Křečík Roborowského se v posledních letech stal jak miláčkem mnoha domácností, tak i častým chovancem v teráriích polopouštních biotopů, a o jeho zdárný odchov se snaží řada chovatelů hlodavců. Není to způsobeno pouze milým, neagresivním chováním – byť velmi plachým, ale také vyšší cennou, za kterou jsou vykupováni a dále distribuováni. Poptávka je vyšší než nabídka – o tom není pochyb, ale relativně vysoké nároky těchto drobných hlodavců jsou častou příčinou neúspěchu velkochovů, a tak většina odchovů pochází od drobných chovatelů.
I přes skutečnost, že křečík Roborowského k nám byl poprvé importován počátkem 70. let, nikdy nedošlo k tak masivnímu rozšíření jako v případě křečíka džungarského ( Phodopus sungorus), jehož cena v období odchovu mláďat klesá na cenu krmných hlodavců ( tzn. téměř v průběhu celého roku). Oproti tomu je křečík Roborowského velmi sezóní druh, a pohlavně dospívá také relatinvě dlouho ( asi tak po půl roce).
I přes svou již zmíněnou plachost, láká svým okouzlujícím vzhledem. Má popelavě šedou podsadu a okrově růžové, dlouhé pesíky. Břicho i celá spodní část těla je bílá. Vousky směřují hodně kupředu a dávají tak charakteristický tvar čumáčku. Zvláštností jsou ochlupená chodidla. Barevné mutace nejsou známy.
V přírodě žije v oblastech Mongolska, severní Číny apod. Obývá hlavně pouště a polopouště. Aktivní je po celý rok. S kontinentálním podnebím a s tímto spojeným teplotním rozdílem během dne a noci se zvířata vyrovnávají spánkem. Za potravou se vypravuje v podvečer a brzy ráno. Hrabají si asi 1 m hluboké nory, a často sídlí i v převisech pohyblivých dun.
Křečík Roborowského není příliš snášenlivý, ale vůči jedincům stejného druhu není nikdy tak agresinví jako jeho příbuzný – křečík džungarský. V zajetí je lépe chovat jej v párech, nebo v menších skupinách ( 1;2). Co se prostoru týče, pro pár postačí terárium 25x25 cm a více. Jako podestýlku můžeme použít jak písek, tak i obyčejné, ne příliš prašné hobliny. Podobně jako v přírodě mají tendenci vystýlat si pelech srstí, která často ulpívá i na skle. Přestože v přírodě obratně loví drobný hmyz, v zajetí se často leká a dává tedy přednost kočičím granulím, kousku vajíčka apod. Jinak krmíme směsí drobnějších zrnin a olejnatých semen, přidáváme čočku, rýži … Kousky ovoce a zeleniny, v létě listy smetanky a vojtěšky. Lepší je napájet.
Sexuální dimorfismus není u mladých zvířat nijak patrný. V pohlavní dospělosti zkušenému chovateli neunikne drobnost samic oproti samcům. Rozlišování pohlaví u mladých jedinců je také věc velice nesnadná.
Podle literatury může mít samice mláďata až v 10-ti vrzích za sebou, ale v mém chovu nebylo výjimkou i 15 nebo 20 vrhů ( mortalita mláďat se však – k nelibosti chovatele – se stářím samic neúměrně zvyšuje a poslední z těchto vrhů bývá zpravidla bez odchovaných mláďat). Březost trvá asi kolem 20 dní, počty mláďat jsou od 3 do 5 ( rekordní počet v jednom vrhu byl 9 mláďat). Rodí se přirozeně holá a slepá, samostatného života jsou však schopna už od 3 týdnů. Dožívají se relativně vysokého věku na tak drobného hlodavce – často i 3 let.
Rozhodnete-li se právě pro křečíky Roborowského, přeji vám hodně štěstí v chovu i odchovu, i spoustu zábavy při pozorování života jednoho z nejmenších hlodavců na světě.

IVF in Dubai
(IVFfes, 5. 9. 2019 12:45)
More information: https://bitly.com/newhopeivf
What is IVF?
IVF is a reproductive technology which involves the process of fertilization by retrieving a sperm sample extracting eggs and manually combining the two in the laboratory dish. IVF is usually artificially inseminated and is used to treat infertility in patients with conditions such as damaged or blocked fallopian tubes, male factor infertility, removed fallopian tubes, genetic disorder, ovulation disorder as well as unexplained infertility to mention a few.
IVF treatment involves four steps which are; Ovulation induction, Egg retrieval, fertilization and Embryo transfer and implantation. In few weeks after the insemination, you can take a pregnancy test to confirm the success of the result. Although the average couple may have to undergo the process twice or thrice but once the process succeeds, there is no difference between it and a naturally conceived pregnancy.
Is it Safe To Do IVF Treatment?
However, a lot of people have questioned the safety of the IVF fertility treatment, couples with fertility issues are usually concerned about IVF dangers and risks especially to the mother and the baby. While some risks are minimal, some are increased, in fact there are inherent risks that makes people who are in need of this fertility treatment have a higher risk pregnancy. However, the most widely feared risk of IVF is multiple pregnancies which is a condition where a woman has two or more babies in her uterus, the babies could come from different eggs or the same egg. Fertility doctors usually give advice about the number of embryos to transfer but because of the high cost of IVF people usually believe that multiple embryo transfer increases the chance of getting pregnant, this is thus the result to the high tendency for twins’ birth in IVF treatment.
Women who are pregnant with twins are at a higher risk for pregnancy complications which include premature birth, cesarean section, TTTS (Twin- Twin Transfusion Syndrome), low birth weight and gestational diabetes amongst others. Women are also at risk over reaction to hormone drugs that are used to stimulate the ovaries besides, egg collection may be uncomfortable most likely because it is sometimes performed with, local anesthetics. There is also the risk of bleeding during egg retrieval and damage or infection of the bladder or bowel. Couples also usually fear the risk of ectopic pregnancy which is has a low percentage in IVF treatment. The whole process of artificial insemination can also lead to psychological stress and emotional problems. Generally when the consultants are experts and patients follow the advice of their consultants, IVF is usually safe.
IVF success rate usually declines once patients reach the age of 35 but before that patients usually have a fifty percent chance.
In Dubai, IVF treatment is one of the most sought after service because of many couples’ desire for pregnancy. Around the world, three percent of babies are born through IVF, in Dubai, the reason for infertility rate boils down majorly to stress, late marriage and genetic disorder which is why they have to visit infertility clinics in Dubai. Most successful fertility treatments usually depend on expertise of the consultant.
How Much Does IVF Cost in Dubai?
For couples in Dubai who are open to the option of artificial insemination, the price is usually the deciding factor that dictates what pregnancy treatment and fertility clinic to consult. In Dubai, the cost of IVF in fertility clinics is usually between the range of AED 25,000 – 40,000 including consultation fee.

A short while ago I've come across one article which I assume you can find helpful. Someone will take a steaming dump all over it, but it clarified some of my questions.

Best IVF Center in Dubai
(BestIVF, 20. 8. 2019 21:09)
The first successful birth of a child after IVF treatment, Louise Brown, occurred in 1978. Louise Brown was born as a result of natural cycle IVF where no stimulation was made. The procedure took place at Dr Kershaw's Cottage Hospital (now Dr Kershaw's Hospice) in Royton, Oldham, England. Robert G. Edwards was awarded the Nobel Prize in Physiology or Medicine in 2010, the physiologist who co-developed the treatment together with Patrick Steptoe and embryologist Jean Purdy; Steptoe and Purdy were not eligible for consideration as the Nobel Prize is not awarded posthumously.
The second successful birth of a test tube baby occurred in India just 67 days after Louise Brown was born. The girl, named Durga conceived in vitro using a method developed independently by Dr. Subhash Mukhopadhyay, a physician and researcher from Kolkata, India.
With egg donation and IVF, women who are past their reproductive years, have infertile male partners, have idiopathic female-fertility issues, or have reached menopause can still become pregnant. Adriana Iliescu held the record as the oldest woman to give birth using IVF and a donor egg, when she gave birth in 2004 at the age of 66, a record passed in 2006. After the IVF treatment some couples are able to get pregnant without any fertility treatments. In 2018 it was estimated that eight million children had been born worldwide using IVF and other assisted reproduction techniques.
Leftover embryos or eggs
There may be leftover embryos or eggs from IVF procedures if the woman for whom they were originally created has successfully carried one or more pregnancies to term. With the woman's or couple's permission, these may be donated to help other women or couples as a means of third party reproduction.
In embryo donation, these extra embryos are given to other couples or women for transfer with the goal of producing a successful pregnancy. The resulting child is considered the child of the woman who carries it and gives birth, and not the child of the donor, the same as occurs with egg donation or sperm donation.
Typically, genetic parents donate the eggs to a fertility clinic or where they are preserved by oocyte cryopreservation or embryo cryopreservation until a carrier is found for them. Typically the process of matching the embryo(s) with the prospective parents is conducted by the agency itself, at which time the clinic transfers ownership of the embryos to the prospective parents.<>6]
In the United States, women seeking to be an embryo recipient undergo infectious disease screening required by the U.S. Food and Drug Administration (FDA), and reproductive tests to determine the best placement location and cycle timing before the actual Embryo Transfer occurs. The amount of screening the embryo has already undergone is largely dependent on the genetic parents' own IVF clinic and process. The embryo recipient may elect to have her own embryologist conduct further testing.
Alternatives to donating unused embryos are destroying them (or having them implanted at a time where pregnancy is very unlikely), keeping them frozen indefinitely, or donating them for use in research (which results in their unviability). Individual moral views on disposing leftover embryos may depend on personal views on the beginning of human personhood and definition and/or value of potential future persons and on the value that is given to fundamental research questions. Some people believe donation of leftover embryos for research is a good alternative to discarding the embryos when patients receive proper, honest and clear information about the research project, the procedures and the scientific values.
