Causas de
Infertilidade

A infertilidade pode ser uma das experiências mais devastadoras na vida de uma pessoa. A ideia de perder a capacidade de ter um filho pode trazer desesperança e desespero às pessoas mais fortes. Felizmente, praticamente todas as formas de infertilidade podem ser superadas. Ao aprender as causas, pode-se identificar a barreira e personalizar o tratamento para conseguir uma gravidez bem-sucedida.

As causas são geralmente divididas em fatores masculinos (40%), fatores femininos (40%) e fatores inexplicáveis (20%). As barreiras que limitam a capacidade de procriar de um homem geralmente envolvem fatores que afetam sua contagem de esperma. Estes são discutidos em Infertilidade masculina.

Fatores Femininos

As principais causas que afetam uma mulher podem ser mais lembradas por sua anatomia:

  • Fatores de ovo como distúrbios da ovulação e barreiras relacionadas à idade ou ao "relógio biológico".
  • Fatores pélvicos como endometriose e aderências.
  • Fatores tubários como trompas de falópio bloqueadas ou obstruídas e trompas danificadas como hidrossalpinges.
  • Fatores uterinos como miomas, pólipos, cicatrizes ou malformações uterinas.
  • Fatores cervicais que limitam a passagem do esperma
  • Fatores vaginais como infecções bacterianas ou fúngicas recorrentes.

A causa mais comum de infertilidade em mulheres é síndrome do ovário policístico, e ainda assim é um dos mais tratáveis. Na verdade, para cada causa de infertilidade, existe um tratamento muito eficaz projetado para superá-la.

Fertilidade inexplicada

Infertilidade inexplicada é definida como a incapacidade de identificar a causa por meio de nossos testes de diagnóstico padrão, como análise de sêmen, histerossalpingograma (HSG) e teste hormonal. Ainda há uma razão, mas não tão óbvia. Um exemplo é quando todos os testes são normais, incluindo o HSG, mas os tubos não funcionam corretamente. A endometriose é uma razão subjacente comum para a disfunção tubária. A infertilidade inexplicada pode ser frustrante porque não há uma razão direta, mas existe um algoritmo adequado ou plano de tratamento que irá superar ou encontrar a razão com o tempo.

Perda de Gravidez

A perda recorrente da gravidez ou abortos espontâneos podem ser uma causa dolorosa e frustrante de infertilidade. Felizmente, existe um plano de diagnóstico e tratamento que aborda com eficácia os motivos que levam ao aborto espontâneo. É extremamente importante consultar um médico experiente e hábil no tratamento dessas perdas para ter sucesso. Alguns dos maiores avanços recentes em nosso campo lidam com a superação de causas genéticas para abortos espontâneos repetidos.

Causas da infertilidade - Idaho Center for Reproductive Medicine

At Idaho Center for Reproductive Medicine (ICRM), we recognize that infertility affects both men and women. Causes of infertility are generally categorized into female factors (40%), male factors (40%), and unexplained factors (20%).

Infertility can be one of the most devastating experiences in a person’s life, leading to feelings of hopelessness and despair. However, it’s important to know that virtually all forms of infertility can be overcome with the right approach. By understanding the underlying causes, we can pinpoint individual barriers to conception and customize effective treatment options for a successful pregnancy. Here, we provide a comprehensive overview of both female and male infertility and provide you with the next steps for overcoming an infertility diagnosis.

Female Infertility

Female infertility encompasses a range of factors that can impede a woman’s ability to conceive. Key issues include:

  • Egg Factors: Disorders of ovulation and factors related to age, often referred to as the “biological clock.”
  • Pelvic Factors: Conditions such as endometriosis and adhesions can affect reproductive organs.
  • Tubal Factors: Blockages or damage to the fallopian tubes, hindering egg transport.
  • Uterine Factors: Issues like fibroids, polyps, scarring, or structural malformations of the uterus.
  • Cervical Factors: Conditions that restrict sperm passage through the cervix.
  • Vaginal Factors: Infections, such as recurrent bacterial or yeast infections that could inhibit conception.

The most common cause of female infertility is Polycystic Ovarian Syndrome (PCOS), which is highly treatable. Whatever the cause, effective treatments are available to overcome these challenges.

Infertilidade masculina

Male infertility accounts for approximately 40% of infertility cases. It primarily revolves around the sperm’s ability to fertilize an egg. Key considerations include:

  • Sperm Production: Issues affecting the testicles’ ability to produce healthy sperm.
  • Sperm Transport Blockage: Obstructions that prevent sperm from reaching the egg.
  • Sperm Quality: Motility and morphology can significantly affect fertilization success rates.


A semen analysis is the starting point in evaluating male fertility. It assesses various sperm parameters to identify issues and guide treatment options. Treatments may include lifestyle changes, medication, or assisted reproductive technologies such as Intrauterine Insemination (IUI) and In Vitro Fertilization (IVF) combined with Intracytoplasmic Sperm Injection (ICSI).

Unexplained Infertility

Unexplained infertility refers to the inability to determine a specific cause despite standard diagnostic tests, such as semen analysis, hysterosalpingogram (HSG), and hormone testing. While no apparent reason may be found, there is often an underlying issue. One common example is tubal dysfunction resulting from endometriosis.

The frustration of unexplained infertility stems from the lack of a precise diagnosis; however, it is possible to develop a treatment plan that addresses (and possibly identifies) the underlying issue over time. Our skilled team at ICRM possesses extensive experience and success in treating unexplained infertility, providing hope and guidance on your path to parenthood.

Recurring Pregnancy Loss

Recurrent pregnancy loss or miscarriage can be a heartbreaking and frustrating cause of infertility. Fortunately, there is hope—some of the most significant advances recently in our field deal with overcoming genetic causes for repeated miscarriages. There is a specific diagnostic and treatment protocol that effectively addresses the reasons that lead to miscarriages. At ICRM, our knowledgeable physicians are highly skilled at treating recurrent pregnancy loss to find success.
