How Effective Is Neem Oil Killing Sperm?

It was discovered that crude extract destroys 100% of 1 million sperm in 20 seconds. Figure 1: Effect of different dosages of aqueous extract of tender neem leaf on percent motility of 1 million sperm after 20 seconds of exposure.

Does neem kill sperm in men?

Despite the fact that scientific study into neem is still in its early stages, it shows promise for a variety of health advantages, including blood sugar management, as well as hair, skin, teeth, liver, and kidney health.

May promote hair health

Azadirachtin, an active chemical found in neem seed extract, may help to battle parasites that damage hair and skin, such as lice. Azadirachtin functions by inhibiting parasite development and reproduction, as well as other cellular processes (9).

In a study on the effectiveness of a neem-based shampoo on head lice in youngsters, leaving the shampoo in their hair for 10 minutes killed the lice while being gentle on their skin (10, 11).

Because of its anti-inflammatory and antibacterial qualities, neem extract and nimbidin, a molecule found in neem oil, may be used to treat dandruff. Fungal growth on the scalp can cause dandruff and scalp inflammation (8, 12).

May boost dental and oral health

The antibacterial, anti-inflammatory, antioxidant, and immune-boosting qualities of neem may help to maintain good oral health. Despite the fact that more research is needed, studies show that neem can help treat gingivitis, periodontitis, and tooth decay (3).

Furthermore, test-tube studies suggest that neem may reduce plaque production by limiting bacteria’s ability to colonize the surface of your teeth (14).

Furthermore, neem mouthwash was found to be equally effective as chlorhexidine mouthwash — a heavy-duty prescription mouthwash — at reducing gum bleeding and plaque in a 21-day research involving 45 people with gingivitis (15).

May aid liver and kidney health

The antioxidant and anti-inflammatory qualities of neem may aid in the fight against oxidative stress, which may benefit liver and kidney health.

A accumulation of unstable chemicals known as free radicals causes oxidative stress. External sources increase the presence of free radicals, which your body naturally produces as a consequence of metabolism.

Some medications, such as cancer medications, pain relievers, and antipsychotics, can cause oxidative stress, which can lead to tissue damage in the liver and kidneys (16).

In a rat study, neem leaf extract was found to minimize liver damage caused by high-dose acetaminophen (17).

Another rat study found similar results, implying that neem extract reduced the damage to kidney tissue caused by chemotherapy (18).

May improve skin health

Fatty acids such as oleic, stearic, palmitic, and linoleic acids are abundant in neem seed oil. These fatty acids have been proven to have anti-inflammatory, antioxidant, and antibacterial effects, all of which are beneficial to skin health (19).

Keep in mind that while neem is used to cure psoriasis and eczema in Ayurvedic medicine (an Indian traditional healing method), there are few scientific studies to back up these claims (20).


Neem has been used to treat acne, minimize blemishes, and increase skin suppleness for centuries (21).

When neem oil is combined with solid lipid nanoparticles (SLNs), a new type of medication formulation that provides a stable release of active components, a test-tube study found that it can help with long-term acne treatment (21).

Ulcer and wound healing

According to animal research, neem leaf extract promotes wound healing by increasing the inflammatory response and the development of new blood vessels (8, 22).

In a 34-day case study conducted in 2013, using 100 mg of neem oil topically twice day treated chronic skin ulcers completely (23).

Six persons with intestinal ulcers were given 30 mg of neem extract orally twice daily in another research. Acid secretion had decreased dramatically after 10 days, and the ulcers had nearly fully healed after 10 weeks (24).

Antimalarial effects

Limonoids are active chemicals found in neem. In a mouse research, limonoids were found to be just as effective at targeting malaria-infected cells as chloroquine-based treatments (2, 25).

Some test-tube experiments, however, demonstrate that neem extract has little effect on malaria results (26).

Antifertility treatment

Because of its antifertility properties, neem has been proposed as a viable alternative to a vasectomy. A vasectomy is a surgical operation that sterilizes testicles by preventing sperm from being released.

According to animal research, neem can paralyze and destroy sperm with no long-term effects (2, 4, 27).

Diabetes management

According to several animal research, neem leaf extract could be a possibility for novel diabetic medicines (4, 5, 8).

Because neem extract may help revitalize cells that make insulin, a hormone that helps manage blood sugar, and lower blood sugar levels, it’s a promising treatment option (28).

Despite the fact that neem appears to have a wide range of therapeutic properties, the results are unclear because they are based on test-tube and animal research with few human investigations.

Does neem destroy sperm cells?

Is neem hot or cold in nature?

In general, neem is thought to be beneficial to the reproductive system, gastrointestinal tract, urinary tract, respiratory system, and circulatory system. 3 The following parts of the body have also been documented to benefit from neem. 4

  • It’s all about skin and blood. Neem is well-known for producing healthy skin and a radiant complexion. It has an extraordinarily cooling impact on the body, lowering excess heat that might manifest as skin blemishes, thanks in part to its bitter taste.
  • The immune system is the body’s defense mechanism. Its detoxifying properties make it an excellent herb for supporting a healthy immune system, particularly when it comes to removing ama (natural poisons) from the body.
  • Sugar levels in the blood The cleansing effects of neem on the body’s blood and circulation also aid in maintaining healthy blood sugar levels that are already within normal limits.
  • Gastrointestinal Tract It is critical to maintain a healthy intestinal environment. In the GI tract, neem decreases unnecessary heat and toxins.
  • Metabolism. The kapha-lowering effects of neem promote normal fat and water digestion and excretion, preventing water retention in the body.
  • Hair. Neem is great for cooling the scalp and aiding the growth of lustrous, smooth hair for people with excess pitta and heat trapped in the scalp and hair follicles.
  • Gums and teeth Neem is a powerful herb for maintaining healthy teeth and gums, as well as supporting overall oral hygiene.

Neem in Ayurveda

The effects of neem on the doshas are summarized here. If you’re unsure about your dosha, we recommend taking our free dosha quiz.

  • Neem is a Pitta-balancing herb. Neem has a bitter flavor, which provides it a strong cooling effect (virya). This cooling effect, combined with its ability to maintain healthy blood, aids in pitta equilibrium, especially when the rakta dhatu is hot (the blood). 5
  • Neem is a Kapha-balancing herb. Because of its light and dry properties, neem can also help to balance kapha. The kapha-lowering effects of neem promote normal fat and water digestion and excretion, preventing water retention in the body.
  • Neem has the potential to aggravate Vata. Vata is aggravated by the cold, light, and dry properties of neem. As a result, neem is frequently used in conjunction with other herbs to help balance out its vata-inducing properties.

Because of neem’s strong energetics, it’s usually best to combine it with other herbs when taking it internally, utilize it for a short period of time, or take it under the supervision of a practitioner.

Other Ayurvedic Uses

In Ayurveda, neem is said to promote healthy metabolism by igniting agni, or the digestive fire, within the meda dhatu (adipose tissue layer). It’s commonly taken internally to keep the liver, pancreas, and digestive tract in good working order.

The bitterness of neem also enhances taste, which is essential for good digestion.
