Neonatal throat swabs testing of eight newborns for SARS-CoV-2 was negative, as well as breast-milk samples from three parturients (2) . Nevertheless, living with uncertainty, has led most countries to outright cancel all assisted reproductive technology (ART)/ IVF interventions and actually all fertility treatments, except of fertility preservation in patients exposed to gonadotoxic chemo-or radiotherapy. However, due to the declining success rates of ART/IVF in late reproductive age women, several countries have reintroduced and many more are considering resuming these treatments, initially in women older that 39 years, and later even to younger patients. It is imperative, therefore, to know whether SARS-CoV-2 may infect gametes and embrya, considering the possible consequences of COVID-19 pandemic on natural conceptions and on ART/IVF generated pregnancies. Most recently, in a report from a Wuhan university hospital in China, none of the serum or throat swab of the newborns of six parturients with confirmed COVID-19 displayed SARS-CoV-19 using RT-PCR (1). However, their neonatal umbilical blood did display virus-specific antibodies Most recently, a Massachusetts-based pharmaceutical laboratory has developed a coronavirus vaccine called mRNA-1273, which has been tested on human volunteers, apparently effective. It is hoped that these preliminary encouraging reports are validated and prove reliable. It is, therefore, suggested to consider immunizing first infertile couples, before ART/IVF with these vaccines, after proven safety and efficacy, before turning on to global immunization of all the public. The COVID19 disease challenges all the medical specialties, including reproductive medicine. Since many clinical questions remain unanswered yet, all the health care providers need to be on the alert, amend and adjust the treatment modalities according to the day-to-day changing information and published experience on the behavior of this new and unknown disease.
