorphins, neurotransmitters, and immunosuppressants. Other substances present in the semen include:
- Fructose
- Ascorbic acid
- Zinc
- Cholesterol
- Protein
- Calcium
- Chlorine
- Blood group antigens
- Citric acid
- DNA
- Magnesium
- Vitamin B12
- Phosphorus
- Sodium
- Potassium
- Uric acid
- Lactic acid
- Nitrogen
- Vitamin C
Semen also consists of a variety of proteins that have antimicrobial activity against bacteria, viruses, and fungi.
Possible beneficial effects of consumption of semen
Also present in the semen are mood-enhancing compounds such as cortisol, estrone, oxytocin, thyrotropin-releasing hormone, prolactin, melatonin, and serotonin. For this reason, scientists have begun studying the health benefits of semen intake, both orally and vaginally. Some of the studies into the effects of swallowing semen are described here.
Pregnancy
In a Dutch study of women who engaged in oral sex and swallowed the semen, the researchers found that swallowing semen was associated with a lower risk of preeclampsia. One hypothesis for this is that substances in the semen adapt the mother’s immune system so that it accepts foreign proteins present in sperm, as well as in the placenta and fetus. This maintains the blood pressure at a low level and thereby reduces the preeclampsia risk.
Research has also shown that some women are infertile or miscarry due to the presence of antibodies that destroy the proteins or antigens present in their partner’s semen. Having oral sex and swallowing the semen of the partner may help make the pregnancy safer and more successful as the woman is swallowing her partner’s antigens.
Work carried out by reproductive expert and psychologist Gordon Gallup from the State University of New York (SUNY) at Albany suggests that swallowing semen could provide a cure for morning sickness. Gordon hypothesizes that pregnant women vomit as a result of their bodies rejecting genetic material in the sperm as a foreign substance, but that by swallowing and ingesting the sperm of the baby’s father, they can build up immunity.
Ovulation
In a study conducted by researchers from the University of Saskatchewan, a protein in semen was found to act on the female brain to induce ovulation. That protein is the same molecule that controls the growth, maintenance, and survival of neurons. The findings suggest that semen may work as a signaling hormone that acts via the hypothalamus and pituitary gland of the female brain, which triggers the release of other hormones involved in prompting ovulation.
Hair health
Some studies have shown that semen extracted from bulls rejuvenates damaged hair. Semen has been found to contain many proteins that may complement the protein present in hair molecules.
Possible disadvantages of consumption of semen
Semen can contain several viruses that may be transmitted via bodily fluids from an infected man. Some common examples of such sexually transmitted infections (STIs) include the human immunodeficiency virus (HIV), hepatitis B and C, herpes, and chlamydia.
The risk of transmitting an STI through oral sex is higher if there is an open sore in the mouth or if a person has gingivitis and bleeding gums. According to the United States Centers for Disease Control and Prevention, hepatitis B can also be transmitted through contact with infected semen if an open sore is present in the mouth.
Human papilloma virus
The human papillomavirus has emerged as a serious concern in relation to oral sex. This virus can cause cervical cancer, anal cancer, and the development of other growths such as genital warts. In 2013, some research suggested the virus can even cause lung cancer.
In 2010, a multinational review published in the British Medical Journal demonstrated that the incidence of oropharyngeal squamous cell carcinoma is on the rise in Western countries and that this increase seems to be linked to HPV, particularly the HPV-16 strain. The article implied that HPV is spread through sex, but in particular, oral sex.
Chlamydia and gonorrhea
The transmission of chlamydia and gonorrhea through oral sex has also become a concern. In May 2011, a study of female commercial sex workers showed that one in 25 of the workers had chlamydia in their throats. In addition, one in 50 of the sex workers had gonorrhea in their throats.
Cultural practices and beliefs
Some cultures believe that semen has special properties of masculinity. The idea of semen being associated with masculinity was prevalent in ancient Greece when Aristotle considered semen to be very important.
To this end, Aristotle said that a connection existed between blood and semen, in that semen was produced from blood using body heat. Aristotle also believed that too early initiation of sexual activity may mean a loss of semen and, subsequently, a loss of valuable and much-needed nourishment.
In Papua New Guinea, some communities believe that semen provides sexual maturation to the younger men of the tribe. The tribes believe that the semen of older men can bestow manliness and wisdom to the younger men and for this reason, the younger men fellate their elders in order to receive their authority and powers.
In ancient eastern cultures, gemstones are believed to be drops of divine semen. Chinese believe jade is the dried semen of the celestial dragon.

Fascynujące nowe badanie opublikowane w czasopiśmie Frontiers in Psychology ujawniło intrygujące szczegóły dotyczące roli wzrostu w preferencjach romantycznych. Badanie, w którym uczestniczyli uczestnicy z kilku krajów, dostarcza nowych spostrzeżeń na temat tego, dlaczego mężczyźni wolą niższe kobiety, zwłaszcza w pewnych kontekstach relacji, i dlaczego kobiety zazwyczaj skłaniają się ku wyższym mężczyznom. Odkrycia sugerują również, że wzrost odgrywa bardziej złożoną rolę w naszych wyborach romantycznych, niż moglibyśmy przypuszczać.
Niniejszy artykuł zagłębia się w wyniki badania i analizuje przyczyny preferencji dotyczących wzrostu w związkach romantycznych, ze szczególnym uwzględnieniem tego, jak te preferencje różnią się w różnych typach związków.
The Study: How Height Influences Romantic Preferences
The study, which involved 536 participants from Canada, Cuba, Norway, and the United States, presented minimalist drawings of men and women of various heights. Participants were asked to select their ideal partner’s height for short-term and long-term relationships.
The results highlighted a fascinating trend:
-
Men preferred women who were slightly shorter than the average female height in their country, with an average preference for women about 2.5 cm shorter.
-
Women, on the other hand, preferred men who were taller than the average male height, with an average preference for men about 2.3 cm taller.
This preference for height was not only seen across different countries but was also consistent among individuals of various ages and backgrounds.
Men’s Preference for Shorter Women in Short-Term Relationships
One of the most interesting findings from the study is that men’s preferences for women’s height varied depending on the context of the relationship. Men tended to prefer even shorter women for short-term relationships than they did for long-term ones. This suggests that height is not a trivial matter in romantic attraction but rather plays a more nuanced role depending on the type of relationship men are looking for.
For long-term relationships, men still preferred women who were slightly shorter than them but were more flexible when it came to the height difference. However, when the relationship was expected to be short-term, the preference for much shorter women seemed to grow. This may be due to various factors, including cultural influences or biological instincts related to reproduction.
Women’s Consistent Preference for Taller Men
In contrast, women’s height preferences were less variable. Women consistently preferred taller men across both short-term and long-term relationship scenarios. On average, women wanted a partner who was approximately 2.3 cm taller than the average male height in their respective country.
This preference for taller men has been observed in previous studies and may be tied to biological factors and evolutionary psychology. Throughout history, taller men have been associated with strength and protection, qualities that many cultures have valued in long-term partners. These traits may influence women’s attraction to height, regardless of the relationship’s duration.
Assortative Mating: The Preference for Similar Heights
The study also uncovered a fascinating phenomenon known as assortative mating, which refers to the tendency of individuals to choose partners who are similar in certain traits, such as height. The findings showed that taller individuals tended to prefer taller partners, while shorter individuals preferred shorter partners.
This pattern indicates that people are often drawn to individuals who share similar physical characteristics, including height. Assortative mating is thought to be influenced by both biological and cultural factors. For example, individuals of similar height may be more likely to feel comfortable and compatible with each other, as they share a similar physical presence.
The Impact of Cultural and Biological Factors on Height Preferences
While the study provides interesting insights into height preferences, it also raises important questions about how cultural and biological factors influence romantic choices. Height preferences may vary across different societies, with some cultures placing more importance on physical stature than others. Additionally, individuals in different cultures may have varying views on gender roles, which could influence their attraction to taller or shorter partners.
Biologically, the preference for taller men and shorter women may be tied to evolutionary psychology. In many species, physical size and stature are linked to strength, protection, and the ability to provide resources. These traits may have influenced human attraction preferences in ways that still manifest today.
Limitations of the Study
While the study provides valuable insights, it’s important to note that it has certain limitations. The study relied on minimalist drawings of individuals, which may not fully reflect the complexities of real-life interactions. Participants did not meet or interact with the individuals in the drawings, and height preferences may change when there are additional factors involved, such as personality, interests, and chemistry.
Furthermore, height preferences may be influenced by personal experiences or societal influences, which were not fully accounted for in the study. People’s preferences may vary based on their personal history or the media they consume, which often portrays certain ideals of beauty and attraction.
Height Preferences: A Reflection of Attraction and Compatibility
The study’s findings suggest that height preferences are not just superficial traits but can be deeply rooted in biological instincts and cultural conditioning. While some may argue that height should not matter in romantic attraction, these preferences reveal that our choices are influenced by a complex mix of evolutionary psychology, cultural norms, and personal experiences.
For men, the preference for shorter women may be tied to an instinctual desire for femininity, protection, and a sense of nurturing, while women’s preference for taller men may stem from historical associations with strength and security. However, it’s important to recognize that height is just one factor in the vast array of attraction and compatibility that shapes relationships.
Conclusion: The Complexity of Attraction and Height Preferences
This study sheds light on the fascinating relationship between height and romantic preferences. While the results are not necessarily groundbreaking, they provide important insights into why certain height patterns emerge in romantic choices. For men, a preference for shorter women seems to be more pronounced in short-term relationships, while women consistently prefer taller men, regardless of the relationship type. The phenomenon of assortative mating further complicates this picture, showing that individuals often choose partners of similar height.
Ultimately, it’s clear that height plays a significant role in romantic attraction, but it’s important to remember that attraction is a highly individualized experience. There is no universal standard for love, and personal preferences vary widely depending on individual desires, experiences, and cultural influences.
