100% Swedish made Sperms to celebrate life!

The first glass sperms

My first sperm designed for glass was made at the Skansen -open-air - museum in Stockholm 1986 as a gift to Lars Björndahl defending his thesis. In 2015, I went in to Kastlösa Glashytta ( glassworks) on the Swedish island Öland in the Baltic Sea. I met the glass-artist Poul Jörgensen who at 12 years of age started his career as glassblower at the Danske Porslinsfabrik in Copenhagen, Denmark followed by Kosta Orrefors in Sweden.

I asked Poul “Can we do glass sperm ?” and he said yes. Four hours later we had 8 huge, 60 cm long Crystal Sperm with Blue Nucleus
(magnification x 10 000!).

The Crystal sperm, with blue nucleus was namned the ANOVA CLASSIC CRYSTAL SPERM. That was the beginning of something big for us. 


The ANOVA Crystall Sperm family grew and besides the Classic coloured with cobolt came the blue-green Nordic Ice, The Deep Purple,

The Purple The golden and the silver ones with the nucleus rolled in blade silver and gold.

The ANOVA Golden Red is a special one. Poul had 50 kg of crystal glass with genuine gold as a legacy from the Kosta Orrefors.

The very first Golden Red was made to honor Swedish women January 2016 when the ACT was taken that gave Swedish single women the right to be inseminated.

The ANOVA Golden Red was given to the Swedish organization RFSU  at the celebration party.

The collection grew overtime and I started to experiment with different combination of sperms and eggs. 

Exhibitions and stories

I spend a lot of time lecturing about sperms, eggs and life and I think that it is very important to spread knowledge. Therefore I have started with exhibitions where I tell stories about my work as a fertility scientist. I recently had a month-long exhibition in Trosa, Sweden about the work I do here at ZincZperm and the message I try to convey. I try my best to tell about the greatness and mystery of life, God's part in it, and my perspective on it. The glass sperms and eggs that I and Paul create together is my way of expressing the beauty of life and that we should honor it more often. Please contact me if you have a similar project that I could contribute to.

Making a Sperm and an Egg

Me and Paul 2016 Me and Paul 2016

The process of making a sperm is complicated and requires both the right tools and the technical knowledge. I have been fortunate to have worked with the talented Paul Jørgensen for the last few years and he has helped me making this vision come true. I wanted to include some behind the scene videos and description of how they are made which can be found further down this page.

The spermatozoon of glass is developed in distinct steps, like the spermatozoon in the testis: First the nucleus with chromatin DNA is formed, and then the head, followed by the tail outgrowth.

The nucleus: A clump of semi-liquid glass is attached to the top of a glassblower rod. The clump is rolled in cobalt salt which colours the hot glass purple which after cooling turns blue. The hot nucleus is shaped by rolling it in a glove.

The head: The nucleus is then dipped into molten glass to add more glass that covers and extends beyond the nucleus. The head is shaped by rolling it in wet old newspapers as shown in this 
video.

The Tail: A second rod is dipped into liquid glass and a ball of new glass is mounted on the head. With help of rotation, gravity and metal pliers the curved tail is formed.
The loop. 

Finally, the tip of the head is heated with a flame of acetylene and a small lump of glass is attached to the head. With a metal pliers,the glass mass is drawn out and bent back to form a loop for the attachment. 

The spermatozoon is thereafter left for 24 hours in room temperature to cool down. 

My background in biology

I started to study medicine at the Karolinska Institutet 1968. In 1970 I became tutor for younger students at the Department of Physiology and went into sperm and fertility research at the Rune Eliasson Laboratory. Rune Eliasson was then one of the authors of the WHO manual On semen analysis to come. The legacy to study and teach sperm physiology is now forwarded and 52 years later, 2020, a research student of mine, Lars Björndahl is the chief-editor for the new WHO-manual On semen Examination, to come. In April 2020 a common doctorand to Lars and and me, Emma Holmes defended her thesis on a ZOOM- event: On Osmolality and Sperm Function During Processing for assisted Reproduction where Emma summarizes knowledge from 1856 into a new paradigm for treatment of infertility for the 2020-ies.

My research focus is still on the sperm nucleus that carries the genetic legacy from the grand-parents to future generations to be. In the 1980's I shared this interest with the Swedish photographer Lennart Nilsson whom I had the opportunity to work with preparing spermatozoa during some 15 years for his books, films and some pictures. Another common doctorand Petr Houska will further explore and reveal these mysteries in the sperm nucleus in his thesis to come.

Anova

ANOVA is a world famous Research unit at the Karolinska Institutet and a Clinic at the Karolinska University Hospital, Stockhlm, Sweden and deals with Andrology, Sexual medicine and Transgender medicine.

I worked as lecturer in andrology , and associated professor in physiology and as Head of Andrology Laboratory, ANOVA , Karolinska University Hospital & Karolinska Institutet 1992-2012.
At the Karolinska I had the opportunity to lecture and introduce doctors to be into the field of male reproduction and sexual medicine for 50 years.

Nowadays, I feel obliged to tell in public and in churches about the commonly unknown processes that results in creation of healthy and fertile human beings. How “Gods creation” is effectuated when it comes to biology. The creation of a fertile woman being the default way and the creation of a fertile man preferring women being an individual experiment of nature for every man born.

I reason, with the insight that you are the one you became, tolerance and acceptance in society and churches will grow.
