Wow, how time flies. Seems like summer just started yesterday and it’s already over. I’m sure like most of you, our kids always seem to find too many activities to get involved with and we (well mostly my wife) spend all our “spare” time running them to all their events. Oh, the joys of parenthood. Even though we complain, we wouldn’t have it any other way.  Kind of like the ET business.  We spend all those late nights flushing cows and transferring embryos, but we wouldn’t have it any other way.

I’m very excited about the program that has been put together for the upcoming meeting in Madison. Looks like our program committee has something for new practioners, more experienced practioners, technicians, and students alike. The program is very deep in content and it looks like there will be very useful information gleaned from every part. I’m also very excited that we are working harder than ever to attract students to our meetings. With this year’s meeting proximity, we are hoping to have a great student turnout and the program has certainly been altered to reflect this. I also want to send out congratulations to the 6 scholarship winners this year. I understand there were many great applicants and those that were selected are truly outstanding. I would like to extend a thank you to all our great sponsors and vendors. Without their support, this meeting would not be the great event that it has become. Our pre-conference social looks to be a stellar event and we have some very special presentations planned for the banquet, so please plan to attend these important affairs.

I am very proud to be the leader of this organization for 2014. The AETA is a great organization because of the great men and women that have, do, and will make up its leadership and membership. Thank you to everyone that has put together a tremendous effort so far and I look forward to seeing you all in Madison.

  5. Learn about fascinating topics like embryo transfer history, reproductive physiology and synchronization, superovulation, ultrasound biomicroscopy, fetal programming effects on reproduction, embryo biopsy and treatments to improve preg rate, follicular reserve, yearling heifer reproduction, and age effects on oocyte development and competence
  6. Technician and student breakout sessions on Embryo Handling, Lab Sterility, Safety and Quality Control, Embryo Cryopreservation, and Export Documentation
  7. Student-mentor luncheon and other opportunities to interact with students wanting to enter the embryo transfer industry

Evidence-based ET: What is the best synchrony between IVP embryos and recipients?

Evidence-based ET

John F. Hasler

Note: I have been using subjects suggested by our board of directors for this column for the past two years.  I would be happy to attempt covering any subjects that the membership might suggest. Let me hear from you!

What is the best synchrony between IVP embryos and recipients?

There is a great deal of evidence that synchrony between the age of in vivo-derived embryos and the day of the estrous cycle in recipients at the time of transfer is affected very little, if at all, when synchrony is within the three day period of 0, plus one or minus one day (zero, meaning day of estrus and age of embryo are the same).  Consequently, the pregnancy rate is not affected when day 7 embryos are transferred into day 6, 7, or 8 recipients.  This holds true for both fresh and frozen in vivo-derived embryos (Hasler, 2001).

In Memoriam: Edwin Robertson

The AETA has lost a very special member.  Dr. Edwin Robertson died suddenly at his home on July 29th.

Certainly most members will remember Edwin’s consistent presence at the annual meeting.  And many will recall that he served on the Board of Directors and that he was the President of the AETA in 1989-1990.

Perhaps not as many members are familiar with Edwin’s life beyond the AETA.  This was a life that was literally packed with service.  It is staggering to consider how several individuals might have accomplished all that Edwin accomplished, let alone the fact that his was the life of one man.

Edwin was a committed Christian; his life of service flowed naturally out of his commitment to that faith.  He was a member and served on the staff of Pump Springs Baptist Church.  There he taught the Real Life Sunday School class.  And he helped organize several ministries including Celebrate Recovery, the Claiborne Refuge House, and the Jail ministry.  He was the former Director of Cumberland Gap Youth Fellowship and the Tri-State Area Crusade for Christ Director.
