An understanding of the structure of the virus has It is an enveloped posive-sense single stranded RNA helped in developing prevenve and treatment virus with four main structural proteins i.e. Spike (S) strategies against it. protein, Membrane (M) protein, Nucleocapsid (N) protein and envelope (E) protein(2). In SARS-CoV-2, the spike protein, which has been imaged at the atomic level using cryogenic electron microscopy, is the protein responsible for allowing the virus to aach to and fuse with the membrane of a host cell; specifically, its S1 subunit catalyzes aachment, the S2 subunit fusion. It binds to angiotensin receptor conversion enzyme 2 (ACE2) on host cells for viral entry and with the help of Transmembrane serine proteases 2 (TMPRSS2) is incorporated in host cell wall(3).Inial spike protein priming by transmembrane protease, serine 2 (TMPRSS2) is essenal for entry of SARS CoV 2.] The host protein neuropilin 1 (NRP1) may aid the virus in host cell The Need of Vaccination Impact on Reproduction: Covid 19 may influence both male and female steroidogenesis, germ cells and reproducve health.(4) The reproducve system in both sexes has abundant ACE2 receptors and are suscepble to SARS CoV 2 infecon. Studies have suggested that downregulaon of ACE 2 may cause alteraon in follicular development and oocyte maturaon affecng their quality and subsequently affecng embryo development. Also increased oxidave stress may have detrimental pro inflammatory effect. Endometrial recepvity may also be altered leading to unfavourable outcomes.(5) Hajizadeh Malekiand Tarbian conducted a prospecve, longitudinal cohort study of 84men with confirmed COVID 19, and 105 men without the disease in Iran. The researchers analyzed changes in angiotensin-converng enzyme 2 (ACE2) acvity, markers of inflammaon and oxidave stress, apoptoc variables and semen quality, all of which were evaluated at 10-day intervals for up to 60 days. They also had higher levels of reacve oxygen species and lower superoxide dismutase acvity compared with healthy controls. The markers of inflammaon and oxidave stress in sperm cells of men with COVID-19 were increased by more than 100% compared with controls, according to the researchers. Sperm concentraon was reduced by 516%, mobility by 209% and sperm cell shape was altered by 400%.Although these effects were reported to improve over me — represenng “a transient state of male subferlity like those with oligoasthenoteratozoospermia” — the researchers wrote they remained “significantly and abnormally higher in the COVID-19 paents, and the magnitude of these changes were also related to disease severity.” Basigin (BSG) is also one of the most crucial receptors for COVID-19 that mediates its entry to host cells. BSG is expressed not only in the uterus but also in the stroma and granulosa cells of the ovary. BSG may play a role during follicle development, corpus luteum formaon and embryo implantaon. In men viral orchis may develop and impair semen parameters albeit transiently. The long term effects sll need to be evaluated.(6) Covid 19 infecon in pregnant women is more severe than their nonpregnant counterparts with increased morbidity and mortality and adverse perinatal outcome in the form of preterm birth, growth restricon, sll birth and increased caesarean delivery(7)(8). Also vercal transmission though not proven is sll a possibility.(9) The psychological effects of stress due to fear of the disease, social restricons and financial implicaons may also disturb the HPO axis. Drugs used in the treatment of Covid 19 infecon and sanizaon agents in the environment may also result in changes at the molecular level and have a bearing on the ferlity potenal of a couple.

However, certain iniate treatment but the final decision may be le to circumstances may warrant iniaon of treatment the paent aer explaining all pros and cons and an before taking the vaccine, for instance, informed consent taken before starng treatment. The vaccine can be taken as and when it becomes available. Prevention of infection Though risk migaon measures like wearing a mask, maintaining hand hygiene and social distancing remain the best prevenve strategy, availability of vaccines have provided a new hope of curtailing the virus and averng further waves of Covid 19. Generally, any vaccine which is available can be taken by those seeking pregnancy with the excepon of live aenuated one to avoid harm in case of accidental pregnancy. For paents who have already been infected with COVID, IFS advises to take the vaccinaon in order to enhance their immunity and dampen the effect of a re infecon if it occurs. The various covid vaccines are being developed using different plaorms like nucleic acid based, viral vector based, protein
