For the first time , scientist have filmed the unconscious process by which eggs are free from ovaries duringovulation — and they ’ve becharm it in keen detail .
In the impressive fresh video recording , a mature computer mouse bollock cadre is explosively discharge from its fluid - filled sac — known as a follicle — into a lab peach . The team observed follicles that had been isolate from mice and then grown in petri bag before being encouraged to ovulate with the help of specific hormones .
Watch as an egg is released from a follicle in real-time.
Researchers captured this minute using a new imagination proficiency that can be used in animation tissues , which they key out in a study published Oct. 16 in the journalNature Cell Biology .
Ovulation unfolds similarly in human beings as it does in mouse . Women of reproductive geezerhood typically release one mature egg from theirovariesinto the fallopian tubesat around twenty-four hour period 14 of their 28 - day menstrual cps . Then , follow ovulation , the testicle travels through the fallopian tube to the womb . If the egg isfertilized by a sperm cellas it makes its way to the womb , it can potentially shape an conceptus ; if not , period presently begins and expels the egg from the body .

A mature egg after it has been expelled from a follicle during ovulation, pictured in high resolution under a microscope. The egg can be seen as a small purple circle in the upper-middle portion of the image.
Historically , scientist have struggled to study the mechanism that control ovulation in living organism because the process occurs late inside the body , the authors of the unexampled theme take note . accordingly , most of what we currently know about ovulation has hail from looking at tissue that have been extract from the ovaries and then fixed in a solution so they can be viewed under a microscope outside the body . At that point , the preserved tissue are not alert .
In the unexampled cogitation , the researchers used the raw imaging technique to view the full process of ovulation unfold in living mice follicles in lab dishes .
They show that ovulation take place in three discrete phases . First , the tumid and most matured follicle in the ovary expands in size — growing about 1.5 - fold — over the course of eight hours . This physical process is driven by the secernment of a pith calledhyaluronic acid , which indirectly make fluid to flow into the follicle . Then , heftiness cells in the outermost layer of the follicle chop-chop sign , before finally squeezing out the bollock within .
In separate experiments in the same study , the researchers found that stymie any of these three steps from happening block ovulation , intend the egg was n’t put out . This demonstrates how vital each of the step are .
" Our determination show that ovulation is a remarkably rich process , " work co - authorMelina Schuh , director of the Max Planck Institute for Multidisciplinary Sciences in Germany , said in astatement . " Although an international stimulus is essential to trigger ovulation , the subsequent processes operate independently of the respite of the ovary , as all the necessary information is hold within the follicle itself , " she sound out .

Schuh and fellow worker now hope their imaging proficiency will be used to further enhance our reason of ovulation and distaff fertility .
" With our new method , we and other researchers can further investigate the mechanisms of ovulation and hopefully gather new insights for human fertility research , " she say .
