Imi doresc sa aud mai multe voci care sa spuna ca atunci cand pronunti ROMANIA , te gandesti la copii frumosi si sanatosi , la mame responsabile. Mergeti intr-un amfiteatru studentesc sa vedeti ce are Romania mai frumos, TINERII. Daca nu ar fi fost oprite repartitiile guvernamentale in 1982, 1983 , azi am avea printre studentii de la medicina si copii din orfelinate si nu am vorbi de parinti decazuti din drepturi parintesti. Au fost familii la tara care au avut si cate patru copii studenti in faculatatile de stat.Ce s-a intamplat cu ei? Ce mult conteaza linistea sufleteasca pentru a aduce pe lume si a creste copii normali!
Sa luam din America tot ce are mai frumos si sa vorbim lumii despre valoarea FAMILIEI ROMANESTI si A SCOLII ROMANESTI, nu despre razboiul impotriva terorismului, scut anti-racheta.
A. « DEFINITION of Fertilization, IN VITRO.
Fertilization, in vitro : IVF, a laboratory procedure in which sperm are placed with an unfertilized egg in a Petri dish to achieve fertilization. The embryo is then transferred into uterus to begin a pregnancy or cryopreserved (frozen) for future use.IVF was originally devised to permit women with damaged or absent Fallopian tubes to have a baby. Normally a mature egg is released from the ovary (ovulated), then enters the Fallopian tube, and waits in the neck of the tube for a sperm to fertilize it. With defective Fallopian tube , this is not possible . The first IVF baby, Louise Joy Brown was born in England in 1978. In vitro fertilization, literally means « fertilization in glass ». A child born in vitro fertilization is inaccurately known a « test tube baby ».
IN VITRO : Literally in glass, as in a test tube. A test that is performed in vitro is one that is done in glass or plastic vessels in the laboratory.
In VITRO is the opposite of in VIVO (in a living organism). »] SOURCE : MedicineNet.
B.[« Merck Receives European Approval For ELONVA (R) (corifollitropin Alfa Injection), a New Fertility Treatment.

Article date : 30 Jan 2010 -1 :00 PST.
Merck &Co., Inc., which operates outside the U.S. and canada as MSD, announced the European Commission (EC) approval of ELONVA (R) (corifollitropin alfa injection). ELONVA is indicated for controlled ovarian stimulation (COS) in combination with a GnRH (gonadotropin –releasing hormone)antagonist for the development of * follicles in women participating in an assisted reproductive technology (ART) program. With the EC approval, Merck receives marketing authorization for ELONVA with unified labeling valid in all EuropeanUnion Member States. Schering –Plough Corp. And Merck &Co., Inc., merged on Nov.3, 2009. ELONVA is the first sustained follicle stimulant. Due to its ability to initiate and sustain * follicular growth for an entire week, a single subcutaneous injection of the recommended dose of ELONVA may replace the first seven injections of any conventional daily recombinant follicle stimulating hormone (rFSH) preparation in a COS treatment cycle.
« The European approval of ELONVA is a positive step towards reducing the burden of injections for women experiencing difficulty conceiving », said Mirjam Mol-Arts, senior vice president , Merck Research Laboratories. « merck is proud of the company’s women’health portofolio and is committed to provinding effective patient –focused fertility treatments. »] SOURCE : Medical News TODAY.
Si un punct de vedere romanesc deloc de neglijat:
« STERILITATEA FEMININA. Nu putem intra in clinica sterilitatii feminine fara a preciza ca in literatura se vorbeste mai mult de o « sterilitate conjugala ». Experienta noastra ne arata ca factorul masculin este intalnit ca factor etiologic in aproximativ 40% din cazuri (direct sau indirect prin imbolnavirea femeii).ETIOPATOGENIA. Dupa cum am mai amintit , factorii etiologici ai sterilitatii conjugale intereseaza atat componenta masculina cat si cea feminina. Drept conduita generala, investigatia sterilitatii conjugale trebuie sa inceapa cu investigatia barbatului, care este cu mult mai simpla decat investigatia femeii.A.Cauze * : ocupa aproximativ 40% din cauzele sterilitatii conjugale. Dintre cele mai frecvente enumeram : a) tulburari in spermatogeneza :azoospermia, astenospermia, oligospermia si necrospermia.Aceste tulburari in spermatogeneza sint datorite fie unei alimentatii deficitare (lipsa de proteine, vitamine A,B, E), intoxicatii cu tutun, alcool, morfina, intoxicatii profesionale, tulburari organice ale barbatului (debilitate fizica constitutionala, boli infectioase, anemie, epuizare, emotii, psihopatii). Tulburarile genitale * ca : orhite specifice si nespecifice, tumori testiculare etc. sint de asemenea incriminate. Tulburarile hormonale : hipopituitarism, hipogonadism, diferite traumatisme care duc la alterarea cailor seminale, interventiile chirurgicale, tulburarile de potenta, ejacualre precoce etc., sint tot atatea cauze care pot fi incriminate ca provocatoare de sterilitate.b) Malformatiile penisului : hipospadias, cu deschidere la radacina penisului, extrofia canalului uretral. C) Coitul contra naturii (* etc.)B.Cauze feminine : constituie aproximativ 40% din cauzele sterilitatii conjugale.C. Cauze generale : predispozitia constitutionala joaca un rol favorizant.Astfel, femeile de tip intersexual prezinta mai rar sarcini. D.Cauze sexuale : hipoestezia sexuala, dispareunia, vaginismul, perversiunile sexuale , pot sa fie cauze indirecte de sterilitate. Au mai fost incriminate, drept cauza de sterilitate, incompatibilitatile sau ostilitatea ovocitelor fata de anumiti spermatozoizi. E.Cauze de natura psihologica : desi mai putin studiati, factorii psihologici pot influenta negativ fertilitatea femeii.Astfel, femeile cu un psihic labil, ce trec usor de la stari de depresiune , la stari euforice, pot prezenta lipsa ovulatiei. » I.Negrut, O.Rusu – « Ginecologie si obstetrica » vol.1, Ed.Didactica si Pedagogica Bucuresti 1981, p.246.
