About me

I was born in Villafranca del Bierzo in 1960, I’m the second of three daughters and I grew up in La Coruña. I always wanted to be a doctor because helping others is what I like the most.

Since I was a child, music was my other passion, and the desire for self-improvement was my inspiration –the need of constantly improving everything around me.

I studied in Santiago de Compostela and then I went to Barcelona to specialize in gynaecology. I picked Assisted Reproduction because it was a very interesting new science and I fell in love with the embryos.

I have two sons at home: Borja and Bruno, one is interested in marketing and the other in medicine, the oldest son is the 4th generation of gynaecologists, carrying on the name Marquès!

I also have many children in other houses: the first thing I do every day when I arrive at the clinic is to check the pregnancy test results; positive results make me happy,  but negative ones make me angry. I won’t be happy until I see that all cycles end in success.

I divide my time between Institut Marquès’s General Management, the consultation and the Research and Development Project Team. The scientific platform ResearchGate set me among the top 10% of the most influential researchers in the world. I fell very proud!

My motivations are: our patients, their story, the colleagues at Institut Marquès, team work and everybody who is part of it. I decided to use this blog to share with all of you what happens at the clinic and also my experience as a professional in this field, which, in my opinion, it’s a privilege.

    Dear Marisa López-Teijón,

    I am writing to you to ask a question regarding success of different methods for making an infertile man fertile. I would like to no whether there is a determined percentage of success in these approaches or not. I appreciate your help if you give me statistics with its scientifin reference because I like to use them in my article.
    I look forward to hearing from you.
    Best regards,

    Would you be able to accept frozen embryos from another country where I did not have my husbands written consent as he died suddenly for transfer into me? Thanks Zareena

    • Dr. Marisa López-Teijón Reply

      Dear Zareena,
      in our country we need a consent signed by your husband to alow you to transfer this embryo. I will recomend you to ask to a specializated lawyer in your case.
      Best wishes.

    Good afternoon Dr Lopex-Teijon,

    I hope you’re having a lovely day.

    I’m a 42 year old female who has had five miscarriages ranging from week four to week 13. I have been advised by IVF specialist here in Australia that egg donor IVF is my best option.

    My partner is 45 with three children, according to his last sperm count/test he is healthy and producing good quality sperm. During my last ultra sound in September 2014 I was still producing follicles but the quality is unknow and specialist feel that the reason of miscarriage is due to the lack of egg quality.

    I’m hoping I’m a suitable candidate to have a successful pregnancy with your expertise and support.

    I have a regular 28 cycle, of a healthy weight, fit and with no known health issues. I have had IVF and IVF egg donor counselling and feel that the options you provide at your clinic best suit the needs of mine and my partner Sep.

    I’m a primary school teacher and would love to possibly commence an egg donor cycle under your care late June to early July 2016. What do you think my percentage/success rate could possible be?

    I dream about the day I get to hold my own baby and look forward to hearing back from you.

    Yours kindly,

    I am urgently seeking a pure Italian egg donor for IVF very soon; where in Italy can I look to have success?

    Thank you

    • Dr. Marisa López-Teijón Reply

      Dear Tara,

      We are a Spanish clinic and we don’t have Italian donors. I´m sorry but we can´t suggest you any other clinic.

      Kind regards

      Dear Zahid,

      We suggest to wait a year and half before to worried because your wife doesn’t get pregnant. If after one and half year you haven´t achieved a pregnancy you should try with an IVF treatment.

      Kind regards
