Fertilization can be carried out using "standard ЭКО " or ICSI (in particular, ПИКСИ , IMSI and PIMSI). In standard IVF, eggs are placed in a special medium in a suspension of sperm cells and left in an incubator for several hours. In ICSI, the embryologist selects the sperm himself (assessing its motility and morphology) and inserts it into the egg. Since the egg is very small (about 1/10 mm) and extremely sensitive to external influences, the ICSI procedure requires very high qualifications. PIXIES, IMSI, and PIMSI differ from the "simple" ICSI in a more complex way of selecting sperm.
Next, the embryologist cultivates the embryos in special media, in special cultivation cups, in incubators with constantly controlled temperature, humidity and concentration of gases in the atmosphere. Cultivation takes place within 5-7 days with regular assessment of embryo development and periodic change of media and plates. At the end of cultivation, the embryologist, together with a reproductive specialist, transfers the embryos into the uterine cavity. If necessary, the embryologist performs an auxiliary hatching procedure before the transfer.Also, if necessary, the embryologist freezes embryos, eggs and spermatozoa.
A separate procedure can be performed PGD – preimplantation genetic diagnosis (checking the embryos for genetic abnormalities). To do this, the embryologist performs a biopsy of the embryos — removal of one to several cells from the embryo. This is — the most delicate embryological operation that not all embryologists can perform. The biopsy material is sent to a genetic laboratory for genetic analysis.
Thus, the embryologist:
- evaluates the quality of the obtained biomaterial: spermatozoa and eggs;
- performs fertilization in the laboratory;
- creates and controls optimal cultivation conditions;
- monitors that how embryos develop;
- performs assisted hatching;
- performs embryo biopsy;
- cryopreserves embryos, oocytes, and spermatozoa.

Questions and answers
Is there a better sleep aide i can get other than what I have been using over the counter
Is there a better sleep aide i can get other than what I have been using over the counter. I know getting Ambian is a big hassle but is here something in between? I've been using Ambian for about 10 years almost daily, if it matters.
Ambian is a one the brand names of Zolpidem. It's available in Russia. You can schedule appointment with neurologist (Dr. Maslak, for example) and doctor will do prescription for you ( for Zolpidem or maybe another sleeping pill).
Rhinoplasty after 40
I would like to do a rhinoplasty, but it is said in some sources that “rhino” is not indicated after 40.
Good afternoon, Lydia. Rhinoplasty is allowable in your age. Dr. Levine, for example, performs rejuvenation in conjunction with rhinoplasty. The human nose grows throughout life. It becomes longer and more unattractive in adulthood. The rhinoplasty in conjunction with a facelift helps to achieve more pronounced
results of rejuvenation.

What to do first
What should I do first: Laser Fraxel and then the fillers, or Vice versa?
Good afternoon, Larisa. It is usually recommended to start with laser rejuvenation techniques, and then "polish" the result with hyaluronic acid injections. We invite you for a consultation. You can make an appointment by tel.: + 7 (495) 933 -66-54

Malignant kidney tumor
CT scan revealed a malignant kidney tumor in my brother. The tumor size is 3x7, which corresponds to stage 2. Tell me, please, how long does it take for such a tumor to be developed? And is it possible to remove the tumor surgically (total kidney removal)?
For a more precise answer we need to assess patient’s CT scans ourselves. At the EMC’s Urology clinic, both total and partial kidney removal with tumor is performed using the da Vinci robot. These surgeries are very gentle with fast postoperative recovery.
Prostate cancer
I am 74 years old. Prostate cancer was diagnosed. Total PSA was 25.8 ng/ml. Outpatient check-up was carried out. Are "Zoladex" injections enough? Biopsy revealed moderately poorly-differentiated small-acinar prostate adenocarcinoma. Where to start?
You should start with an extended examination, namely: skeleton scintigraphy, pelvic MRI, oncological examination. If the results of these tests will be the normal: surgery or radiotherapy may be offered (both with/without “Zoladex” therapy). If the results are abnormal: radiation therapy with/without “Zoladex”
therapy or “Zoladex” therapy may be offered.
