Cryopreservation in IVF

Cryopreservation is a new trend in Assisted Reproductive Techniques which has a great role in the management of different issues especially fertility preservation.

Types of Cryopreservation:

  • Semen Cryopreservation sperm banking

It is a procedure to preserve sperm cells It can be used to preserve fertility for men undergoing vasectomy or treatments that may compromise their fertility, such as chemotherapy, radiation therapy and surgery.

  • Human oocyte Cryopreservation ( egg freezing) 

The eggs are extracted, frozen and stored to help the woman have the eggs thawed, fertilized and transferred to the uterus as embryos in the future.

 

  • The procedure success rate varies according to the age of the patient( being higher in younger ages) the fluid content of the oocyte, the mitotic spindle and zone hardening.
  • This procedure is helpful in cancer patients who have not begun chemotherapy or radiotherapy.
  • Patients who like to preserve fertility in the future either due to absence of partner or other medical and personal causes.
 
   

 

 

 

 

 

 

 

 

 

 

 

  • Embryo Cryopreservation:

             Preservation of the embryo during an embryogenesis stage from fertilization to  

            the blastocyst stage.  

 

  • It is useful for leftover embryos after a previous cycle of IVF or ICSI to help patient to avoid a full IVF cycle.

 

  • Techniques used for embryo Cryopreservation:

        The main techniques are vitrification versus slow programmable freezing

  • Vitrification in IVF can allow freezing of spare embryos with better post_ thaw survival rates and higher pregnancy and live birth rates from frozen embryo transfer cycles due to lesser incidence of DNA breaks.

 

  • Bedaya hospital has more than twenty tanks for Cryopreservation serving thousands of cases using the vetrification technique for all cases of embryo and oocyte Cryopreservation
  • This service is available with the lowest cost for more than twenty years with best quality.

 

 
   

 

 

 

 

                                                                                           

Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source.

Lorem Ipsum comes from sections 1.10.32 and 1.10.33 of “de Finibus Bonorum et Malorum” (The Extremes of Good and Evil) by Cicero, written in 45 BC. This book is a treatise on the theory of ethics, very popular during the Renaissance. The first line of Lorem Ipsum, “Lorem ipsum dolor”, comes from a line in section 1.10.32.

There are many variations of passages of Lorem Ipsum available, but the majority have suffered alteration in some form, by injected humour, or randomised words which don’t look even slightly believable. If you are going to use a passage of Lorem Ipsum, you need to be sure there isn’t anything embarrassing hidden in the middle of text. All the Lorem Ipsum generators on the Internet tend to repeat predefined chunks as necessary, making this the first true generator on the Internet. It uses a dictionary of over 200 Latin words, combined with a handful of sentence structures, to generate Lorem Ipsum which looks reasonable.
