The story starts with couples who had been trying for years.

For couples who did everything right, it has been painful and somewhat confusing...

Because children are supposed to come.

And no matter how many cycles they track, the good news never comes.

For years, everyone pointed at the usual suspects.

Some blamed her age...
Others blamed stress...
And many assumed it simply was not written yet.

But behind the scenes, researchers were finding something different.

They found that in about half of these couples, the problem was not on her side at all.

But on his, in a way most men have never been told about.

Here is what researchers found when they finally looked at the men.

Modern men are making weaker sperm every year

Sperm counts have fallen by more than half since 1973

The drop is getting faster with every decade

57,000 men, 53 countries

About half of all fertility problems involve the man

And when researchers looked for the cause, the same list kept coming back:

Heat from a laptop on the lap or a phone in the front pocket

Sitting at a desk for most of the day

Tobacco smoke from cigarettes or shisha

Fast food, fried food and sugar

Too little sleep and too much stress

Plastic chemicals in food and drink

In the 57,000 men they studied, across 53 countries, sperm counts fell in every region.

And the damage was not happening at conception. It was happening in the 74 days before, while the sperm was still being built.

This is not one man's problem, because it is happening to men everywhere at the same time.

If the damage is on his side, can anything undo it?

In 2014, a team of doctors set out to answer exactly that.

Effects of Nigella sativa L. seed oil on abnormal semen quality in infertile men: a randomized, double blind, placebo controlled clinical trial

Kolahdooz M, Nasri S, Modarres SZ, Kianbakht S, Huseini HF. Phytomedicine. 2014;21(6):901 to 905.

Here is the trial, as it was published:

Gloved hand holding a microscope slide in front of a screen showing few, clumped and misshapen sperm

They gave 34 men with a poor sperm test black seed oil, twice a day, for two months.

Then a lab tested them again. In the group that took the black seed oil:

Sperm count went up 39% compared with the placebo group

60% more sperm could swim after the two months

23% more sperm had the right shape on the second test

None of the men reported side effects

Measured by the same lab, before and after, against 34 men who got a placebo.

The trial followed 68 men in two groups of 34: one group took 2.5 ml of black seed oil, about 2,300 mg, in the morning and in the evening for two months, while the other group took a placebo oil. Nobody knew who had which, and that is what double blind means. All of them started in the same place, and if you are reading this, you probably know that place.

Their sperm count was too low, so month after month their wives did not get pregnant

Too many of their sperm had the wrong shape, and no doctor could tell them why

Too few of their sperm could swim, so every test came back with the same words, below normal

The waiting had followed them into the bedroom, because when every night is a test, the pressure gets into everything

And under all of it sat the quiet fear that even if it worked, weak sperm might not give them a healthy child

Healthy sperm is not only about getting pregnant

Doctors have known for years that damaged sperm is linked to more miscarriages, so the goal was never just a positive test.

The goal is a healthy baby, and a healthy baby starts with healthy sperm.

That is why the men in the trial let the lab test them twice, because they wanted to know, not hope.

Here is why black seed oil worked for these men.

The reason why these men were infertile or have bad sperm quality is because of oxidative stress.

Heat, smoke, sugar, plastic and too little sleep all leave the body with too many free radicals, and a free radical grabs a piece from the nearest cell, which in the testes is a new sperm cell.

Doctors call that oxidative stress, and 30 to 80 out of every 100 infertile men have it.

Black seed oil contains thymoquinone, an antioxidant that gives a free radical the piece it wants.

That is why the doctors in the 2014 trial picked black seed oil.

Thymoquinone · the antioxidant in black seed

1

A free radical gets to a new sperm cell and tries to grab a piece out of the soft skin that keeps the cell safe.

2

Thymoquinone gives the free radical the piece it wants, so the free radical is full and stops grabbing.

3

With fewer free radicals hitting it, the skin around the sperm cell stays whole while the new batch grows for 74 days.

4

After two months the lab checked the men on black seed oil against the men on the placebo and measured the difference in count, movement and shape.

Now the results, as the lab recorded them.

What the lab measured, before and after

This is what the trial reported after two months of taking black seed oil measured by the same lab, before and after.

AFTER

Count, movement and shape all improved in the black seed group compared with the placebo group

No side effects were reported by any of the 34 men.

That is what the 2014 trial reported, measured by the same lab, before and after.

The science is new, but the remedy is not.

Modern science is only now catching up with a 1,400 year old herbal remedy

The Prophet Muhammad from Islam, peace be upon him, said: "In the black seed there is healing for every disease, except death." (Sahih al Bukhari)

For 1,400 years, Muslim families, Unani healers and Ayurvedic doctors have used the same small seed, Nigella sativa, and quietly gave it to couples who were still waiting for a child.

They did not know the words oxidative stress, they only knew what worked.

The tradition came first, and with the 2014 trial modern science is finally catching up.

One more thing most men want to know before they start.

Is BIO black seed oil safe?

No side effects were reported in the 2014 trial

It is a superfood and not a hormone. It's been used over 1400 years in eastern medicine.

Here is how to do the same three months at home.

If you want to do the three months the way the men in the trial did, with the same oil and a certificate to prove it, there is only one place to get it.
